For most tourists, Hainan and Sanya can be equal. To Hainan is to go to Sanya, and there is no impression of the provincial capital Haikou. It is true that the scenery of Haikou and Sanya is very different. It takes less than two hours to take the high-speed train from Sanya to Haikou to experience the slow life of the city. Sanya is a tourist city, Haikou is the administrative, cultural, educational and economic center city of Hainan Province. Hainan University, the highest institution in the province, is located in Haikou City. Hainan University was founded in 1958. Now it has three campuses with a campus area of more than 5,000 acres and more than 37,000 students. It is the number one institution of higher learning in Hainan Province. The creation of Haida has created a precedent for higher education in Hainan Province. . University's campus is like a free and open park with beautiful scenery, full of tropical trees and flowers, and green all year round. Haidian Island at the northern end of Haikou City, there is no industrial pollution, fresh air, a 10-minute walk from the campus and a huge Baishamen Park, a campus surrounded by green. There are no crowds, there are some empty roads, and occasionally two or three students enter and leave the school building. The recent travels have made me like to go to the local market and school campus to see.
