The Sea Cloud collar extends from the north to 30 kilometers of coastline. In 1965, the Vietnam War broke out. Because of the geographical advantages of deep water and wide harbor, Dagang became the first place for US military to log in. For Americans who participated in the Vietnam War, the memory of Chinese beaches can be said to be quite difficult. It was also a place where American soldiers used to gather for leisure during the Vietnam War. Meixi Beach, the nearest to the central part of Dagang, is the most popular beach for tourists. Langang Beach, which stretches for 30 kilometers, has deep blue sea water and fine white sand with no pollution damage. It is known as the Golden Coast of Vietnam, so it is also called the Landscape Beach. China Beach has been recognized by UNESCO as one of the six fine beaches in the world in 1995.
