combination franking was still required by French Indochina Post
after 1902, probably until Oct 1902. Given the inauguration of
Yunnanfu Chinese PO on 12 Oct 1901, combination covers of Chinese
and French Indochina franking only existed for about one year. One

按李頌平《客郵外史》記載，印支郵局與在華法國客郵局不同，在1902年後仍需混貼。按存世例子推斷應維持至同年十月。另由於雲南省清郵於1901年10月12日開局，故混貼清郵及客郵票之郵件只出於一年時間。此為雲南寄國外，混貼印支票並支付國際郵資之存世三例之一。
