If I want to emigrate and meet all the requirements of the other country, will I still be restricted by the laws of China before emigrating?

Yes, if you have one of the requirements of the country where you immigrate: no criminal record, then the possibility of being put on file when you enter or leave the country is zero. However, if you are a public official or a member of an important organ, you may still be restricted from leaving the country. Therefore, you should go to the entry-exit administration department with valid documents to check whether you are restricted from leaving the country.
