Xingxingxia is located in the eastern part of Sinkiang, near the border with Kansu. It is a strategically important location as it is a key route for entering Sinkiang from the Hexi Corridor. It has long been known as the first vital gateway town in eastern Sinkiang. During 1920s, various warlords stationed substantial military forces in the area, leading to strict communication and inspection regulations. All correspondences, regardless of its nature, had to be examined and stamped by inspectors. In this stationery card case, the sender, "Shun Fa Foreign Company" was a commercial entity run by Germans. While it appeared to be engaged in trade, it was actually involved in collecting intelligence and information gathering. This gave it significant influence in the governance of Sinkiang during that period.
