BE careful!!

I woke up early in the mornig today. I could see out side throug window. I thought something was grotesque. Out side was too yellow. How it could happend? I finally noticed that it was yellow sand. I went out about 10 am, and I felt like absorbing dust, but I thought it’s trivial things. After I met my friend and hanging out around Ill-San, I felt somthing was wrong. I have a sore throat. I thought I spent onlt few time out side, but I was affected by yellow sand. I should have had mask to protect that. I heard weather cast said that this condition would continue this weekday. If you are easily get cold or have problem with throat, take maske.
