Many friends prefer playing chess. Some friends who have just learned chess will see the boundary of Chu River and Han Dynasty on the chessboard. If they don't know much about history, they don't know the historical figures related to the Chu River and the Han Dynasty. So, which two historical figures are the archetypes of China's chess board? The chessboard of China chess is based on the stories of two historical figures, Liu Bang and Xiang Yu. There is a Chu Jianghan Dynasty playing chess. Han Shu of Chu River is about Liu Bang's battle with Xiang Yu's army. At that time, Liu Bang and Xiang Yu's army were in a stalemate, and Liu Bang had been fighting here. After a long time, the food and grass on Chu's side gradually decreased. Later, the two sides held peace talks and reached a non-aggression rule. After dividing the border, the Chu River and the Han Dynasty were formed.
