The orientation of sitting facing south was inspired by Zhouyi, saying, "When you go out, you will know, and everything will know, and the southern divination will also be." In other words, gossip in gossip symbolizes light. When the sun is in the middle, it shines in the south so that everything can be seen. This is gossip representing the South. Therefore, the emperor deviated from the divination and sat in the north, facing the south to listen to world events, symbolizing facing the light and governing the world.
Therefore, Zhouyi Shuo Gua said: "The saints listen to the world from the south, rule the world from the Ming Dynasty, and cover all this." Ancient kings sat facing south after they ascended the throne, which was called "Southern King" or "Southern Emperor".
In ancient times, when monarchs saw their ministers, elders saw their children, and they all sat in the south, while courtiers or children stood in the south, that is, facing north. Therefore, referring to people as courtiers is called "Northern Rites". According to Records of Historical Records of Xiang Yu, Xiang Yu threatened Liu Bang to withdraw his troops by cooking his father. Liu Bang said, "Xiang Yu and I were both ordered to be brothers in the north. If I were Weng, I would cook Weng, so I am lucky to have a piece of it. "
It means: "Xiang Yu and I are both facing the north and Chu Huaiwang. We were brothers. My father is your father. Please give me a piece of cake. " Later, "North" also had the extended meaning of giving up, seeking surrender and seeking peace. Because humble young people face the north to visit their elders, worshipping people as teachers is also called "North". This point is proved by an example in the biography of Han Yu Ding Guo: "Ding Guo is to welcome the teacher to learn the Spring and Autumn Annals, hold the scriptures, and prepare for the northern disciples."
Sit facing south and conform to heaven. In ancient times, the south was regarded as supreme, while the north symbolized failure and submission. The king reigns in the world, the ninth five-year plan. The fifth soil behavior is yellow, and the soil lives in the center, symbolizing the unity of the country.
Contrary to the position of "South", "North" was inferior in ancient times. In ancient times, when monarchs met ministers and elders met humble teenagers, they all sat in the south, and courtiers or humble teenagers all stood in the south, that is, facing north. Therefore, "North" refers to the person as the subject, which is called "North as the subject".
It can be seen from the above that "south" is called the emperor's reign, because the concept of facing south is respected.
