Why does the weather forecast always show that the air in Fushun is better than that in Qingdao?

Because there are inhalable particles in PM2.5, smog often appears in Qingdao offshore. Even if there is no smog, there are tiny water droplets in the air. These water droplets are regarded as pollutants and classified as inhalable particles. People who often go to Qingdao know the Qingdao tide, and it is precisely because of this that they will come close.
