If you are a government employee and have official documents that require the signature of the county magistrate, you can just submit them to the county magistrate's office or similar organization, and they will submit them to the county magistrate for his signature.

If you are an ordinary citizen and need to do something, you need the government’s consent. You only need to submit an application to the appropriate agency.

In fact, this is true not only of the government but also of the companies. Each department has documents that require the signature of company leaders and can submit them to the leadership office, where staff will hand them over to the leadership for approval.
