What abilities did China need for archery with bow in ancient times?

Traditional bows need a lot of practice to shoot accurately. The traditional bow in China is made of recurve bow made of composite materials, and there is no bow window. The forehand thumb is used as an arrow stand to take the arrow, and the backhand hand uses Mongolian shooting method, that is, the thumb pulls the string and the forefinger hooks the thumb to pull the bow, so the consistency of each movement is relatively poor, and people interfere with the arrow more, so the traditional bow needs a lot of practice.
