What are postcards for?

A postcard is a card with an image written on it, which can be mailed directly without an envelope. Images can be photography, painting or design, and stamps with full face value must be affixed when posting.

There is an image on the front, the postal code, address and name of the recipient are written on the back, and what you want to say to the recipient is written in other areas. The advantage is that you don't need an envelope, but the disadvantage is that there is little space and no privacy. What is written on the postcard is public and can be seen by others. The content usually does not involve concerns about privacy, so it is called a clear letter. Postcard postage is cheaper than ordinary letters. According to the business description of China Post, ordinary people can print postcards by themselves, but they are not allowed to mark "China Post".
