It is ridiculous to say that China doesn't have a blue sky and white clouds. Generally, the area with the best air quality in China is still the southeast coastal area and the area with the worst air quality is north China. Let's take Shijiazhuang city as an example. It is in the inland area and it has concentrated industries. Therefore, the air quality of the surrounding areas of Shijiazhuang ranked lower every year. The area with the best air quality is Hainan Island and many Chinese people buy real estate there for their retirement. Anyway, I believe that the United States has better air quality than ours, except for that the US is the most developed country in the world and the fact that the United States has almost the same amount of land as China, but it only has one quarter of the population of China has also made a great contribution to the air quality in the United States. In addition, I believe the air quality in Canada and Australia is also better than ours because China has too many people.
