1. Climate problem: Hainan is located in the south of the Tropic of Cancer, so the whole province is in a tropical monsoon climate, with a long summer and no winter all year round. The summer temperature is between 23 and 34 degrees, and the average winter temperature is between 12-2 1 degree. Hainan is located in a low latitude area, so the sun is stronger and the ultraviolet rays are stronger. It is ok to come here for the first time.
You don't need to bring anything special, just what you should bring in your freshman year. Usually you just have to get dressed. I suggest you only bring summer clothes, spring and autumn clothes, winter cotton-padded jackets and the like. You can take some summer towels and quilts home for use. They are sold at school, but the price is higher and the quality is not as good as that at home. There are some necessary daily necessities.
3. How do you say this question? I think there are chaotic places everywhere, chaotic places. Don't worry, the security of Hainan University will not be chaotic, and neither will Hainan. Haikou is also a relatively safe city.
4. I am from the School of Economics, and I don't know much about the QQ group of the School of Information. You can wait until you report for duty, there will be brothers and sisters coming to see you, and there will be a hometown association or something.
Haidian Campus of Hainan University is just above Haidian Island, so it is close to the sea. The better scenery is to walk about 200 meters north from the east gate of Hainan University, but pay attention to safety.
I hope you have a good time in college.
