Why is there no official seal of "The State Intellectual Property Administration of the People's Republic of China" on my patent application acceptance notice?

For patents applied electronically, you will receive the "Notice of Acceptance" through the electronic application system after the application is accepted, but this does not have an official seal.

The stamped acceptance notice must be sent in paper form through the electronic application system, and then you will receive it after a few days (registered mail is relatively slow).
