As weather gets warmer, nearly 200 beautiful swans flock back to the Daling River in downtown of Chaoyang City, Liaoning Province. A harmonious and charming landscape is formed with sunset over towering buildings and swimming, amusing, and flying swans. In recent years, with improvements in ecological environment and water quality, more migrating swans stop by here. These dynamic swans have a rest for almost a month here from the beginning of March every year and can be seen gathering together by citizens taking a walk right outside their homes.
