Go board introduction: The Go board is located on the chessboard peak in the upper part of Taixu Cave. It was a resting place for Taoist priests from the Jin Dynasty to play chess. The chessboard is carved in the center of the square stone and is a square with a side length of 62 cm, with 19 vertical and horizontal squares. After hundreds of years of wind and rain erosion, the chessboard carvings have become slightly blurred. One person can sit on each end of the chessboard, and there is no barrier on the north side, which is about 50 meters above the ground.
