How many foreign immigrants in China have been naturalized in China?

Too many. Life in China is really good. Many foreigners want to immigrate to China. But the China government will not give them so many opportunities.

In fact, things are rare now! There are not many foreigners, and China people will call them foreign guests when they meet them and treat them well, so they want to stay in China, although there will be so many people taking the TOEFL in Chinese. However, if China really opens its immigration policy, more than N foreigners will immigrate to China, and China people will not be so fresh to them, nor will they be as kind to them as before.

If you have been to those multi-ethnic countries, you will find that they all reject immigrants. Only in that country can there be racial discrimination.

Therefore, it is correct for China not to adopt immigration policy. Foreigners will only pay attention to us if they want to acquire China citizenship and can't get it.
