Explanation:
Cuju, the soccer-like game in China, was introduced during the time of Qin Dynasty from 255 BC to 206 BC. Its popularity grew during the reign of the Han Dynasty's Emperor from 206 BC to 220 AD.
Initially, Cuju was played to train soldiers during the Qin Dynasty. It became a part of the Emperor's birthday celebration during the Han Dyanasty.
Cuju was played by both men and women. Its ball was made out of leather stuffed with soft fillings like fur. No hands must be used in playing the game. The ball must be kicked inside a net or a small hole. Team work is not needed since the focus of the game is to observe an individual's skills.
