Is it as difficult for Americans to stay in China as it is for China to stay in the United States?

It's really difficult for China people to go to the United States, but if people have already arrived in the United States, it's easy to stay there.

It is easier for Americans to come to China, but after six months, their visas can only be extended twice, each time for one month, so they must leave the country for eight months at the longest. Moreover, China has a hukou system, so it is difficult to stay. . . Ah. . You can marry a beautiful girl and stay. .
