May I ask the masters of classical literature, what are the two allusions about "don't drink Chu's wine, don't play prince chess"

Don't drink Chu wine, don't play chess with the prince in the East Palace. After the withdrawal, the rabbit died and the dog boiled. In the battle of the East Palace, the ministers bowed to their knees.

Don't play prince chess in the East Palace, it should refer to the prince of peace. Han Jing killed him with a chessboard because he played six games of chess.
