Evolution of Suifenhe Ownership

Buji people lived in Suifenhe Valley in the Southern and Northern Dynasties, and it was renamed Mohong in Sui and Tang Dynasties. Dongning area may have belonged to Baishan system or No.1 room system at that time. During the Tang Dynasty, Dongning area belonged to the guest house of Bohai State. Lingbin House is an earlier administrative institution in Suifenhe River Basin. Modern historians believe that the government of the guest house was ruled in Shuangchengzi (now Ussurisk, Soviet Union). According to the excavated materials, Dachengzi Village in Dongning Town may be the seat of the Governor's Office in Bohai State. There are still guest houses in Suifenhe Valley in Liao Dynasty. After Koguryo perished in the Bohai Sea, nine cities were built south of the Hailan River. In order to fight Goguryeo, Liao also built nine cities. In the Jin Dynasty, the "T-shirt" road was set up in Suifenhe River Basin. Four years after Jin Zhenyou, Suifenhe River Basin once belonged to Dongzhen State. The Yuan Dynasty was Kaiyuan Road, Zhongshu Province, Liaoyang. In the Ming Dynasty, Jiang Bing established Wei in Suifenhe River Basin. Since the Qing Dynasty, Dongning area has been under the jurisdiction of Ningguta. After the Qing soldiers entered the customs, in order to protect the birthplace of their ancestors, most parts of Northeast China were designated as forbidden areas, which not only prohibited Han people from entering, but also prohibited Manchu people from entering, which led to the long-term desolation of this vast area and gave Russia the opportunity to invade. In the eighth year of Xianfeng (1858), China lost 600,000 square kilometers of land north of Heilongjiang in the unequal Aihui Treaty. In the tenth year of Xianfeng (1860), Eight-Nation Alliance captured Beijing, and tsarist Russia forced the Qing government to sign the Beijing Treaty, taking away 400,000 square kilometers of land east of the Wusuli River, making the lower reaches of He Sui a Russian river, the Hubutu River a Sino-Russian border river, and the Dongning area a border area. The territory of northeast China was continuously taken away by Russia in a large area, which forced the Qing government to realize the mistake of the ban policy and began to open the border ban and immigrate to the real border. At this point, the long-term desolate Dongning District has been opened up again. 1993, China and Russia once again demarcated the eastern border, and on the Hubutu River northeast of chunhua town in Hunchun City, Russia was included in 4.7 square kilometers of land in Hunchun, China.
