Do you have to have foreign stamps to make stamps?

Objectively speaking, the source of votes should be considered. Special stamp collecting should be the collection of domestic and foreign stamps and philatelic products. But at present, in China, it is difficult for most stamp collectors to collect foreign stamps. So you can choose some topics that only need domestic stamps, such as "Sports in China", "Ancient Buildings in China", "Scenery of the Motherland" and "Children in China".
