Why is the grass-roots coast the most valuable one for tourism?

Because the bedrock coast is most suitable for 3S (sea water, sunshine, beach sand) projects, it is rated as the coast with the most tourism value. The bedrock coast, also known as harbor coast, is represented by Sanya and Lingshui coast in the southeast of Hainan Island, such as the ends of the earth. The bedrock is a marine erosion landform formed by the impact of sea waves, which is characterized by steep terrain, tortuous coastline and rapid current. The typical landscape of bedrock coast is the collision between waves and cliffs.
