Originally, I wanted to stay in Dongxing for one night. It was not fun. Second, I was afraid that we would miss Xialongwan at noon the next day, delaying our journey. Vietnam was too uncertain. After dinner, walk along the roadside at will. Many shops are open on the first day of New Year's Day, but there are still busy here. There are no big buses in Dongxing. They are all small environmental vehicles. The doorway of the roadside trade building says "Sino-Vietnamese friendship, evergreen forever. " Walk a few steps to the Beilun River, across the river is Vietnam, look at the Dongxing Gate, there is also a bridge on both sides.
