1 and after graduation in 2003, the registration address on the registration card is generally the place where the school sends files.
2. During the two-year job search period, if I and my unit do not come to file later, they will generally be transferred back to the original Personnel Bureau (prefecture-level or district-level).
Go to the above two places to find your personal file first.
4. After determining the file location, please ask the institution to issue a file transfer letter according to the on-the-job personnel.
I hope it helps you.
