I would like to ask if there are any more comfortable cities in China than Chengdu, and which ones? (refuse to copy, only talk about personal experience)

The climate in Haikou is quite good. It is neither cold in winter nor hot in summer, but it is not as sultry as Chengdu. However, the cool breeze blowing from Haikou on a summer night is super cool. It seems that you are more interested in Haikou, a better-developed city. Compared with the cities you listed, Haikou is not as good as the city center, but I think Haikou people are very easy-going, if you are a foreigner who speaks Mandarin. That person's Haikou people must speak Mandarin instead of Hainan dialect, which is not as deep-rooted as the regional concept of Chengdu people. They always speak their hometown dialect, and their consumption level is average. I think it's similar to Chengdu, beauty. . . Most of the beautiful women you see on the main street are from the mainland, but southerners all have accents in Mandarin, so I'm afraid you will find it a little difficult to adapt.
