There is no red ink and no red seal at home. What if I stamp it?
Signed and fingerprinted. In the absence of red ink and red seal, you can sign by handprint. But this can only be limited to you personally. Not enough units. As long as a unit exists legally, it is impossible to have no official seal. If there is no seal, the main person in charge of the unit will not sign for the time being, and can sign and affix the official seal of the unit immediately after arriving at the office of the unit.
