Arrived Nagasaki (30 Dec). Since the inauguration of Yunnan-Vietnam Railway in Feb 1907, mails from Yunnan did not pass through French Indochina PO. Therefore, this cover took the train PO and was sealed in mail bag at Haiphong for Shanghai. The time-consuming overland route was not needed. 1909.12.7 雲南府寄日本。大清第四版郵資片，加貼1分以合寄日本特惠郵資。12.27經上海清郵，12.28經上海日本客郵局。12.30抵長崎。自1907年2月滇越鐵路通車，寄自雲南的郵包不經印支郵局轉寄。故此封採用火車郵車，經印支海防郵包直接封發上海，不用走費時費力的內陸郵路。
