The position of the Daqingguo No. 1 boundary monument is special. It is not only the symbol of the border between China and Vietnam, but also the starting point of the Chinese coastline and the starting point of the land boundary line. The coastline of the Chinese mainland starts from the Yalu River estuary in Dandong City, Liaoning Province, and ends at the Beilun River mouth in Dongxing City, Guangxi, with a total length of 18,000 kilometers. The Chinese land boundary line starts from the boundary of the Daqing State and turns northwest to the northwest. Then, at the mouth of the Yalu River, the Daqingguo No. 1 boundary is the intersection of the mainland coastline and the land boundary line. People who have religious beliefs generally have public places of worship. The religious sites of the Jing people in Guangxi are not temples, temples or churches, nor are they a mountain or a specific object. They are the Hatings in each village. They gather here and are here. The violin is a folk instrument popular among the people of the Jing people. Whether it is festive or slack farming, people should sing impromptu folk songs under its accompaniment. Because its pronunciation is very similar to the tone of the folk songs of the Jing people, the decorative sound is full of sing-like charm, so when accompanying the folk songs, the sound of the piano is mixed, and the two are integrated. As the Fangchenggang of the Sino-Vietnamese border, the people and culture of China and Vietnam exchange frequently here, bringing a unique charm to this border city. On the 10th and 20th of each month, the Chinese and Vietnamese seniors will come to each other's elderly distribution centers to bring talents to each other and add a different kind of excitement to the elderly.
