Introduction to Jizi Cave: According to legend, Jizi Cave was the place where Jizi, the originator of Go, in the Shang Dynasty used to perform astronomy, divination, and chess planning. The widely circulated story in Weishui Village of Lingchuan County about Father Li watching chess and playing "bad chess" happened here. The cave is about 10 meters deep and 4 meters high. There is a trace on the rock inside the cave that closely resembles the lines of a Go board and an indentation that looks like a Go piece. Clear springs flow in the cave all year round, and the outer wall of the cave is engraved with the inscription "Jizi Cave" by Chen Zude, the director of the Chinese Chess Academy.
