Yellow dust!!

I am a little sick. I have a sore throat. It might be from the yellow dust. there is this dust that comes from the Gobi Desert. As it floats on its way to Korea it picks up pollution and then becomes contaminated. Because China has cut down so many trees and is building so much, more and more dust gets to Korea. If the yellow dust count is over 300 you are supposed to stay in. The other day it was 900! So it's been pretty bad. Anyway, I think it's an interesting phenomenon and probably why I have a sore throat and runny nose.
Sometimes the schools even close because of the yellow dust.
