Xiao Xiu’s mother died when I was four years old. The cause of death was a traffic accident. On her way home after buying dinner, the driver of the truck who was driving the car dozed off and ran into the pedestrian walk and hit her. It seems that she died on the spot. Xiao Xiu was a boy of the same age who lived near my home when I was in kindergarten. In his short, straight hair, I saw his tears flow like raindrops, I can see his deep sorrow.
