Because China is a political economy. Foreign countries are market economies. So in China, politics comes first, and the exchanges in China are directly owned by the State Council. How can I change it into a company system? It's changed to a company system. The company is a legal person organization, and legal persons have to make money. For money, everything is dark and messy. The quality of China people has not reached the point where they can do things well and make their food bigger before they consider their own interests. . . Foreign countries are different, and their legal systems are sound. If something goes wrong, there is legal protection. China didn't. This is the fundamental difference.
