If you are a long-term pensioner, I personally suggest you go to Wenchang or Wanning on the East Line. The average annual temperature in these two days is around 24-26, which is very suitable for people to live in. The environment here in Hainan is good, so there is nothing to say. Hainan's air is the best in the country, and negative oxygen ions are particularly high. Moreover, its water quality is the best in China, and it contains potassium, sodium and magnesium plasma beneficial to human body. Drinking this water for a long time can improve people with bad stomach. If you used to stay healthy for the winter, I personally suggest you go to Wenchang or Wanning. Wenchang is the city with the highest humanistic quality in Hainan. Moreover, Wenchang's coconuts are particularly famous, such as Wenchang's coconuts and mangroves, which are very precious plants. Too cold or too hot will not grow and bear fruit, but only at a certain constant temperature in Wenchang. For example, if you take it indoors in the north, it won't grow. Suitable for the growth of plants and the fitness of human body. Moreover, Wenchang is surrounded by the sea on three sides and belongs to the tropical monsoon marine climate zone. A slight sea breeze blows every day, which is particularly comfortable. Wanning is called Little Sanya. There are many tourist attractions, including seven bays and eight islands, four gardens and three mountains, and the famous reservoir in Wanning. The water quality in Wanning is the best in the world. The average annual temperature in Wanning is 26 degrees, with no long summer and mild climate. The vegetation in Wanning Xinglong is the most in Hainan. So the greening is good and the air is fresh. Moreover, the state has invested more than16 billion to focus on the construction of Wanning City. So in general, whether it is winter health or investment, these two places are very good choices.
