Why can't General China play chess?
If you want these two generals to face each other directly, there are no soldiers around them. Needless to say, Liu Bang must have been killed directly, so there is a rule that generals can't face each other.
Then the second reason is that the chess game is actually to protect the generals or handsome men at home, and then try to eat the generals or handsome men opposite. If the commander is old enough to face the other side, it means that one of them must have been killed by the other side.
At this time, it is equivalent to losing, so naturally there is a saying that generals can't meet each other, because the role of his chess pieces is to protect their generals and handsome.
This is exactly the same as the ancient kings. If the general has already met, it is useless to play other pieces. Naturally, it can't be called China Chess.
