Qionghai: the house price is 8000- 14000 yuan; I have been here, too. The pace of life here is slow, comfortable and comfortable, not exclusive, with convenient transportation, an airport, complete medical facilities, beautiful food, a standard Shanghai town, good air and a seaside. The ultraviolet intensity is average, the public security is good, and the climate is neither cold nor hot. The coldest time is just long sleeves and a coat, about 10 degrees, and the coldest time is ten days before the Chinese New Year. Summary: Livable.
Beihai: Coastal cities have pleasant climate, strong ultraviolet rays and good air, but the consumption is a little expensive, the urban planning is reasonable (much better than Guiyang), and the housing price gap is also large, ranging from 4000 to 9800. I don't know about public security, and I haven't heard of it. Medical care has been completed.
Haikou: It's a good city, with prices ranging from 6,000 to 7,000 and more than 20,000. Ultraviolet rays are strong! Note that I get sunburned every time I go ... but I'll be fine if it rains. The climate is pleasant, the scenery is good, the air is excellent (for me, it is a paradise in Beijing), the products are rich, and the pressure of life is small. Even the college entrance examination is the same. I envy it. I don't have to go to the scenic spots ~ and seafood is very cheap ... and it is also a city suitable for living.
Dongfang: This is not bad. After all, it is Hainan. Delicious food, good scenery, good air, I don't have to say, absolutely good. Haikou is prosperous, and the east is similar, but it is more comfortable and lively. Haikou still feels like a big city, but depending on your hobbies, personally, I think the east needs to be developed ~ (compared with Haikou ~) by the way, the house price is 600-
For reference only, I have been to these cities in the past two years, and some places only took one day. This is my personal opinion. Remember to adopt it if it helps.
