First of all, let us talk about the beautiful beaches of Hainan. Hainan has many famous beaches, such as Sanya's Yalong Bay and Haikou's Holiday Beach. These beaches are wonderful for viewing the blue sky, white clouds and clear water. We can enjoy sunshine, sand and waves on these beaches, full of nature's grace.
Next, let's talk about the exciting tropical rain forests in Hainan. Hainan is home to a variety of forests, including the famous Wuzhishan National Nature Reserve.
