Card characteristics

Postcards are printed with a postage map (or marked with a frame to indicate the location of the stamp) and the format of the recipient's address and name on the front, and the back is used to write the communication content. Postcards are generally printed and distributed by the national postal department. Postage maps include printed postage maps and unprinted postage maps (postcards printed with postage maps are called postage postcards).

Other non-postal departments can also print postcards, but not with postage maps. Unprinted postcards include ordinary postcards, commemorative postcards, art postcards, military postal postcards and New Year postcards. The first postcard in China was issued on 1897 after the official opening of Daqing Post Office.

There are two kinds of colored paper in general circulation: direct sign colored paper and carbon paper colored paper (signature to pattern are printed matter, which are mostly used for various special gifts and are also sold at different prices).
