'm able to resist and pushing me and I'm fairly relaxed with strength I can resist this push and how hard were you pushing there? 100% he's putting all his strength in there and I'm just standing there not using too much strength so the key is don't fight strength don't fight force with force so in Tai Chi you'll teach you how to use structure the structure of your skeletal structure of your bones, of your joints, of your alignment and also of your mind of what the intention is in order to resist using just structure so one of the key things that you need to have structure well there's three mistakes that people make that destroy structure in Tai Chi and very few people that actually practice Tai Chi actually know and actually experience and know how to do this so stay tuned and I'm going to show you those to you mistake number three is not being relaxed so a lot of people are confused about relaxation and about being placid for example if I'm being placid he pushes and that's placid there's nothing there nothing, it's placid but being relaxed in a concept called shong in Chinese it's being loose but relaxed but still have structure so he's pushing harder, harder, harder my hands relax when he's pushing harder, harder see how I relax my arms and I'm still able to resist them okay so that's the difference between being shong which means loose and placid but in English we use the word relaxation which is very easy to misinterpret so number one key when you practice your Tai Chi for example practice your Tai Chi your hands are always relaxed there's only a 10 state and a relaxed state now when we go to the gym, most people practice being tense use your muscles, tense up to get more power which is okay, it works but if you practice being tense all the time practice being tense then if you're fighting against someone bigger than you you're at a disadvantage because his force will be stronger than your force so rather than use force I use Song I use relaxation so when you practice your Tai Chi make sure that your hands are not open like this because that's too much tension because your hands are not closed like this because that's too much tension your hands should always be in the middle when it's relaxed it's completely relaxed imagine holding an egg in your hand when you're open, just open them slightly just stretch them out a little bit when you're relaxed when you're open, just open a little you always want to feel an energy ball in the palms of your hands so it's very subtle for example when I do this, I'm combining two things first of all, my hands are lifting up at the same time my hands are going from relaxed to slightly open and then back to relaxed slightly open it's a very minor detail but what that does is it teaches you even though you're using tension see my hands are slightly open that I'm still in a relaxed state so I never go from I never go up to 100% I go up to maybe 60 to 70% tension never go above that because once you go above that, then you start to use force you stay below let's say 60% tension then you're not using force, you're using relaxation and the key to Tai Chi is know that you can still use relaxation at 60%, 50%, 40%, 30% eventually using no tension at all to be able to resist someone with force so that's what takes the training that's what takes the many many hours of repetition and training doing the push hands that we just showed you in the demonstration doing that for a lot, then you can learn how to use relaxation mistake number two in Tai Chi is to not use your dan tian or not use your core center of gravity to direct the movements so there's a very simple movement called followed hands so I'm using my core to direct my body the same I'm using just one hand see how my core is moving in a circle to direct my arm so the core or the dan tian leads the arms sun dai sao, that's what I say in Chinese the body leads the hand so that's number two mistake here's how it looks like when you make the mistake see a difference my hand is leading my core so there's very little power or connection when I'm moving my hand I'm just moving my hand I'm not even leading it with the core now here's what you're doing correctly so how you can practice is actually put your finger or put your hand and fingers touch your belly button and then feel it move before your hand moves so now you get the difference and the difference let's see I'm just using my hand just my hand pain wise how much is that? 1 to 10 about a 4 now I'm using my hip I mean using my dan tian how much pain more pain is there 7 and I didn't use more power I just used my waist and if I use more I can get it up to 10 so that's the key of generating power is to use your dan tian so let me show you demonstration in the 24 move tai chi form how to use the dan tian to guide your hands so let me show you the wrong way of doing this I'm trying very hard to doing the wrong way because I practice so much the proper way but what I'm doing is I'm leading with my hand and then I move my body so a very basic fundamental in early tai chi if you're a beginner is to learn how to move your hips now when you get advanced tai chi you actually do the opposite you learn to move your hands before your hips it's contradictory isn't it but I'll show you how to do that in the next lesson or the later lesson and it goes with the concept that Bruce Lee taught which is to move your hands before your feet just like in fencing you want to move your hands before your feet the reason is because when somebody attacks you I don't have time to move my hip first and do a big tai chi move right if somebody attacks me I have to move my hand first so what's the difference see before you learn tai chi and once you learn tai chi they move their hands first but there's no power and then they practice tai chi and then they'll learn how to use the hips to get power but they practice enough tai chi and now they'll go back to the beginning they use their hands first but now it comes with power how does that happen so let me show you again let's see his attacking I don't have time to move my hips and do a big tai chi move like in a lot of demonstrations I only have time to just move my hand up I just move my hand I move my hand and then my body go do it again I move my hand and then my body I didn't move my hip first just moving my hips first too slow right, I have to go one, two you already hit me but now I want to do it so that I move my hand first so how does that work maybe in a later lesson I can show you how to do that mistake number one that you can make in tai chi is to not sink your tailbone which means not to open your back now I'm going to show Will for example because I'm wearing a jacket you can see if you take this shirt and tighten it up his spine has a curve here so most people have that curve naturally but in tai chi you actually don't want that curve in tai chi you want to get rid of that curve so you want to sink down the tailbone so that you can feel that this is flatter and ideally it's actually C is a couple so what you need to do is sink your tailbone down even more suck in your gut and then stretch this out like this so now I can feel his lower back straining up but still not enough, you want him to stick out push out over here, push push push that's better so now you can feel that it's more like a C where I started about before see how it's like an S so you don't want that and you can see a lot of people doing tai chi with a back like this it's actually very bad for your back and also it makes you disconnected it disconnects your upper body with your lower body the key to having a strong core and dan tian is to connect your upper body with your lower body and this is the main mistake that people make by having the S curve of the spine and what it does is disconnects your body so for example for the S curve on purpose my spine is like my belly sticking out I'm trying to and he pushes on my hand see I'll automatically go back, there's no resistance but now I stick my back out I drop my hip I make this into a C and now he pushes on it what happens it's a different it's rooted your back is now that energy transfer goes straight through your spine and then into your hips and into the legs, into the knees and into the ground when you break that connection by curving your spine now all the energy just goes in your spine it doesn't go to your legs so that's why he pushes that energy goes to the spine and then I go so that's the number one mistake that you can make in tai chi make sure that you always check put my hand back behind my back it's straight, it's a C you don't want to be like this so even when you do your moves think about that think that the spine is going to be straight one exercise you can do is to do very slow squats against the wall I want to first put my back against the wall and then see if there's any space behind my back see if I slip my hand behind my back if there's a space that I can slip my hand behind then there's too much space so I need to get rid of that space I want all my spine to be touching the wall once I get that then I can go up and down just go half way and go back up sliding my spine up and down the wall now after I do that and I'm good at it then I can go all the way down all the way down keeping my spine straight and touching the wall all the way and do it slow like this so that's going to be very hard on your lower back but it strengthens your lower back it strengthens your leg so that's one key in Tai Chi of creating connectedness so stay tuned I'm going to show you the bonus mistake that people make so the bonus mistake that you can make in Tai Chi is doing it too fast I know everybody says this you want to do Tai Chi slow people don't understand why you do Tai Chi so slow today we talked about three mistakes 1. relaxation 2. using your dan tian to lead your hands 3. having a proper spine alignment what do all those things mean all those things mean connectedness of your whole body integration of your whole body if your hand moves your whole body moves if your feet move your whole body moves then everything is connected and the reason we do Tai Chi so slow is that we are training that connectedness and it's impossible to train it doing it fast that's why we do it slow if we can do it fast and still get connectedness then everybody would do Tai Chi fast but the reason we do it slow is because Tai Chi doing it slow is probably the only way you can train that connectedness in your body by combining all the techniques that we learned relaxation leading with the dan tian and later on how to use your breath to relax and connect your body to and your mind so there's many aspects of learning how to connect your whole body and mind as an integrated machine integrated unit in order to function totally and holistically when it comes in you sink your chest so you press here so you're pushing down to my neck just expand my chest there's actually sink your chest and expand your chest so now there's another not going mechanism that blends so there's blending and it's sinking more so when you're sinking it sinks down to the bottom so the chin is tucked chest is in and you push hard as well it's not going anywhere you expand a bit and you don't want to bounce so you contract easily when we balance so hard because when you can try you feel like oh I can push the guy you feel like you can push me you think you got me don't use that don't use this just relax when you push on here I'm totally relaxed I'm just using my whole structure in my body so this is actually touching my body so you feel like you got me there's actually more there's more room just relax this whole thing suck in there so it feels like oh yeah I got you now but you feel like now it's on your back leg right now you just expand yeah okay I'm so new okay so Glenn put that into your pushing I'm already sucked in but then you need to make sure the elbow so if I go like this you can just push it up there you do that elbow me and we think I control the elbow I don't right then if you feel yourself moving this way you're gonna change it to here here so you need to in, cut the elbow is this sucking in just a second and then expand step here and I'm bumping to you like that right step through deeper my feet haven't touched the ground yet and they've already made contact so now all the momentum is going through you instead of going to the ground you can try that I'll stand here and you can try so you gotta step really deep so I step with this foot or this one like that so that works too but that's not the technique so I step deeper today you want to take my place so here's my center so my foot basically has to be here oh yeah let's see how deep you have to go so but then don't need for you straight boom it's almost straight one straight I'm trying to drop my height down cause I feel like when I get here my shoulders here there's one technique is to use your shoulder that's where I come back cause you can use your shoulder bone but for training you're just going to bump with your chest like that so relax your shoulder don't do this like that but don't stick it out like this I'm trying to pull it back so just relax you're not stepping deep enough so you you don't want to step then go you have to go you have to pay before I land so before my foot even touches the ground I'm already there or the same time so there you go I can feel that a lot more but you step first so you want to aim for it behind again another thing is to make a frame make this round sink your chest so this is like one big one big cup one big cup is gone cause you stick out any part of the cup then it's just going to go in that won't affect the whole thing so you make this round you go so there's two ways you can sink down or you can rise up that's rising up so you go rising up or you can sink down same idea right so now you just extend this and now you're bringing your whole body into it so I'm going to show you the three mistakes in Tai Chi that are very common that people make the main advantages of learning Tai Chi is for health for your joints, for your bones for everything, for relaxation and meditation but also you learn a concept called rooting or sinking so as you can see in the demonstration we'll hear how much do you weigh 220 pounds look at his muscles, his arms, holy cow he's as big as my leg I'm only about 150 pounds look at my skinny arms and I'm able to resist and pushing me and I'm fairly relaxed without using a lot of strength I can resist this push and how hard were you pushing there he's putting all his strength in there and I'm just standing there not using too much strength so the key is don't fight strength don't fight force with force so in Tai Chi you'll teach you how to use structure the structure of your skeletal structure of your bones, of your joints, of your alignment and also of your mind of what the intention is of being just structure so one of the key things that you need to have structure well there's three mistakes that people make that destroy structure in Tai Chi and very few people that actually practice Tai Chi actually know and actually experience and know how to do this so stay tuned and I'm gonna show you those to you mistake number three is not being relaxed so a lot of people are confused about relaxation and about being there's two different things for example if I'm being placid he pushes and that's placid there's nothing there nothing, it's placid but be relaxed in a concept called shong in Chinese it's being loose but relaxed but still have structure so he's pushing harder, harder, harder my hands relax when he's pushing harder, harder see how I relax my arms I'm still able to resist them okay so that's the difference between being shong which means loose and placid but in English we use the word relaxation which is very easy to misinterpret so number one key when you practice your Tai Chi for example, practice your Tai Chi your hands are always relaxed there's only a 10 state and a relaxed state now when we go to the gym, most people practice being tense use your muscles, tense up to get more power which is okay, it works but if you practice being tense all the time practice being tense then if you're fighting against someone bigger than you you're at a disadvantage because his force will be stronger than your force so rather than use force I use Song I use relaxation so when you practice your Tai Chi make sure that your hands are not open like this because that's too much tension because your hands are not closed like this because that's too much tension your hands should always be in the middle when it's relaxed, it's completely relaxed imagine holding an egg in your hand when you're open, just open them slightly just scratch them out a little bit when you're relaxed, relaxed when you're open, just open a little you always want to feel an energy ball in the palms of your hands so it's very subtle for example, when I do this I'm combining two things first of all, my hands are lifting up at the same time my hands are going from relaxed to slightly open and then back to relaxed slightly open it's a very minor detail but what that does is I choose you even though you're using tension see my hands are slightly open that I'm still in a relaxed state so I never go from I never go up to 100% I go up to maybe 60 to 70% tension never go above that because once you go above that, then you start to use force you stay below let's say 60% tension then you're not using force, you're using relaxation and the key to Tai Chi is that you can still use relaxation at 60%, 50%, 40%, 30% eventually using no tension at all to be able to resist someone with force so that's what takes the training that's what takes the many many hours of repetition and training doing the push hands that we just showed you in the demonstration doing that for a lot, then you can learn how to use relaxation mistake number two in Tai Chi is to not use your Dan Tian or not use your core the center of gravity to direct the movements so there's a very simple movement called followed hands I'm using my core to direct my body this time I'm using just one hand see how my core is moving in a circle to direct my arms so the core or the Dan Tian leads the arms Sun Dai Sao, that's what I say in Chinese the body leads the hand so that's number two mistake here's how it looks like when you make the mistake see a difference my hand is leading my core so there's very little power or connection when I'm moving my hand I'm just moving my hand I'm not even leading it with the core now do as you're doing correctly so how you can practice is actually put your finger or put your hand and fingers touch your belly button and then feel it move before your hand moves so now you get the difference and the difference you can tell let's see I'm just using my hand just my hand pain wise how much is that? 1 to 10 about a 4 now I'm using my hip I mean using my Dan Tian how much pain more pain is there a 7 and I didn't use more power I just used my waist and if I use more I can get it up to 10 that's the key of generating power is to use your Dan Tian so let me show you demonstration in the 24 move Tai Chi form how to use the Dan Tian to guide your hand so let me show you the wrong way of doing this I'm trying very hard to do it the wrong way because I practice so much the proper way but what I'm doing is I'm leading with my hands and then I move my body so a very basic fundamental in early Tai Chi if you're a beginner is to learn how to

move like in a lot of demonstrations I only have time to just move my hand up but there's power there I just move my hand move my hand and then my body do it again I move my hand and then my body I didn't move my hips first just moving my hips first too slow, right? I have to go one, two you already hit me but now I want to do it so that I move my hand first so how does that work maybe in a later lesson I can show you how to do that mistake number one that you can make in Tai Chi is to not sink your tailbone which means not to open your back now I'm going to show Will because I'm wearing a jacket you can't see so you see if you take your shirt and tighten it up your spine has a curve here so most people have that curve naturally but in Tai Chi you actually don't want that curve in Tai Chi you want to get rid of that curve so you want to sink down the tailbone so that you can feel that this is flatter and ideally it's actually a C it's a couple so what you need to do is sink your tailbone down even more sucking your gut and then stretch this out like this so now I can feel it's lower back it's straightening up but still not enough, you want it to stick out you push out over here, push, push, push that's better so now you can feel that it's more like a C where I started about before see how it's like an S so you don't want that and you can see a lot of people doing Tai Chi with a back like this it's actually very bad for your back and also it makes you disconnected it disconnects your upper body with your lower body the key to having a strong core and Dan Qian is to connect your upper body with your lower body and this is the main mistake that people make by having the S curve of the spine and what it does is disconnects your body so for example for the S curve on purpose my spine is like my belly sticking out I'm trying to and he pushes on my hand see I'll automatically go back, there's no resistance but now I stick my back out I drop my hip I make this into a C and now he pushes on it what happened it's different you're more rooted see what happens when you curve your back is now that energy transfer goes straight through your spine and into your hips and into the legs into the knees and into the ground when you break that connection by curving your spine now all the energy just goes in your spine it doesn't go to your legs so that's why he pushes that energy goes to the spine and then I go so that's the number one mistake that you can make in Tai Chi so when you practice your Tai Chi make sure that you always check put my hand back behind my back it's straight, it's a C you don't want to be like this so even when you do your moves think about that think that the spine is going to be straight one exercise you can do is to do very slow squats against the wall I want to first put my back against the

space I want all my spine to be touching the wall once I get that then I can go up and down just go halfway and go back up sliding my spine up and down the wall now after I do that and I'm good at it then I can go all the way down keeping my spine straight and touching the wall all the way and go very slow like this so that's going to be very hard on your lower back but it strengthens your lower back it strengthens your leg so that's one key in Tai Chi of creating connectedness so stay tuned I'm going to show you the bonus mistake that people make so the bonus mistake that you can make in Tai Chi is doing it too fast I know everybody says this you don't want to do Tai Chi slow but many people don't understand why you do Tai Chi so slow well today we talked about three mistakes number one relaxation number two using your dan tian to lead your hands and number three having a proper spine alignment what do all those things mean all those things mean connectedness of your whole body integration of your whole body if your hand moves your whole body moves everything is connected and the reason we do Tai Chi so slow is that we're training that connectedness and it's impossible to train it doing it fast that's why we do it slow if we can do it fast and still get connectedness then everybody would do Tai Chi fast but the reason we do it slow is because Tai Chi doing it slow is probably the only way you can train that connectedness in your body by combining all the techniques that we learned relaxation, leading with the dan tian and later on how to use your breath to relax and connect your body to and your mind so there's many aspects of learning how to connect your whole body and mind as an integrated machine integrated unit in order to function totally and holistically okay so when it comes in you sink your chest so you press here solid here right because you're pushing down to my neck expand my chest there's actually so now there's another not going mechanism that blends right so there's blending try to do it see so when you're sinking it sinks down to the rocket so your chin is tucked chest is in and then you push hard as well and then you can expand a bit full shoulders so you contract easily lose balance alright because when you can try you feel like oh I can push the guy right you feel like you can push me you got me right don't use this just relax when you push on here I'm totally relaxed I'm just using my whole structure in my body so this is actually touching my body so you feel like you got me there's actually more there's more room just relax this whole thing suck in there so it feels like oh yeah I got you now but you feel like now it's on your back leg right now you just expand yeah okay I'm already so new so let's put that into your so you're sucking in already I'm already sucked in but then you need to make sure the elbow so if I go like this you can just push it up there you do that elbow me at least I can control the elbow I don't right then if you feel yourself moving this way you're right there you're gonna change it to here so you need to in, cut the elbow this is sucking in just sucking in and then expand step here and I bump into you like that right every step through deeper my feet haven't touched the ground yet and they've already made contact so now all the momentum is going through you instead of going to the ground you try that I'll stand here and you just try so you gotta step really deep so I'll step with this foot or this one like that so that works too but that's not the technique you want to take my place so here's my center you want to be there so my foot basically has to be here oh yeah see how deep you have it but then don't need for you straight boom it's all straight okay I'm trying to drop my height down I feel like that when I get here my shoulders here this one technique is to use the shoulder that's where I come back up because you can use the shoulder bone what for training you're just going to bump into the chest like that so relax the shoulder don't do this like that don't stick it out like this I'm trying to pull it back so just relax I'm David Wong and in this video we're going to show you the three mistakes in Tai Chi that are very common that people make so one of the main advantages of learning Tai Chi is for health, for your joints for your bones, for breathing for relaxation and meditation but also you learn a concept called rooting or sinking so as you can see in the demonstration we'll hear how much do you weigh 240 pounds look at his muscles his arms holy cow I'm already I'm only about 150 pounds look at my skinny arms and I'm able to resist and pushing me and I'm fairly relaxed without using a lot of strength I can resist this push and how hard were you pushing there about 90 to 100% he's putting all the strength in there and I'm just standing there not using too much strength so the key is don't fight strength but force so in Tai Chi you'll teach you how to use structure the structure of your skeletal structure of your bones, of your joints of your alignment and also of your mind of what the intention is in order to resist force using just structure so one of the key things that you need to have structure well there's three mistakes that people make that destroy structure in Tai Chi and very few people that actually practice Tai Chi actually know and actually know how to do this so stay tuned and I'm going to show you those to you mistake number three is not being relaxed so a lot of people are confused about relaxation and about being placid there's two different things, for example if I'm being placid he pushes and that's placid, right? there's nothing there nothing, it's placid but being relaxed in a concept called relaxation in Chinese it's being loose but relaxed, but still have structure so he's pushing he's pushing harder, harder, harder I'm relaxing, my hands relaxed but he's pushing harder, harder I'm still relaxed see how I relax my arms and I'm still able to resist them so that's the difference between being which means loose and placid but in English we use the word relaxation very easy to misinterpret so number one key, when you practice your Tai Chi for example, practice your Tai Chi your hands are always relaxed there's only a tense state and a relaxed state now when we go to the gym, most people they practice being tense use your muscles, tense up to get more power which is okay, it works but if you practice being tense on time if you practice being tense then if you're fighting against someone bigger than you you're at a disadvantage because his force will be stronger than your force so rather than use force I use Song I use relaxation so when you practice your Tai Chi make sure that your hands are not open like this because that's too much tension because your hands are not closed like this your hands should always be in the middle when it's relaxed it's completely relaxed imagine holding an egg in your hand when you're open, just open them slightly just stretch them out a little bit when you're relaxed relaxed when

eventually using no tension at all to be able to resist someone with force so that's what takes the training many many hours of repetition and training doing the push hands that we just showed you in the demonstration doing that for a lot that you can learn how to use relaxation mistake number two in Tai Chi is to not use your dan tian or not use your core center of gravity to direct the movements so there's a very simple movement called followed hands so I'm using my core to direct my body so say I'm using just one hand see how my core is moving in a circle to direct my arm so the core or the dan tian leads the arms that's what I say in Chinese the body leads the hand so that's number two mistake here's how it looks like when you make the mistake my hand is leading my core so there's very little power or connection when I'm moving my hand I'm just moving my hand I'm not even leading it with the core now do as you're doing correctly so how you can practice is actually put your finger or put your hand and fingers touch your belly button and then feel it move before your hand moves so now you get the difference and the difference you can tell, let's see I'm just using my hand like this just my hand like pain wise how much is that 1 to 10 about 4 now I'm using my hit I mean using my dan tian how much pain more pain is there brings it up to about 7 and I didn't use more power I just used my twist and if I use more I can get it up to 10 so that's the key of generating power is to use your dan tian so let me show you a demonstration in the 24 move tai chi form of how to use the dan tian to guide your hands so let me show you the wrong way of doing this I'm trying very hard to do it the wrong way because I practice so much the proper way but what I'm doing is I'm leading with my hands and then I move my body so a very basic fundamental in early tai chi if you're a beginner is to learn how to move your hips when you get advanced tai chi you actually do the opposite you learn to move your hands before your hips it's contradictory isn't it but I'll show you how to do that in the next lesson and it goes with the concept that Bruce Lee taught which is to move your hands before your feet just like in fencing you want to move your hands before your feet the reason is because when somebody attacks you I don't have time to do my hip first and do a big tai chi move right if somebody attacks me I have to move my hand first so what's the difference see before you learn tai chi they move their hands first but there's no power and then they practice tai chi and then they'll learn how to use the hips to get power but they practice enough tai chi and now they'll go back to the beginning they use their hands first but now it comes with power how does that happen what you see is attacking I don't have time to move my hips and do a big tai chi move like in a lot of demonstrations I only have time to just move my hand up but there's power there how does that happen I just move my hand I'm not moving my hand and then my body go do it again I move my hand and then my body I didn't move my hip first just me moving my hips first too slow you already hit me but now I want to do it so that I move my hand first how does that work maybe in a later lesson I can show you how to do that mistake number one that you can make in tai chi is to not sink your tailbone which means not to open your back now I'm going to show Will for example because I'm wearing a jacket you can't see you see if you take your shirt and tighten it up it has a curve here most people have that curve naturally but in tai chi you actually don't want that curve in tai chi you want to get rid of that curve so you want to sink down the tailbone so that you can feel that this is flatter and ideally it's actually a C it's a couple so what you need to do is sink your tailbone down even more suck in your gut and then stretch this out like this so now I can feel it's lower back straightening up you want it to stick out push out here so now you can feel that it's more like a C where I started out before see how see how it's like an S so you don't want that and you can see a lot of people doing tai chi with a back like this it's actually very bad for your back and also it makes you disconnected it disconnects your upper body with your lower body the key to having a strong core and dan tien is to connect your upper body with your lower body and this is the main mistake that people make by having the S curve of the spine and what it does is disconnects your body so for example I'm going to do an S curve on purpose my spine is like my belly sticking out and he pushes on my hand see I'll automatically go back no resistance but now I stick my back out I drop my hip and make this into a C and now he pushes on it what happened? it's a different it's more rooted see what happens when you curve your back is now that energy transfer goes straight through your spine and then into your hips and into the legs and knees break that connection by curving your spine now all the energy just goes in your spine it doesn't go through your legs so that's why he pushes that energy goes into the spine and then I go so that's the number one mistake that you can make in Tai Chi so when you practice your Tai Chi make sure that you always check put my hand back behind my back and see if it's straight if it's a C you don't want to be like this think about that think that the spine is going to be straight one exercise you can do is to do very slow squats against the wall so this is the wall against me I want to first put my back against the wall and then see if there's any space behind my back see if I slip my hand behind my back if there's a space that I can slip my hand behind then there's too much space so I need to get rid of that space I want all my spine to be touching the wall so when I get that then I can go up and down just go halfway and go back up sliding my spine up and down the wall now after I do that and I'm good at it then I can go all the way down keeping my spine straight and touching the wall all the way and do it slow like this so that's going to be very hard on your lower back but it strengthens your lower back it strengthens your leg so that's one key to making Tai Chi of creating connectedness so stay tuned I'm going to show you the bonus mistake that people make so the bonus mistake that you can make in Tai Chi is doing it too fast I know everybody says this you want to do Tai Chi slow but many people don't understand why you do Tai Chi so slow well today we talked about three mistakes number one relaxation number two using your Dan Tian to lead your hands a proper spine alignment what do all those things mean all those things mean connectedness of your whole body integration of your whole body if your hand moves your whole body moves if your feet move your whole body moves everything's connected and the reason we do Tai Chi so slow is that we're training that connectedness and it's impossible to train it doing it fast that's why we do it slow if we can do it fast and still get connectedness then everybody would do Tai Chi fast but the reason we do it slow is because Tai Chi doing it slow is probably the only way you can train that connectedness in your body by combining all the techniques that we learned relaxation leading with the Dan Tian and later on how to use your breath to relax and connect your body too and your mind so there's many aspects of learning how to connect your whole body and mind as an integrated machine integrated unit in order to function totally and holistically another technique is when it comes in you sink your chest so you press here like I'm pretty solid here because you're pushing down to my back expand my chest but there's actually so now there's another not going mechanism that blend so there's blending try and do it see so when you're sinking it sinks down to the bottom your chin is tucked and your chest is in and then you push hard as more it's not going anywhere expand a bit pull the shoulders so you contract yeah easily where we balance because when you can try and you feel like oh I can push the guy you feel like you can push me you think you got me right don't use this don't use this just relax when you push in here I'm totally relaxed I'm just using my whole structure in my body so this is actually touching my body so you feel like you got me there's actually more there's more room just relax just relax this whole thing suck in there so it feels like oh yeah I got you now but you feel like now it's on your back leg right now you just expand yeah okay alright it's all new okay ready? I'm already sucked in yeah but then you need to make sure the elbow cap the elbow so if I go like this push it up there when you try to elbow me you do that elbow me at least I can control the elbow right then if you feel yourself moving this way you're right there you're going to change it to here alright in this is sucking in just sucking in and then expand step here and I bump into you like that right? step through deeper see that my feet haven't touched the ground yet and they've already made contact so now all the momentum is going through you instead of going to the ground okay I'll stand here and you just try so you got to step really deep so I step with this foot or this one like that so that works too but that's not the technique so I'm here you want to take my place so here's my center you want to be there so my foot basically has to be here yeah see how deep you have to go that's better you straight? boom, it's almost straight one straight I'm trying to drop my height down because I feel like when I get here my shoulder is here don't use your shoulder is this one technique to use your shoulder? that's for a more combata because you can use your shoulder bone but for training you're just going to bump into your chest okay so relax your shoulder okay yeah like that don't stick it out like this I'm trying to pull it back so just relax you're not stepping people down I feel that when I step here so you don't want to step then go you have to pay before I land okay so before my foot even touches the ground I'm already there yeah there you go I can do that a lot more but you step first so you want to aim before and behind again the thing is to make a frame make this round sink your chest so there's like one big one big cup one big cup is gone because you stick out any part of the cup then it's just going to go in it won't affect the whole thing so you make this round you go so there's two ways you can sink down or you can rise up that's rising up so you go rising up or you can sink down so it's like you got it so now you just extend this and now you're bringing your whole body into it so don't push okay in this video I'm going to show you the three mistakes in Tai Chi that are very common that people make so one of the main advantages of learning Tai Chi is for health for your joints, for your bones for breathing, for relaxation and meditation but also you learn a concept called rooting or sinking so as you can see in the demonstration we'll hear how much do you weigh 240 pounds look at his muscles look at his arms, holy cow he's as big as my leg I'm only about 150 pounds look at my skinny arms and I'm able to resist and pushing me and I'm fairly relaxed without using a lot of strength I can resist this push and how hard were you pushing there he's putting all his strength in there and I'm just standing there not using too much strength don't fight force with force so in Tai Chi you'll teach you how to use structure the structure of your skeletal structure of your bones, of your joints, of your alignment and also of your mind of what the intention is in order to resist force using just structure so one of the key things that you need to have structure well there's three mistakes that people make that destroy structure in Tai Chi and very few people that actually practice Tai Chi actually know the experience and know how to do this so stay tuned and I'm going to show you those to you mistake number three is not being relaxed so a lot of people are confused about relaxation and about being placid there's two different things for example if I'm being placid he pushes and that's placid right there's nothing there a shong in Chinese it's being loose but relaxed but still have structure so he's pushing he's pushing harder, harder, harder I'm relaxing, my hands relaxing he's pushing harder, harder I'm still relaxed he helps me relax my arms and I'm still able to resist them so that's the difference between being shong which means loose and placid but in English we use the word relaxation which is very easy to misinterpret so number one key when you practice your Tai Chi for example, practice your Tai Chi your hands are always relaxed there's only a tense state and a relaxed state now when we go to the gym most people practice being tense use your muscles tense up to get more power okay, it works but if you practice being tense all the time like this then if you're fighting against someone bigger than you you're at a disadvantage because his force will be stronger than your force so rather than use force I use shong I use relaxation so when you practice your Tai Chi make sure that your hands are not open like this because that's too much tension your hands should always be in the middle when it's relaxed it's completely relaxed imagine holding an egg in your hand when you're open just open them slightly just stretch them out a little bit when you're relaxed, relaxed when you're open, just open a little you always want to feel an energy ball in the palms of your hands so it's very subtle for example, when I do this I'm combining two things first of all, my hands are lifting up at the same time my hands are going from relaxed to slightly open and then back to relaxed slightly open it's a very minor detail, but what that does is it teaches you to even though you're using tension see my hands are slightly open that I'm still in a relaxed state so I never go from I never go up to 100% maybe 60 to 70% tension never go above that because once you go above that then you start to use force if you stay below let's say 60% tension then you're not using force you're using relaxation and the key to Tai Chi is to train yourself so that you can still use relaxation at 60%, 50%, 40%, 30% eventually using no tension at all to be able to resist someone with force so that's what takes the training that's what takes the many many hours repetition and training doing the push hands that we just showed you in the demonstration doing that for a lot, then you can learn how to use relaxation mistake number two in Tai Chi is to not use your dan tian or not use your core center of gravity to direct the movements so there's a very simple movement called followed hands so I'm using my core to direct my body the same I'm using just one hand see how my core is moving in a circle to direct my arm so the core or the dan tian leads the arms sun dai sao that's what I say in Chinese the body leads the hand so that's number two mistake here's how it looks like when you make a mistake see a difference my hand is leading my core so there's very little power connection when I'm moving my hand I'm just moving my hand I'm not even leading it with the core now do this correctly so how you can practice is actually put your finger or put your hand and fingers touch your belly button and then feel it move before your hand moves but now you get the difference and the difference you can tell, let's see I'm just using my hand like this just my hand pain wise how much is that 1 to 10 about a 4 now I'm using my hip I'm using my dan tian how much pain more pain is there a 7 and I didn't use more power I just used my waist and if I use more I can get it up to 10 that's the key of generating power is to use your dan tian so let me show you demonstration in the 24 move tai chi form of how to use the dan tian to guide your hands so let me show you the wrong way of doing this I'm trying very hard to doing the wrong way because I practice so much the proper way but what I'm doing is I'm leading with my hands and then I move my body so a very basic fundamental in early tai chi if you're a beginner is to learn how to move your hips now when you get advanced tai chi you actually do the opposite you learn to move your hands before your hips it's contradictory isn't it but I'll show you how to do that in the next lesson or in a later lesson and it goes with the concept that Bruce Lee taught which is to move your hands before your feet just like in fencing you want to move your hands before your feet the reason is because when I have time to move my hip first and do a big tai chi move if somebody attacks me I have to move my hand first so what's the difference see before you learn tai chi and once you learn tai chi they move their hands first but there's no power and then they'll practice tai chi and then they'll learn how to use the hips to get power but they practice enough tai chi and now they'll go back to the beginning they use their hands first but now it comes with power how does that happen so let me show you again let's see his attacking I don't have time to move my hips and do a big tai chi move I only have time to just move my hand up but there's power there how that happens I just move my hand and then my body I move my hand and then my body I didn't move my hip first just me moving my hips first too slow I have to go one, two you already hit me but now I want to do it so that I move my hand first so how does that work maybe in a later lesson I can show you how to do that mistake number one that you can make in tai chi is to not sink your tailbone which means not to open your back now I'm going to show Will for example because I'm wearing a jacket you can't see so you see if you take this shirt and tighten it up it has a curve here so most people have that curve naturally but in tai chi you actually don't want that curve in tai chi you want to get rid of that curve so you want to sink down the tailbone so that you can feel that this is flatter and ideally it's actually a C it's a couple so what you need to do is sink your tailbone down even more suck in your gut and then stretch this out like this so now I can feel his lower back is straightening up you want it to stick out push out here so now you can feel that it's more like a C where I stand about before see how see how it's like an S so you don't want that and you can see a lot of people doing tai chi with a back like this is actually very bad for your back and also it makes you disconnected it disconnects your upper body with your lower body the key to having a strong core and dan qian is to connect your upper body with your lower body and this is the main mistake that people make by having the S curve of the spine and what it does is disconnects your body so for example I'm going to do an S curve on purpose my spine is like my belly sticking out I'm trying to and he pushes on my hand see there's no resistance but now I stick my back out I drop my hip I make this into a C and now he pushes on it what happened it's more rooted see what happens when you curve your back is now that energy transfer goes straight through your spine and then into your hips and into the legs, into the knees, into the ground when you break that connection by curving your spine now all the energy just goes in your spine it doesn't go to your legs so that's why he pushes that energy goes to the spine and then I go so that's the number one mistake that you can make in tai chi so when you practice your tai chi make sure that you always check put my hand back behind my back and see if it's straight you did a C so even when you do your moves think about that think that the spine is going to be straight one exercise you can do is to do very slow squats against the wall so that's what the wall is going to be I want to first put my back against the wall and then see if there's any space behind my back see if I slip my hand behind my back if there's a space that I can slip my hand behind then there's too much space so I need to get rid of that space I want all my spine to be touching the wall once I get that I go up and down just go halfway and go back up sliding my spine up and down the wall now after I do that and I'm good at it then I can go all the way down all the way down keeping my spine straight and touching the wall all the way and do it slow like this so that's going to be very hard on your lower back but it strengthens your lower back it strengthens your leg so that's why I love creating connectedness so stay tuned I'm going to show you the bonus mistake that people make so the bonus mistake that you can make in Tai Chi is doing it too fast I know everybody says this you want to do Tai Chi slow but many people don't understand why you do Tai Chi so slow well today we talked about three mistakes number one, relaxation number two, using your dan tian to lead your hands and number three, having a line alignment what do all those things mean connectedness of your whole body integration of your whole body if your hand moves your whole body moves if your feet move your whole body moves and the reason we do Tai Chi so slow is that we're training that connectedness and it's impossible to train it doing it fast that's why we do it slow if we can do it fast if we connected this then everybody would do Tai Chi fast but the reason we do it slow is because Tai Chi doing it slow is probably the only way you can train that connectedness in your body by combining all the techniques that we learned relaxation leading with the dan tian and later on how to use your breath to relax and connect your body to and your mind so there's many aspects of learning how to connect your whole body and mind integrated machine integrated unit in order to function totally and holistically when it comes in you sink your chest so you press here like I'm pretty solid here because you're pushing down to my back expand my chest and then you go so there's actually sink your chest and expand your chest so now there's another not going mechanism that blends so there's blending I'll try to do it so when you're sinking it sinks down to the bottom so your chin is tucked your chest is in and then you push hard as well it's not going anywhere expand a bit and you know it's your core yeah so you contract? yeah easy when we balance so hard because when you can try you feel like oh I can push the guy you feel like you can push me you think you got me right don't use this don't use this just relax when you push on here I'm totally relaxed I'm just using my whole structure in my body so this is actually that you in so you feel like you got me right there's actually more alright just relax this whole thing suck in there so it feels like oh yeah I got you now but you feel like now it's on your back leg right now you just expand yeah okay alright I'm already so new already I'm already sucked in but then you need to make sure the elbow so if I go like this push it up when you try to elbow me you do that elbow me at least I can control the elbow right then if you feel yourself moving this way you're you're going to change it to here so you need to in, cut the elbow suck it in just a second and then expand step here and I bump into you like that right? if I step too deeper see that my feet haven't touched the ground yet and I've already made contact so now all the momentum is going through you instead of going to the ground okay I'll stand here and try to bump into that so you got to step really deep with this foot or this one so like that so that works too but that's not the technique so step deeper today you want to take my place so here's my center you want to be there so my foot basically has to be here oh yeah see how deep you have to go so that's better but then don't knee forward boom it's almost straight I'm trying to drop my height down I feel like that when I get here don't use your shoulder one technique is to use your shoulder that's for a more combata because you can use your shoulder bone if you're training you're just going to bump into your chest so relax your shoulder don't do this yeah like that don't stick it out like this I'm trying to pull it back so just relax alright come I'm David Wong and in this video I'm going to show you the three mistakes in tai chi that are very common that people make so one of the main advantages of learning tai chi is for health for your joints, for your bones for breathing, for relaxation and meditation but also you learn a concept called rooting so as you can see in the demonstration we'll hear how much do you weigh 220 pounds look at his muscles, his arms, holy cow he's as big as my leg I'm only about 150 pounds look at my skinny arms and I'm able to resist and pushing me and I'm fairly relaxed without using a lot of strength I can resist this push and how hard were you pushing there I'm learning all the strength in there and I'm just standing there not using too much strength so the key is don't fight strength don't fight force with force so in tai chi you'll teach you how to use structure the structure of your skeletal structure of your bones, of your joints, of your alignment and also of your mind of what the intention is in order to resist force using just structure so one of the key things that you need to have structure is three mistakes that people make that destroy structure in tai chi and very few people that actually practice tai chi actually know and actually experience and know how to do this so stay tuned and I'm going to show you those to you mistake number three is not being relaxed so a lot of people are confused about relaxation and about being placid there's two different things for example and that's placid, right? there's nothing there placid but being relaxed in a concept called shong in chinese it's being loose but relaxed but still have structure so you're pushing it's pushing harder, harder, harder I'm relaxed see, my hands are relaxed when he's pushing, harder, harder I'm still relaxed see how relaxed my arm is I'm still able to resist them that's the difference between being shong which means loose and placid but in english we use the word relaxation which is very easy to misinterpret so number one key when you practice your tai chi for example, practice your tai chi your hands are always relaxed there's only a tense state and a relaxed state now when we go to the gym most people practice being tense use your muscles tense up to get more power which is okay, it works but if you practice being tense all the time practice being tense like this then if you're fighting against someone bigger than you you're at a disadvantage because his force will be stronger than your force so rather than use force I use shong so when you practice your tai chi make sure that your hands are not open like this because that's too much tension because your hands are not closed like this because that's too much tension your hands should always be in the middle when it's relaxed, it's completely relaxed imagine holding an egg in your hand when you're open, just open them slightly just stretch them out a little bit when you're relaxed, relaxed when you're open, just open a little you always want to feel an energy ball in the palms of your hands so it's very subtle for example when I do this I'm combining two things, first of all my hands are lifting up at the same time, my hands are going from relaxed to slightly open and then back to relaxed slightly open it's a very minor detail but what that does is it teaches you to even though you're using tension see my hands are slightly open that I'm still in a relaxed state so I never go from I never go up to 100% I go up to maybe 60 to 70% tension never go above that because once you go above that, then you start to use force if you stay below let's say 60% tension then you're not using force, you're using relaxation and the key to Tai Chi is to train yourself so that you can still use relaxation at 60%, 50%, 40%, 30% eventually using no tension at all to be able to resist someone with force so that's what takes the training that's what takes the many many hours repetition and training doing the push hands that we just showed you in the demonstration doing that for a lot, then you can learn how to use relaxation mistake number two in Tai Chi is to not use your Dan Tian or not use your core center of gravity to direct the movements okay so there's a very simple movement called bowed hands so I'm using my core to direct my body, the same I'm using just one hand see how my core is moving in a circle to direct my arm so the core or the Dan Tian leads the arms that's what I say in Chinese the body leads the hand so that's number two mistake, here's how it looks like when you make the mistake see the difference? my hand is leading my core so there's very little power or connection when I'm moving my hand I'm just moving my hand I'm not even leading it with the core I'll do it correctly so how you can practice is actually put your finger or put your hand and fingers touch your belly button and then feel it move before your hand moves so now you get the difference you can tell let's see, I'm just using my hand just my hand pain wise how much is that? 1 to 10 about a 4 now I'm using my hip I mean using my Dan Tian how much pain more pain is there? about a 7 and I didn't use more power I just used my waist 1 to 10 that's the key of generating power is to use your Dan Tian so let me show you a demonstration in the 24 move Tai Chi form how to use the Dan Tian to guide your hands so let me show you the wrong way of doing this I'm trying very hard to do it the wrong way because I practice so much the proper way but what I'm doing is I'm leading with my hands and then I move my body so a very basic, fundamental in early Tai Chi, if you're a beginner is to learn how to move your hips now when you get advanced Tai Chi you actually do the opposite you learn to move your hands before your hips it's contradictory isn't it

how does that happen so let me show you again I don't have time to move my hips and do a big Tai Chi move in a lot of demonstrations I only have time to just move my hand up but there's power there how does that happen I just move my hand and then my body I move my hand and then my body I didn't move my hip first here's me moving my hips first too slow I have to go one, two you already hit me but now I want to do it so that I move my hand first so how does that work maybe in a later lesson I can show you how to do that mistake number one that you can make in Tai Chi is to not sink your

that curve naturally but in Tai Chi you actually don't want that curve in Tai Chi you want to get rid of that curve so you want to sink down the tailbone you can feel that this is flatter and ideally it's actually a C it's a couple so what you need to do is sink your tailbone down even more suck in your gut and then stretch this out like this so now I can feel it's lower back straightening up but still not enough you want it to stick out so now you can feel that it's more like a C where I started about before see how see how it's like an S so you don't want that and you can see a lot of people doing Tai Chi with a back like this it's actually very bad for your back it makes you disconnected it disconnects your upper body with your lower body the key to having a strong core and Dan Qian is to connect your upper body with your lower body and this is the main mistake that people make by having the S curve of the spine and what it does is it disconnects your body so for example I'm going to do an S curve on purpose my spine is like my belly is sticking out so I'm trying to and he pushes on my hand see I'll automatically go back there's no resistance but now I stick my back out I drop my hip and make this into a C and then now he pushes on it what happened it's different you're more rooted see what happens when you curve your back is now that energy transfer goes straight into your hips and into the legs into the knees and into the ground when you break that connection by curving your spine now all the energy just goes in your spine it doesn't go to your legs so that's why he pushes that energy goes into the spine and then I go so that's the number one mistake that you can make in Tai Chi so when you practice your Tai Chi make sure that you always check put my hand back behind my back this is a C so even when you do your moves think about that think that the spine is going to be straight one exercise you can do is to do very slow squats against the wall I want to first put my back against the wall and then see if there's any space behind my back see if I slip my hand behind my back if there's a space that I can slip my hand behind then there's too much space I need to get rid of that space I want all my spine to be touching the wall once I get that then I can go up and down just go halfway and go back up sliding my spine up and down the wall now after I do that and I'm good at it then I can go all the way down all the way down keeping my spine straight and touching the wall all the way and do it slow like this so that's going to be very hard on your lower back it strengthens your lower back it strengthens your leg so that's one key in Tai Chi of creating connectedness so stay tuned I'm going to show you the bonus mistake that people make so the bonus mistake that you can make in Tai Chi is doing it too fast I know everybody says this you want to do Tai Chi slow but many people don't understand why you do Tai Chi so slow well today we talked about three mistakes number two using your Dantian to lead your hands and number three having a proper spine alignment what do all those things mean all those things mean connectedness of your whole body integration of your whole body if your hand moves your whole body moves if your feet move your whole body moves everything's connected and the reason we do Tai Chi so slow is that we're training that connectedness and it's impossible to train it doing it fast that's why we do it slow if we can do it fast and still get connectedness then everybody would do Tai Chi fast but the reason we do it slow is because Tai Chi doing it slow is probably the only way you can train that connectedness in your body by combining all the techniques that we learned relaxation leading with the Dantian and later on how to use your breath to relax and connect your body too and your mind so there's many aspects of learning how to connect your whole body and mind as an integrated machine integrated unit in order to function totally and holistically when it comes in, you sink your chest it's like press here like I'm pretty solid here because you're pushing down to my head expand my chest and then you go there's actually an expanded chest expanded chest so now there's another not going mechanism that blends so there's blending it's sinking more so when you're sinking it sinks down to the bottom so the chin is tucked chest is in and then you push hard as more it's not going anywhere expand a bit and you know what I'm saying so you contract easily what we're bound to cause when you can try you feel like oh I can push the guy you feel like you can push me you think you got me right don't use this don't use this just relax when you push in here I'm totally relaxed I'm just using my whole structure in my body so this is actually touching my body so you feel like you got me cause actually there's more there's more room alright so just relax this whole thing suck in there so it feels like oh yeah I got you now but you feel like now it's on your back leg now you just expand alright alright so new so Glenn put that into your sucking in things already I'm already sucked in expanding but then you need to make sure cap the elbow so if I go like this push it up but you try to elbow me a bit you do that elbow me if I control the elbow then if you feel yourself moving this way you can just change it to here yeah so you need to in cap the elbow is this sucking in just sucking in and then expand step here and I bump into you like that right? if I step too deeper see that my feet haven't touched the ground yet and they've already made contact so now all the momentum is going through you instead of going to the ground okay I'll stand here and you just try bumping into that so you gotta step really deep so I step with this foot or this one like that so that works too but that's not the technique so step deeper today you want to take my place you want to be there so my foot basically has to be here alright let's see how deep you have to go so but then don't knee forward be straight boom, it's almost straight okay I'm trying to drop my height down I feel like that when I get here my shoulder is here don't use your shoulder one technique is to use your shoulder that's where I come back up because you can use your shoulder bone but for training you're just going to bump with your chest so like that so relax your shoulder don't do this so yeah like that don't stick it out like this I'm trying to pull it back so just relax you're not stepping people down so when I step here one is step then go you have to go you have to pay before I land so before my foot even touches the ground I'm already there yeah or the same time yeah I can feel that a lot more but you step first so you want to aim aim for behind the guy the other thing is to make a frame make this round sink your chest one big cup step because you stick out any part of the cup then it's just going to go in it won't affect the whole thing so you make this round you go alright so there's two ways you can sink down or you can rise up that's rising up so you go that's rising up or you can sink down so it's like going downwards you got it same idea right so now you just extend this so now you're bringing your whole body into it so don't push just like this video I'm going to show you the three mistakes in Tai Chi that are very common that people make so one of the main advantages of learning Tai Chi is for health, for your joints for your bones, for breathing for relaxation and meditation but also you learn a concept called rooting or sinking so as you can see in the demonstration we'll hear how much do you weigh 220 pounds look at his muscles look at his arms, holy cow he's as big as my leg I'm only about 150 pounds look at my skinny arms and I'm able to resist and pushing me and I'm fairly relaxed without using a lot of strength I can resist this push and how hard were you pushing there he's putting all the strength in there and I'm just standing there not using too much strength so the key is don't fight strength don't fight force with force so in Tai Chi you'll teach you how to use structure for the bones of your joints of your alignment and also of your mind of what the intention is in order to resist force using just structure so one of the key things that you need to have structure well there's three mistakes that people make that destroy structure in Tai Chi and very few people that actually practice Tai Chi actually know and actually experience and know how to do this so stay tuned and I'm going to show you those to you mistake number three so a lot of people are confused about relaxation and about being placid there's two different things for example if I'm being placid he pushes and that's placid there's nothing there nothing, it's placid but be relaxed in a concept called shong in Chinese it's being loose but still have structure so he's pushing he's pushing harder I'm relaxing, my hands relaxed but he's pushing harder I'm still relaxed he helps me relax my arms I'm still able to resist them so that's the difference between being shong which means loose and placid but in English we use the word relaxation which is very easy to misinterpret so number one key when you practice your Tai Chi your hands are always relaxed there's only a 10 state and a relaxed state now when we go


Hi, good afternoon. Today, we'll talk about this EnableGPU accelerated on-prime Edge AI computing. So basically, here, the workload is the AI workload. The environment we want to emphasize here is running Edge. And we want to run in the container. For OpenStack, we want to run using DreamProject. So that's basically the purpose of this presentation. So this is the environment we want to discuss about where we use GPU. And before, if we focus on cloud computing, the data from the Edge, from the IoT device, will send to the data center. And the delay is very long. Because this center has the GPU or the computational power. So it's processing the data and then sends the decision back to the Edge. So this introduced long latency. And so that's basically the model of the cloud computing. But for the Edge computing, basically, we move the computational power from data center to the Edge side. Basically, here, in this diagram, basically, it's in the far end edge or the edge aggregator. So why we need a GPU in this environment? It's basically, a lot of application right now require the GPU power. For example, if we handle AR, VR, which related to video, we do some algorithms related to deep learning trainings of the data model. So that involves a lot of computational power which GPU can basically accelerate. So yeah, so basically, there are multiple applications we can help with using GPU. And in this environment, we want leverage, leverage the power of containers. So definitely, the most important part for this is the isolation, especially when we talk about so many applications, different applications, the software stack, usually, are very different. So to use a common host, a common bare metal server, to run this multiple different software stack, container gave us the ideal environment to provide isolation and portability as well. Especially, quite recently, the GPU support on the container environment have some advances. So now it's enabled on Docker containers. And so that's why we want to integrate this work into OpenStack Dream Project. So for the OpenStack Dream Project, before, we don't have the support for GPU. So this is ongoing work we are doing to basically schedule the GPU resource, schedule the workload to the GPU resource, and monitoring the GPU resource. The work is not complete yet, but our testing is based on the testing environment, which have this special code enabled. And how do we use the GPU workload? Basically, if you look at the top, this is a component deployed at this center. On the edge side, it's different. We call this deploy mode. Actually, the deploy mode is called DCN Distributed Computational Compute Node. So in this mode, the networking between the data center to the edge side is using SpanLIF, R3 network, instead of have L2 network involved. So yeah, that's only different than to deploy the DCN node in the data center. You can see that at the edge side, we usually, this one side represents one or two servers. Basically, we have GPU power. We have enabled some open stack component, including Zoom, to provide the contender capability. So the left side of this diagram is copied from NVIDIA, which basically giving the reference architecture how the contender being used in the GPU environment. So I want to emphasize a few points here. Basically, on the host environment, the shared environment, we have to enable CUDA. We have to enable NVIDIA driver. For Docker, it has much better support on GPU since the version 19.03. And right now, it's naturally enabled. We can have, in the API, it's enabled. This new API actually supports GPU. You can specify one or more GPU and assign it to the container. And again, the contender have their own CUDA environment, have their own software stack, which really help to isolate different environment to different applications. We test the solution based on Lenovo hardware. It's called SR5 650, which is a general purpose server. Basically, this hardware requirement, we have two kind of GPU in one host to test. One is NVIDIA V100, which is a newer version. And NVIDIA K80 is kind of the old version five years old about. So we just want to compare the performance. And the software version is quite important here. We tried many different versions. So, and this is for kernel, especially for kernel version, that some kernel works for virtual GPU, some not. So this is we have to do some smart kind of research there. But this is the final one we use CUDA 10.1 Docker 1903. And we run it on Ubuntu. So use this environment, we basically did some benchmarks. So the first benchmark we do is on each container, we just assign a single GPU. And we test the different benchmark algorithm to see what's the performance. If you look at a number here, the number is how many image the algorithm handle per second, which this is a TensorFlow benchmarking. It's quite standard. So there are lots of reference there. If you have interest, I can pass you the information later. So basically, the rest net, the very left one is the most common used benchmark for this kind of activity. We can see there are quite different if we use different GPU card in this setup. And the next test we are running is to see how we can run multiple containers in one host, share one host. Especially, we run multiple containers, share one GPU. So this is a scenario. Basically, we save costs to have one GPU on a single edge server. Because single edge server, usually a small footprint, cannot have multiple GPU card. So this is quite important to see how many containers can share this one GPU without this virtual GPU technology. So basically, the diagram shows five containers, share one GPU. In our test, when we increase the number to six, we basically found some container even cannot get the GPU resource. And one another thing we want to show that is if we treat basically a single container using one GPU as utilization, for example, is 100%, then if we do the sharing or compete the GPU resource with multiple containers, the performance, basically, the utilization is about 85%. So there are definitely some penalty there. So basically, I want to summarize this presentation. We basically discussed how to enable GPU in the edge computing scenario. And there are some ongoing work in the OpenStack Zoom project to support that. We also gave some performance data. Thank you very much. Questions?
