Comrades who work at night in the early morning asked me if I knew about the earthquake. They felt a strong earthquake. During the earthquake, the bed was shaking, and there was a rumbling sound, and the water in the cup was shaking. My sister felt the earthquake while watching TV at home. She felt the residential building shaking and the LCD TV shaking. At that time, it was estimated to be an earthquake, and the time was 2011.01.21,23: 55. The earthquake center is Liangduo Town, Dongtai.
