Which one is better, Shenyang or Dalian?

I am from Dalian, so of course I prefer Dalian. Now studying in Shenyang, I personally think Dalian is more suitable to live.

First of all, the air quality in Dalian is good, and PM2.5 is generally excellent. Shenyang is generally heavily polluted and has more smog weather.

In terms of temperature, Dalian has warm winters and cool summers, with a small temperature difference between morning and evening. Shenyang is hot in summer and cold in winter, with a large temperature difference between morning and evening.

But the disadvantage of Dalian is that the prices are very high.
