Category: Chinese Stamps ■ Description Issued October 1945 in the Jin-Cha-Ji Border Region. Unissued Changchun edition, counterfeit Mengjiang (Mongolia) Sun Yat-sen and Martyrs stamp. With "tokashi" (watermark) Liberation Area stamps refer to a series of stamps issued by postal organizations in various revolutionary bases, liberated areas during the war against the Japanese army, and later in the various liberated areas during the Chinese Civil War, under the leadership of the Communist Party of China, over a period of about 20 years from 1930 to 1950, during the Chinese people's revolutionary war. Initially, these were only recognized as local stamps of the "communist bandits" and were of interest to only a small number of people. Today, they are valued as precious cultural relics and materials that tell the history of the Chinese people's revolutionary war, and are collected by enthusiastic philatelists (stamp collectors) around the world. Because they were issued under harsh conditions, constantly exposed to enemy attacks, or in situations where everything was burned to the ground, the remaining numbers are small, and there are areas where the whole picture has not yet been revealed. In China, research and investigation into Liberation Area stamps have gradually become active for about 50 years, and new discoveries are still being made, and Liberation Area stamps are even called a "treasure trove of the unexplored." ■ Condition Slightly dirty.
