How many meters per second is the initial velocity of the ancient bow in China?

The arrow speed of the magic pen bow in Song Dynasty is estimated to be between 250-300FPS. It's a little high to see someone speculating that it's above140m/s. The arrows used are relatively heavy, so the kinetic energy is still greater than that of most crossbows on the modern market, and it takes a hundred steps to wear armor.

Not to mention the ancient bow, it is estimated that the bow used by ordinary people can shoot more than 200 FPS.
