 Li Jing and Li Quan prescribed 20 percent of the infantry to be armed with standard crossbows, which could hit the target half the time at a distance of 345 meters, but had an effective range of 225 meters.During the Song dynasty, the government attempted to restrict the spread of military crossbows and sought ways to keep armour and crossbows out of private homes.Despite the ban on certain types of crossbows, the weapon experienced an upsurge in civilian usage as both a hunting weapon and pastime.
