Cuju (蹴鞠) is an ancient Chinese ball game that is the earliest known recorded game similar to football. It is a competitive game that involves both teams trying to kick a ball through an opening into a central hoop without the use of hands whilst ensuring the ball does not touch the ground. This is similar to how hackey-sack is played today. Descriptions of the game date back to the Han dynasty, with the first mention of cuju being in a section on the state of Qi in Warring States era Zhan Guo Ce.
It is also described in Sima Qian's Han Dynasty era Records of the Grand Historian under the Biography of Su Qin as a military exercise for cavaliers in a competitive form while other forms were played for entertainment in wealthy cities like Linzi. It is said that the Han emperor Wu Di enjoyed the sport.
Cuju games were soon standardized and rules were established. Cuju matches were often held inside the imperial palace. A type of court called ju chang (鞠場) was built especially for cuju matches, which had six crescent-shaped goal posts at each end.
The sport was improved during the Tang dynasty (618–907). First of all, the feather-stuffed ball was replaced by an air-filled ball with a two-layered hull. Also, two different types of goal posts emerged: One was made by setting up posts with a net between them and the other consisted of just one goal post in the middle of the field. The Tang dynasty capital of Chang'an was filled with cuju fields, in the backyards of large mansions, and some were even established in the grounds of the palaces. Soldiers who belonged to the imperial army and Gold Bird Guard often formed cuju teams for the delight of the emperor and his court. The level of female cuju teams also improved. Cuju even became popular amongst the scholars and intellectuals, and if a courtier lacked skill in the game, he could pardon himself by acting as a scorekeeper.
Cuju flourished during the Song dynasty (960–1279) due to social and economic development, extending its popularity to every class in society. At that time, professional cuju players were popular, and the sport began to take on a commercial edge. Professional cuju players fell into two groups: One was trained by and performed for the royal court (unearthed copper mirrors and brush pots from the Song often depict professional performances) and the other consisted of civilians who made a living as cuju players. During this period only one goal post was set up in the center of the field.
