franked with seven 4 fen Dr. SYS Basic stamps overprinted in blue with “Tsuntan,” making a total of 28 fen, tied by Yunghingchang (agency) cds, and arriving Chungking on Jun 26, 1949. The franking correctly pays the domestic double registered rate of 28 fen (in effect from Apr 29 to Jul 31, 1949). This cover was accepted at a subordinate postal agency, and the stamps used - overprinted “Tsuntan” - were not issued by the local office or its postal district, but originated from another district, representing a highly unusual example of cross postal district/local post office usage during the Silver Yuan period. Under normal regulations, stamps were restricted to use within their issuing district; such cross usage reflects the practical breakdown of currency control and the gradual relaxation of postal administration during the turbulent conditions of 1949, carrying important institutional significance. According to current records, such cross-district usages are exceedingly rare, and this is the only known example prior to the abolition of the Gold Yuan system (before Jul 1949), of outstanding chronological and rarity significance. It vividly demonstrates the exceptional operational conditions of the local postal system in the early Silver Yuan period, and is of major postal history and exhibition importance.
