Since the main cause of air pollution derives from PM2.5 emitted from vehicles in the city, Beijing city takes measures for it. For example,
・Restriction of car use(some cars can run the city on odd numbers' days, the others can on even numbers' days)
・Urgent construction of subways
・Planting millions of trees
・Staggered commuting hours
・Suspension of factories around the city
Despite these policies, air pollution hasn't yet been improved dramatically. polluted air blowing from hundreds kilometers covers the city, which depends on weather.
As London in the Industrial Revolution, Beijing will be famous as a fog city for the time being.
