franked with a Yunnan Half-Value Silver Yuan Basic stamp, tied by Chaotung cds, with arrival at Chungking on Jun 5, 1949. This cover was sent under the Yunnan postal district’s half-value Silver Yuan rate system implemented from May 10, 1949, with the domestic letter rate of 12 fen correctly paid. The half-value Silver Yuan stamps were issued on May 12, 1949, making this a very early usage example. Recorded as one of the earliest known domestic covers under the Yunnan half-value Silver Yuan system, it clearly reflects the special postal rates adopted due to regional monetary differences, as well as the operation of inland mail services in the early Silver Yuan period, of significant postal history and exhibition value.
