Historical evolution of Liuhe chess

Weiqi came into being in the Yao and Shun period in ancient China, with a history of 5000 years. Weiqi has a deep relationship with the Book of Changes and astronomy.

Wu Qingyuan believed that in ancient times, Go was a prop to study astronomy or almanac. The chessboard consists of 19 horizontal lines and vertical lines, and there are 36 1 intersections around Tianyuan. Wu Qingyuan thought it was used to indicate the direction, angle or season in ancient times.

In addition, ancient China believed that "one yang" was the root of life in an empty universe. From "one yang" to yin and yang, and then everything is formed. Weiqi has black and white pieces, so it must also come from yin and yang thoughts. Maybe it's also a tool for divination. In a word, the chessboard is the universe.

The center of the chessboard "Tianyuan" is called "Tai Chi" in China. In the words of the Book of Changes, it is the most primitive point from scratch.
