From the outside of the Chaojian Bridge in Sanya, Sanya Bay is outside the boundary. The inside of the bridge belongs to the Linchun River. The Linchun River has risen with the sea and the river changes. In recent years, with the increase of Sanya's population, the Linchun River has also been seriously polluted. Linchun River Park is an open city park. In the dry season, the bougainvillea blooms very well, with dense flowers and a long duration of flowering.
