Too hot Daegu is the hottest city in South Korea in summer. For this reason, most buildings in Daegu have fine air conditioners. These two make people in Daegu weak cold, and this is why I had a cold. When I leaved my house, I felt very hot even I wore a short T-shirt and a short pants. After I came in the library in my university, I felt cold in a few minutes. I can not take long and warm clothes in my bag to protect myself because of their weight. It was approximately 30'c out of the building, and 20'c in the building. I had to be on my bed yesterday because I had a headache whole day. Today I could not concentrate on my study because of the sinus cold. It's a bad paradox that I have a cold in hot summer.
