serving as representative examples of the early PRC international postal system. During the 8th Postal Tariff Period (1 January 1955 - 31 August 1956), the aerogramme rate was 38 fen, and in the 9th Postal Tariff Period (effective from 1 September 1956) it was adjusted to 35 fen. Six of the items are international aerogrammes and remittance letters, most uprated with R series issues and bearing “PAR AVION / 航空” markings, addressed to destinations in Southeast Asia and Europe, including two remittance letters with original contents relating to remittance correspondence, vividly reflecting the realities of overseas Chinese communication. Also included is one airmail cover sent to Malaya. Collectively, the group illustrates the structured operation of the PRC postal system during the 8th–9th tariff periods, when aerogrammes and airmail letters coexisted, providing valuable reference material for the study of mid-1950s postal rate reform, route transit, and overseas Chinese postal exchanges.
