Yes, it's true. Shanghai has the most polluted air in the world, so I would not advise you to move to that city if you are not indifferent to your health. My friend moved to Shanghai 10 years ago, and now he has been diagnosed with lung cancer, and now he is on the verge of death. But whether the dirty air of Shanghai is to blame, I do not know. I am considering that my friend has never smoked in his life! And I know that many people suffer from lung diseases in this city. And you also have small children. I would not risk it on your side and would think about moving to another town. For example, the cleanest air in the world is in Australia. I think it's great to live there. I'm thinking about moving to this country myself.
