In ancient times: public land was rented but not taxed. Markets and shops were not taxed. Customs were checked but not levied. The forests, hills, rivers and marshes were visited at regular times but not prohibited. The land of the gui was not taxed. The people's labor was used, but not more than three days a year. There was no porridge in the fields, and no request for graves. The Sikong held the measure and measured the land, and the people lived in the mountains, rivers, marshes and marshes, and the four seasons. The distance of the land was measured, and the work was done according to the people's strength. When commanding the people: the old people were given the work, and the strong people were given the food. The talents of the people must be made according to the cold, warm, dry and wet weather of heaven and earth, and the different shapes of valleys and rivers. The people living in the land had different customs: hardness, softness, lightness, heaviness, slowness and speed were different, the five flavors were different, the tools were made differently, and the clothes were different. Improve their education, but do not change their customs; standardize their politics, but do not change their suitability. The people of China, Rong, and Yi, all have their own natures, which cannot be changed. The people of the East are called Yi, who have hair and tattoos, and some do not eat cooked food. The people of the South are called Man, who have carvings and patterns, and some do not eat cooked food. The people of the West are called Rong, who have hair and fur clothes, and some do not eat grains. The people of the North are called Di, who wear feathers and live in caves, and some do not eat grains. China, Yi, Man, Rong, and Di all have a safe place to live, a harmonious taste, suitable clothes, and tools. The people of the five directions do not speak the same language and have different tastes. To reach their aspirations and communicate their desires: the East is called Ji, the South is called Xiang, the West is called Didi, and the North is called Yi.
