1. Reprint, and the stamp can be moved to the correct position through related technologies.

2. Buy a bottle of hydrogen peroxide, dip a cotton swab in the hydrogen peroxide and gently apply it to the place with the official seal. Be careful, otherwise the paper will be ruined if it is broken. Wait until the official seal is wiped off, gently wash it with a paper towel, and then re-stamp it.

of course, if it is not a very important document and the requirements for paper and handwriting are not very strict, you can use this trick. Find a small tool knife and gently scrape the place with the official seal. When the official seal is scraped off, gently stick it with a piece of tape paper, then flatten the paper and re-stamp it.
