China's chess, like Weiqi, was black first. I don't know when it was changed to Hongxian. It seems to be related to two things.
First, in order to promote China Chess, "China Chess" was renamed as "Chess", which was first black and then red. "Chess" is actually "Indian chess", and it is not hacked first, so it is not hacked first, so as not to cause misunderstanding.
Secondly, it is said that Mr Zhu of Choutry likes playing chess. In order to respect him, let him take the red chess first, because he is the "handsome" of the whole army and cannot be made a "general". Over time, he formed a habit. Later, when He Laoshi was in charge of sports, he defined this habit as chess rules.
