Yes.
If the person in charge of the unit has a party branch, please ask the party branch secretary to sign. If you cannot find the party branch secretary, you can also use a seal, that is, just add an official seal. The civil service examination registration recommendation form is usually signed by the individual; usually stamped by the unit, but it is best to have both signature and seal, just in case.
For fresh graduates to apply for civil service, the application recommendation form must have the seal of the Academic Affairs Office. Some units will keep your application recommendation form during the qualification review before the interview. It has just been a holiday, and school teachers may not have an official holiday yet. It is recommended to contact the school for stamping.
