20 16 what is the total number of days of smog in Shanghai?

According to the statistics of the World Bank in recent ten years, China has occupied 3-7 of the top ten cities of air pollution in the world. Shanghai is not among the top ten. It should be said that the haze weather in Shanghai is less than that in Beijing, Tianjin and Hebei, and Shanghai is close to the sea, and the air humidity is high, so it is difficult to form haze weather. There are about 100 days of smog weather in a year, sometimes it is only mild smog, which is not obvious, and there will not be too many severe smog weather, about ten days.

Controlling smog is not only a national problem, but also a problem of low-carbon life. Travel healthily, use less disposable goods, and save and recycle water. If everyone solves one degree of electricity every day, how much PM2.5 can be reduced. Therefore, we might as well choose energy-saving appliances. My home is decorated with five degrees and five constant air conditioners, which integrates heating, refrigeration and fresh air. 120 flat houses only use 20 kwh of electricity every day.
