The Directorate General of Chinese Soviet Posts was founded in Ruijin on 1 May 1932. The first stamps were designed by Huang Yaguang and printed lithographically by the Printing House of the Ministry of Finance in Ruijin. White paper or newspaper was used. They were imperforate, and denominated in the Chinese Soviet silver-dollar currency. They are fairly rare, and sought after by collectors. There are also many forgeries and bogus issues imitating early stamps from the communist areas.
