Yeah. Beijing, man...
In late March we had snow. I can't recall which week but it was a Saturday because I was walking through it on my way to tutoring.
Four days later it was so hot I was sweating even without a jacket.
Then by early April it was snowing again.
If there was a sandstorm in there, that must have been during the two days I was in Shanghai because I didn't see it, but after living in "Gray-jing" for the past four and a half years, I'll buy it.
