In the cold-chain logistics port of the Baishazhou large market, one merchant sold 1 or 2 smaller scales for crabs. After being spot-checked by the inspectors of the crab association, they were fined 3,000 yuan and were suspended for 3 days.

According to Yang Daoyi, president of the Crab Association, in 2007, there were 120 merchants selling crabs in the market. In the following two years, the merchants have been eager for quick success and the reputation of Hubei crab has been destroyed, and the business has become more and more dead. In 2009, Yang Daoyi took the lead to visit Jiangsu Province. The orderly market atmosphere of the local business has given the merchants a lot of inspiration. After returning to the Han Dynasty, Yang Daoyi organized a business association to set up a crab association and register it with the civil affairs department.

The association has formulated severe penalties for illegal businesses. After the introduction of the regulations, most merchants can self-discipline. In the past three years, only a total of more than 10 merchants have been punished and 4 merchants have been suspended for rectification.

A consumer said that if the wholesalers shoddy, the shortfall, the only disadvantage is the consumer, the market will return fewer and fewer customers, which will lead to a vicious circle. According to the statistics of the association, the daily average trading volume of crabs in the market has increased significantly before the establishment of the association. The daily turnover of crabs is about 300,000 kilograms per day.

In this regard, Zhang Jitao, associate professor of the College of Political Science and Public Management of Hubei University, believes that internal self-discipline in the industry is beneficial to the healthy development of the industry.
