The relationship between China Chess and Zhouyi?

Modern China chess was formed in the late Northern Song Dynasty. It was based on the Eight Eight Yinqi in the Tang Dynasty, and was finally shaped by the popular Yi-ology and Hutuluo thought in the early and middle period of the Northern Song Dynasty. Harmony and Luo Zhixue are another cosmological model based on the "innate" Yi-ology. It uses numbers and figures to represent everything in the world, and uses the congenital 64 hexagrams and round charts to simulate the movement and change of the world, so it is also called "cosmic algebra". Generally speaking, China's chess design is often based on the thinking mode of the universe as a whole, including the unity of heaven and earth, heaven and man, and always emphasizing the principle of "Yi" in Zhouyi, which is dialectical and changeable. Therefore, when the number of Heluo increased, it was quickly used for the transformation of chess. Originally, the August 8th Bureau of Yin and Yang was divided into sixty-four hexagrams and nine lines vertically and horizontally, but the number of "river maps" was ten, so one more line was drawn on the August 8th Bureau of Yin and Yang to form ten lines to meet the requirements of the number of river maps, and a "river boundary" was added between the two sides to show that it originated from the river map. The number of Luoshu is nine, and the "Nine Palaces" since the Han Dynasty are also regarded as Luoshu, so they are also called Luoshu Jiugong. Jiugong was directly joined in the chess game, and as the base camp of both players, it was occupied by generals and literati. Because the median "five" in Jiugong symbolizes the coordination of all parties or the supremacy of the monarch. Early chess players all lived in five places, and only retired to one place after playing chess, symbolizing the beginning of the struggle for the world. Korean chess still retains this method.

The concepts of river map and Luo Shu entered the chess game. At least in 1055- 1075, when Cheng Hao wrote the poem "Xiang Xi", the poem said: "The Chinese army is heavy on all sides, but it is light outside the river." China's army has eight sides, that is, the "five" generals in Jiugong, so there are eight sides, indicating that there are Jiugong in the bureau; Step by step, people crossing the river can eat children sideways, indicating that there is a river boundary. In addition, it also implies that the chess pieces of Yin and Yang in Tang Dynasty can eat their children obliquely, which was inherited by Mongolian chess and chess, but lost in China chess.

Because in 1988, China added the river boundary and Jiugong to Yin-Yang chess, which was no longer suitable for playing chess in Yin-Yang chess, so he omitted Yin-Yang chess and arranged it at the intersection instead. Therefore, it was shaped into a modern form of China chess. However, it still retains the basic methods of Yin-Yang chess in Tang Dynasty. For example, an elephant walks three steps obliquely (that is, across nine hexagrams), a horse walks two steps obliquely, and a car walks straight without any distance. But generals and scholars are imprisoned in the ninth house.

I hope it helps you, hehe,
