Yangguanping Dike

　　Yangguanping Dike is located on the road from Jingxin to Fangchuan. Historically, Fangchuan was like an “enclave,” with two “isthmuses” between Fangchuan and the inland area. The narrowest section at Yangguanping was washed away by the Tumen River in 1957, so local residents had long relied on traveling through Russian territory to reach Fangchuan. In August 1992, the government invested 5 million yuan to construct the Yangguanping Dike. Through stone excavation and river filling, as well as earthmoving and road construction, a dike road was built on the Chinese “territorial waterway” of the Tumen River. The dike is 888 meters long and 8 meters wide, built by filling the river with bluestone.
