This is an emergency! ! ! ! Excuse me, if you have a passport in Japan, you will be sent back to China because your visa has expired. Is there a record of doing political review in China?

As long as they don't check you at immigration, they don't know anything.

If your job doesn't require you to leave the country, they don't have time to go to the immigration office.

They are not arresting criminals, so they won't stare at you.

Moreover, not everyone has access to immigration records. If you are not the director of immigration, you can't know the reason for your return to China. Don't worry about this.
