Who are the immigrants who earn money from China people with foreign nationality?

There is nothing wrong with people of foreign nationality doing business in China to make money, provided, of course, that they operate according to law and pay taxes according to law.

From an economic point of view, any business, as long as it is not coerced, is theoretically a win-win situation.

So foreigners come to China to do business and make money, but they also pay wages, increase employment and pay taxes. There's nothing wrong with that.

If real foreigners come to China to do business, we welcome them. Then why can't people who have immigrated and become foreign nationals? Do we want a person to emigrate and join a foreign country, and he will immediately close all his factories in China, cancel his company, fire all his employees, and then leave China with money? What are the benefits to China's economy?
