The Beilun River, a boundary river, is situated in the eastern section of the China-Vietnam border. It originates from the Shiwandashan Mountains in Fangcheng, Guangxi, China, and flows southeastward. The river serves as a natural divider between Dongxing City in China and Móng Cái in Vietnam, before finally emptying into the Gulf of Tonkin.
Stretching a total of 109 kilometers, the lower 60 kilometers of the Beilun River form the border between China and Vietnam. Regarding the opening hours and business status, they are contingent upon the daily operational conditions.
