It stopped raining

Weather in Shanghai can change completely within hours, last two days lots of rain with a cold wind. But today warm and an exceptional blue sky (most days there is a grey or even yellow cloud of pollution over the city) the rain must have cleaned the air for at least some hours.

Not that I could enjoy it with an office without windows and coming home when it is already dark. I could just find the time to take this picture with a ? clear? blue evening sky.
