Wanquan Liji Qingpi Forest

　　Covering an area of 16,000 mu, it was established in July 1980. The main goal of establishing this nature reserve is to protect the valuable Qingpi tree, a rare species of tropical forest in Hainan. The Qingpi tree belongs to the Dipterocarpaceae family, can grow up to 30 meters tall, with a trunk diameter of up to 1.2 meters. It has a straight trunk and bluish-gray bark, hence its name. The wood of the Qingpi tree is hard, durable, and resistant to moisture, making it an excellent material for constructing bridges and ships as well as crafting fine wooden items.
