My wife is Vietnamese, and she has a son in Vietnam. How can I bring her son to China?

It's hard for you to find the answer here, just call the government hotline! Or go to the police station and ask, and they will give you the correct answer. Not here. No one dares to say that he is right, because no one has encountered such a problem, and even if there is, it is different from you. Even if they are the same, the answers and solutions given by the local government are different. I think this problem is very difficult to solve, because the child is not of China origin, but an immigrant. Not many people have successfully immigrated to China since the founding of the People's Republic of China.
