Shanggao Education Bureau won't give me the file, what should I do?

This kind of thing is troublesome. To negotiate with the school and the education bureau, the key is the personnel bureau. A colleague of mine, like you, moved across the state. She first looked for the school, opened the transfer certificate and seal, and then looked for the Education Bureau and the Personnel Bureau. Anyway, you have to get the transfer order before you can do anything else. Find an acquaintance to do it.
