Which city is good to settle in? Dalian, Zhuhai and Xiamen

I have lived in Xiamen for 3 years and in Zhuhai for 10 years. I haven't been to Dalian, so I'll just compare Xiamen and Zhuhai for you. Zhuhai is the best, it won't be sultry in summer (you must know the taste of sultry in Wuhan), and it's not cold in winter. In terms of development, Xiamen is good, and Zhuhai's economy is too poor, not only poor, but also the name of the special zone. Cultural atmosphere, Xiamen is good, Xiamen has a long history and cultural and historical accumulation. Zhuhai is a newly-built city after opening up, with no historical accumulation. You can see the difference from the architecture. In terms of people, Zhuhai is good. Zhuhai is an immigrant, not enthusiastic, but relatively polite and not exclusive. Exclusion in Xiamen is not very serious, but it is somewhat. On water and soil, the water and soil in Zhuhai is really bad, very hot, and people easily get angry, so people born and raised here have bad skin and can't compare with the mainland. I prefer the appearance of Zhuhai ten years ago, with few people, quiet and clean. In recent years, there are more and more people, and the city feels more and more dirty.
