The Education Bureau can't detain files. The Education Bureau has no right to detain files. You can consult with the Education Bureau first. If negotiation fails, the dispute can be settled through litigation. Resignation teachers must go through the formalities of personnel agency at the district talent exchange center with the certificate of termination of employment contract within 30 days. Archives are the basis for paying social insurance and handling retirement. You should open an account in the talent center as soon as possible, or there will be endless trouble. I can ask the original unit to handle the file transfer procedures at the same time as the original unit handles the resignation procedures.
