What do you think of the immigrants in China now?

First, China has a large population and is not suitable for a large number of immigrants.

Second, China's legal system is not perfect in relatively developed countries, and it is easy to be used.

Third, maintaining unity within the country is the most important criterion. At present, the average education level in China is not high, and people are not clear about the concept of democracy (most people think that they have understood the essence of democracy without reading relevant books and materials). In this case, it is easy to be driven by outsiders, leading to social instability.
