Qingdao and Dalian: Comparison of air quality and water quality?

Air quality changes from time to time and is directly related to weather conditions. If Dalian and Qingdao are foggy and cloudy, and Beijing and Shanghai are sunny, it is possible that Dalian and Qingdao are not as good as Beijing. But this situation is not much. I have used mobile phone software to observe the pollution index of Beijing, Shanghai, Dalian, Qingdao and other cities for a long time. Dalian will be relatively better, but it is not excluded that it will reach nearly 200 in some days. It can be seen that the national air quality is worrying! I dare not say more about the water quality. I have no right to speak without investigation. Dalian has now become a chemical city, and the air and water quality are declining.

Dalian and Qingdao are actually very similar. Whether it is suitable for living depends on personal preference. Go for a walk in these two cities and stay for a week each. I'm sure you will know.
