We´ve all heard it before: Air in China´s big cities is awful. A lot of Chinese put protection on their noses and mouths to filter the air.

To know when to put on protection and when not, there is an app, that tells you how dangerous the air actually is that you are breathing. Surprisingly Beijing´s air is alright today.  That´s due to the fact that there is a national holiday today and China´s Communist Party wants the workers to celebrate as well. So they turned off most of the factories surrounding Beijing. Quickly the air dropped to a nice blue number. No danger to breathe in – and out. Enjoy!
