Hainan Betelnut Valley Limiao Cultural Tourist Area is located in Ganshiling Nature Reserve at the junction of Baoting County and Sanya City. It is the first national cultural 5A scenic spot in China. The scenic spot is situated in the sea of areca nut forests with more than ten thousand pavilions and graceful pavilions, and in the tropical rain forest with towering ancient trees and vines. It has a long and mysterious history. With the rapid development of modern society, some historical cultures and national crafts are gradually becoming endangered and lost. The Betelnut Valley has carefully protected and preserved a number of traditional techniques of Li and Miao ethnic groups, which are on the verge of being lost, and the disappearing local cultural phenomena of Hainan.
