The difference between commemorative stamps and scenic datestamps

Landscape datestamp is to narrow down the famous local scenery to a limited area and promote it by mail. The material is generally steel, the date can be changed, and it is stored in the scenic spot post office.

Commemorative stamps are usually made temporarily to commemorate an event. These materials are usually made of plastic. If there is a time and place for lettering (the name of the post office), tickets can be sold. If there is no engraved time (strictly speaking, it is called commemorative stamp), the time cannot be changed and tickets cannot be sold.

China Post has clear and strict regulations on the types and specifications of stamps, but it is not so consistent in the specific implementation.
