 The money was referred to as "money warding off evil spirits" () and was believed to protect the person of younger generation from sickness and death.The "yasui qian" was replaced by red envelopes when printing presses became more common and is now found written using the homophone for "sui" () that means "old age" instead of "evil spirits" thus, "money warding off old age" ().Red envelopes continue to be referred to by such names today.
