20 13 what's the air quality like in Taiyuan? Is it worse than Beijing?

The deterioration of air quality in Beijing is the last year or two. Personally, I think it has a lot to do with too many motor vehicles. The air quality in Taiyuan is mainly influenced by industrial enterprises. If enterprises can invest in environmental protection and energy-saving equipment, the improvement of air quality will be immediate. But motor vehicle exhaust is a problem that cannot be returned. There seem to be more than 5 million motor vehicles in Beijing, more than people in Taiyuan. Of course, there are more and more motor vehicles in Taiyuan, and traffic problems and air problems also exist. Due to the geographical proximity, the weather in Beijing and Taiyuan is almost the same most of the time, but the smog in Beijing has become more and more terrible recently. In a word, the environment in Taiyuan has changed a lot. Whether it can continue to improve depends on observation.
