A blue sky in Beijing does not mean it is a lovely day and kids can play outside with no harm. I frequently check the air pollution index and realize it is difficult to see the pollution. When their is yellow fog outside, you know to be careful and avoid outdoor activities. But a lovely day like today (May 10) surprisingly shows me pollution level 3 (116 mg PM10 per cubic meter). Nevertheless a day below index 150 count as a 'blue sky day' by the Government - a success in environment protection. Different countries different standards.
