Classic of Arts

The Classic of Arts (Chinese: 艺经, pinyin: Yi Jing) was a 3rd-century Chinese book written by Handan Chun on the various cultivated arts of ancient China. The book also briefly discussed some basics of the game of go, and it was the first to state the 9 Pin Zhi, a system for Go ranks and ratings. Although the earliest surviving complete manual on the game is the 6th century Dunhuang Go Manual.
