1, with schools as the source.
Think back to whether you signed anything related to files when you graduated, especially a tripartite agreement with your company.
Or go to school to find the corresponding teacher, because not all schools will send the files away to see if your files are still in school. If not, find out where they were put by the school when you graduated.
2. Go to your talent center.
Generally, files are not kept after graduation, and the school may send them back to the place of origin, that is, the place where the household registration is located. If you have changed your household registration, you should refer to the location of the college entrance examination.
3. Where I used to work
You can check all the cities where you have worked, starting with your first job. State-owned enterprises and institutions are generally placed in units, and private enterprises are placed in talent centers where units are located.
4. The talent market where the school is located
It is closely related to the first one, because after you graduate, the school may store the student files in the local designated talent market.
If you don't have time to inquire yourself, you can also find a professional file service agency to help you inquire.
