Can foreigners who were sent back to China in China (married in China) come back?

It is unlikely that many people will not be able to return to China just because they have committed crimes in China or have a bad record.

Even if you have a family, it is useless to have children. Many people marry foreigners abroad, because foreign spouses have bad records, so they can't come to China. Sometimes the embassy can't find their passports or numbers and can't get visas, but all the ports of entry have blacklists of this person. It can't be washed out, and it can only be washed in batches after 5- 10 years. It's no use looking for anyone Unless you know.
