Reasons for attaching importance to agriculture and restraining business: 1. It is no accident that the policy of emphasizing agriculture and restraining business complemented the feudal system. Because the economic policies implemented by a country or regime are ultimately determined by its economic base.

2. The root cause is the reflection of the backward and closed natural economy and the inevitable product of the low level of social productivity.

3. Natural economy is the economic base of feudal countries. Agriculture is the most decisive production sector in ancient times, and the situation of agricultural production is directly related to the rise and fall of the country and people's lives. The state ensures fiscal revenue by collecting stable land tax. Building the country by agriculture will inevitably become the governing program of rulers of all dynasties.

4. Industry and commerce can't provide basic means of subsistence, which aggravates the loss of labor from the land and causes social problems. The policy of attaching importance to agriculture tightly binds farmers to the land and contributes to social stability.
