Blue skies are not an occasional luxury

BEIJING, TIANJIN AND HEBEI suffered from heavy air pollution from Tuesday to Thursday, with smog covering the whole region. Thepaper.cn comments:

One after another, people made bitter jokes about the smog, which has surprised people as such days seemed to belong to the past.

The number of smoggy days last year dropped by 18.1 days compared to in 2016, and many people, including many officials of the Beijing municipal government, said that the smog would no longer be as bad as it used to be.
