No matter what the file is, it will not be lost in general. Because the flow of documents is transmitted through a private line.

If it is a student file, you can't find it yourself. You can try to contact your last graduation school and negotiate with the school. At least fill in the following materials: graduate registration form, student registration form, copy of academic report card and other necessary materials to prove your study experience in the last graduation school.

If the applicant wants to use it, remember to add a certificate of missing files (issued by the graduate school and handled through consultation).

If you didn't lose it yourself, you can check it through the following channels first:

Go to the archives of your graduation school first, check the transfer registration, and find the destination unit of file transfer;

Second, go to the destination unit to find the recipient to sign and register;

Third, if you follow this route, you will definitely find the final destination unit (place) of the document.

Fourth, when sending students' files, some places sometimes go to the talent exchange center of the local personnel bureau, and some places go directly to the branch office, and so on. If you can't find it, you must look for it in many ways.

5. If you haven't lost it, you can also instruct the forwarding unit to handle it until you are satisfied.

If in doubt, please consult the public education enterprises in China.
