these are representative examples illustrating the institutional development and rate adjustments of the early PRC international airmail system. The covers were addressed to destinations in Europe and Southeast Asia, all correctly rated according to the postal structure of “international surface postage plus airmail surcharge.” The group includes: a 1950 Shanghai–Singapore cover franked 9,000 yuan; a 1951 Shanghai–Switzerland cover via Prague franked 9,000 yuan; a 1953 Peking–East Germany postcard franked 6,700 yuan; a 1953 Peking–London cover franked 7,600 yuan; and an August 1955 Canton–Singapore cover franked 5,800 yuan. Together, the covers reflect the standardized operation of postal rates and international route divisions in the PRC’s airmail service during the early to mid-1950s, offering valuable material for postal history research and exhibition.
