Which is the most livable second-and third-tier coastal city in China?

Speaking of coastal cities, we northerners will definitely think of Qingdao, Weihai and Yantai. In fact, for my personal feeling, Qingdao is still a very good livable city, because it is cool in summer and close to the sea, and some of its seafood and local folk customs are simple, so people living here are very comfortable. Sometimes we should think about it. In fact, for second-and third-tier cities, Qingdao is the first choice as long as it is near the sea and the local economy is good.

I have also been to Qingdao several times, and its local beaches are also very good. In addition, there are several scenic spots. In fact, it may be a little cold to go to Qingdao at this time. If anything, I think it's good to go to that place in summer. Because the environment in that place is better, plus there is no smog, and then it is very clean, so some middle-aged and elderly people living in Qingdao are in very good health.

Then Weihai. The city streets in Weihai can be said to be very clean, because that place is really good and the air is fresh. The local elderly are hardly sick, because there are too many negative oxygen ions in the air. It is really different to come here for recuperation or stay for a while. I stayed in Qingdao and Weihai for a while, but when I returned to the inland, I felt that the local air was also very bad, or my breath was a little stale.

If northerners are given a choice, I think most people go to Qingdao, and many people go to Weihai. Some people may think of Qinhuangdao, but I think Qinhuangdao is a coastal city in the inland Bohai Sea, and it may still have some disadvantages compared with Qingdao, so most people will choose Qingdao.
