What is the air like in Caofeidian?

Caofeidian is a land formed by artificial reclamation in shallow sea beach, adjacent to Tanghai wetland. There are no hills in Fiona Fang for nearly a hundred miles, and the air circulation is smooth, which is conducive to the dissipation of particulate matter and smog in the air. So the air in Hebei Province is better. However, with the introduction of large-scale petrochemical, power generation, metallurgy and other projects, air quality will decline.
