The comrades who worked the night shift in the morning shift in my freshman year asked me if I knew about the earthquake. They felt a strong earthquake. During the earthquake, the bed shook, there was a roaring sound, and the water in the water glass shook. My sister also felt an earthquake while watching TV at home. She felt the residential building shake and the LCD TV also vibrated. It was probably an earthquake at that time. The time was 23:55 on January 21, 2011. The epicenter of the earthquake was Liangduo Town, Dongtai.
