A Traffic Jam

April 4 is Tomb-sweeping Day, so we had 3 days on vacation. Because the chemical midterm was just over, I decided to back home. Even after two weeks, I had the biology midterm. I didn’t study it anymore. I wanted to back home on Thursday night. For that, I can’t go on duty as a volunteer on the hospital. I took the bus on 7:00 pm. It usually spends 4 hours arriving at Tainan. However when I was at Tainan, the time was 1:30am. Because too many people wanted to sweep tomb, the traffic jam happened.
