China was a society based on agriculture in ancient times. Agriculture was the most important position of the country, and commerce was the last. Therefore, the emphasis on agriculture and commerce has been suppressed and hit, which has become the unchangeable policy of almost all rulers in China for thousands of years. Businessmen, as commercial operators, are subject to corresponding restrictions and repression from the policy to the system, such as many restrictions on commercial activities, strict requirements on time and place, heavy taxes on businessmen, and the refusal to allow their children to take the imperial examination, which gradually led to the formation of a tradition of despising businessmen and taking business as their foundation.
