1. After the Third Plenary Session of the Eleventh Central Committee, China's reform and opening-up policy is essentially internal reform and opening-up.

Contract responsibility system for joint production (rural)

Enterprise director responsibility system (city)

For example, after the reform, the living standard and quality have been greatly improved, the enthusiasm of rural production has been greatly improved, and the number and types of agricultural products on the market have increased. We have been exposed to more advanced foreign technology and culture, and strengthened exchanges between countries.

2. Special economic zones

Initially, special economic zones were Shenzhen, Xiamen, Zhuhai, Shantou and Hainan, and were classified as China Special Economic Zones after 1979. At that time, the state gave the SAR the right to examine and approve import projects, the right to examine and approve personnel going abroad on business, the right to export foreign trade, the right to manage foreign exchange and other economic management rights, and gave a number of preferential policies in taxation, foreign exchange management, bank credit, employment and personnel entry and exit.

3. The above two reasons are indispensable. In fact, many people in other special zones also went to sea, but Shenzhen was more successful.

During the period of reform and opening up, with the prosperity of market economy, many people were dissatisfied with the status quo and turned to business, which is called going to sea.

The word "Xia" has a condescending meaning. Many people who went into the sea turned out to be government officials. They gave up the guaranteed employment system and engaged in risky business activities, which also showed a kind of courage. People have the name of "shopping mall" and "business sea" for the industries that businessmen are engaged in, so the saying of going into the sea is still in use today.
