Longjing

The influx into the Chientao (間島) of Corean farmers, hunters, and trappers had long been a burning question before the Governments of China and Japan finally agreed by the Chientao Convention of 1909 or China-Corean Frontier Agreement to recognize the Tumen river as the boundary between Corea and China, and to open Lungchingtsun (龍井村) along with three other places to foreign residence and trade. A Chinese Custom House was accordingly opened here on 1st January 1910, but was made subordinate to the Hunchun (琿春) Customs.² It remained in this subordinate position till July 1924 when the head office was transferred to Lungchingtsun,³ while Hunchun—at which in accordance with the Manchurian Convention of 1905 a Custom House had been opened on 27th December 1909—fell into the position of a branch office. The reason for this deposition of Hunchun was the advent in 1923 of the T’ien T’u (天圖) light railway which running through Lungchingtsun to Yen Chi Fu (延吉府) connected both places with the frontier district of Kaishantun, and thence through Kainei (Hui Ning 會甯) to the Corean port of Seishin.
