Can China accept overseas immigrants?

No immigrants in China say so, only long-term detention. A foreigner has a China hukou for only one reason: he got married in China and the other half is from China. Second, people who have made special contributions to China strongly demand to become citizens of China. Third, dual international personnel with heavy ID cards and passports. Foreigners do not immigrate to China, but are detained for a long time. Generally speaking, they will leave China after a short detention of five years.
