Can the teacher's thesis award certificate be reissued? In Jinhua area, the prize was won by the paper of Jinhua Teaching and Research Section, because the certificate was not obtained by changing schools.
The award certificate should not be reissued, because you won the award on behalf of the teachers in the school before you left, not on behalf of your current unit.
As you said, you can only negotiate with the original unit to get the license, or ask your former colleagues to get it for you, at least take a photo for you to copy or print in color for later use.
Good luck, please accept it if you are satisfied.
