From Christian Science Monitor:
Wednesday was a “blue sky day” in the Chinese capital.
But whether that has anything at all to do with the new traffic restrictions that the Beijing government imposed this week seems highly doubtful. There may be less smoke, but there are just as many mirrors when it comes to presenting pollution statistics in China.
A “blue sky day” in official parlance means a day when the Air Pollution Index is below 100, indicating that the air quality is “excellent” or “good.” It doesn’t necessarily mean you can see the sky, or even the clouds; nor do Chinese definitions of “excellent” and “good” match international ones, but you can’t be picky when you live in Beijing.
