Cuju involved a great degree of complexity and changed and developed over time. It could be played competitively or cooperatively, in a team or individually, and was often played for purely aesthetic reasons. The non-competitive version was called baida, with the range of skills that players sought to master known as xieshu. Competitive cuju featured two teams whose object was to outscore one another.
One of the best descriptions of a game of cuju dates from the latter stages of the Han dynasty (the period from 25 to 220, also known as the Eastern Han) and is by the poet Li You. Li You’s poem attests that cuju was seen as more than just a form of entertainment or military training. It was regarded as a metaphor for leading a good life.
“A round ball and a square wall,
Just like the Yin and Yang.
Moon-shaped goals are opposite each other,
Each side has six in equal number.
Select the captains and appoint the referee(s),
Based on the unchangeable regulations.
Don’t regard relatives and friends,
Keep away from partiality.
Maintain fairness and peace
Don’t complain of other’s faults,
Such is the matter of cuju.
If all this is necessary for cuju.
How much more for the business of life”.
