In the spring of 1999, early spring in March, sometimes cold and sometimes hot, on the playground of Hongxing Middle School, the afternoon exercise just ended, and there were still ten minutes to class. A group of half-aged children were running wildly on the playground, playing, releasing their excess energy, on the football field paved with yellow soil, more than a dozen students gathered in the corner away from the teaching building. A thin boy was surrounded by the middle, lowered his head and said nothing, he was wearing a obviously thin school uniform, covered with mud, and his face was covered with bruises. It was obvious that someone had just beaten him and let the people in front of him push him, but his fists were clenched tightly, obviously he was not admitting his defeat.
