It is not very easy to see blue skies over Beijing at the moment. For days a thick smog has swaddled the capital and several other cities and while smog is not new to Chinese citizen, who usually jokes about the “disappearing buildings” and make light of the issue, this time the levels of pollution is dangerously high.
It also causes concern with the Chinese authorities, who take the problem very seriously. Beijing have prolonged its “yellow alarm” until Saturday this week.
