1. Peace brings benefits, war brings losses

2. Good weather, favorable location, people and people

3. Harmony is the most precious thing in everything

5. Benefit brings long-lasting benefits, harmony brings peace. ——"Zhou Li Kao Gong Ji"

The "Zhou Li Kao Gong Ji" written during the Spring and Autumn Period and the Warring States Period describes the spatial layout of the construction of the royal city in the Zhou Dynasty: "The craftsmen run the country, and the area is nine miles. , there are three gates on the side. There are nine warps and nine latitudes in the country, and there are nine tracks on the left and the right. At the same time, "Zhou Li·Kaogong Ji" also records the land area, road width, number of city gates, and city wall height of cities at different levels according to feudal hierarchy, such as "capital", "imperial city" and "prince city". There are also discussions on the relationship between suburbs, fields and pastures outside the city. The spatial layout system of urban construction in the Zhou Dynasty described in "Zhou Li·Kaogong Ji" had a profound impact on the practice of urban planning in ancient China. "Zhou Li·Kaogong Ji" reflects that ancient Chinese philosophical thoughts began to enter the capital construction planning. This was the earliest era when ancient Chinese urban planning thoughts were formed.

The book "Zhou Li Kao Gong Ji" records the division of labor in various handicrafts. Many of them are related to arts and crafts and are important materials for studying the history of ancient crafts. The "Liu Qi" in "Zhou Li Kao Gong Ji" is the experience record of the proportions of copper and tin in the six types of utensils at that time. The reasonable preparation of the proportion of copper and tin not only gives full play to the physical properties of the appliance, but also makes the shape and appearance of the appliance more exquisite.
