There are more and more immigrants in China, will it cause serious ethnic problems?

I don't think ethnic issues should be considered, but public security is the key, because there are a large number of foreigners living here illegally in China. China's economy is ok now, and there is nothing wrong with it. It seems that everyone can find ways to make money. However, once the economy declines and there are not so many jobs and business opportunities, if these foreigners persist, it will become a great security risk. Refer to Paris, France for details. This multi-racial and multi-ethnic city can't provide so many employment opportunities. Now everyone is afraid of himself and has become one of the worst big cities in Europe.

Dear friends, we must understand that any country and city has a certain upper limit of bearing capacity, and once it exceeds everyone's living standard, it will plummet. Different national cultures are different, and some ethnic groups are violent by nature and cannot be integrated.
