What kind of countermeasures do citizens have for smog weather?

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.
