Sorry to tell you this, but hmmmm.
You see, Beijing is the one of the most polluted city in China, if
not, the world. To have a persistently clear blue sky in Beijing, a
blue moon must have appeared somewhere.
And one last thing, looks can be decieving. The picture might show
a clear blue sky, the citizens might be suffering from smog.
I personally dun want to stay in Beijing or Shenzhen, the air is so
unhealthy that I certainly dun want any lung-related disease.
