Go is a game that people often play. Why are the pieces of Go only black and white?

? A small game of Weiqi, which concisely and clearly covers the changes of Yin and Yang in heaven and earth, is vividly compared to the black and white world of Weiqi, and has been a favorite entertainment activity of China people since ancient times. Its origin is very early, and it can be said that it is the originator of all chess. It is said that it was invented by Yao Shunyu and has a history of more than 4,000 years. At that time, due to the frequent wars of plundering land and competing for population, Weiqi aimed at enclosure and mutual surprise in the process of playing chess, and there were many similarities between the two. Therefore, Go became an effective means for nobles to educate their children about military knowledge, and it developed rapidly.

Weiqi is mostly played by two people, divided into sub-chess and sub-chess. The former holds sunspots first, while the latter holds Bai Zi first. After the start, the two sides take turns to make moves at the intersection of the chessboard. Only one move is allowed, and the position will not move after the move. Go moves are complicated and changeable, which are usually divided into three stages: layout, middle play and ending. Finally, the actual vacancies and semicolons will be added up, and more will win, and some will record the actual vacancies. Today, Go 19 was formed in the Han and Wei Dynasties.

Go chess pieces are only black and white. China Sports Museum has black and white round Go chess pieces from Tang Dynasty, and 50 round chess pieces unearthed from Yang Cemetery in Song Dynasty in Huai 'an are also black and white. Generally, there are 150 black and white chess pieces, which are generally round flat chess pieces with one side convex or two sides convex. Black and white chess pieces represent yin and yang respectively. The original meaning of yin and yang refers to cold and heat, and later it has an abstract meaning, which can represent darkness and light, as well as men and women. Chess pieces intersect, ever-changing, and "Yin and Yang".

The round pieces of Go represent the sky, and the square chessboard represents the ground. The black-and-white symmetrical structure of the ancient Taiji diagram symbolizes the change of Yin and Yang in the universe and the infinite movement of nature. The ancient thinking mode of "Taiji Diagram" has also been reflected in the entertainment project of Go.
