When Lu Xiaoyou was in high school, the class was divided into several cliques.
The rich girls' faction, led by Zhu Ti, was responsible for spreading rumors that Lu Xiaoyou slept with all the males in the school, stole things, binge drank, smoked, had abortions, and other gossip; Lu Xiaoyou's good grades were all because she slept with the male teachers for answers.
The bad girls' faction would block Lu Xiaoyou at the school gate, rob her of her pocket money, and tear up her textbooks and homework. They were in charge of beating Lu Xiaoyou once a week to vent their physical energy.
The bad boys' faction would stand by and watch while the bad girls' faction beat up Lu Xiaoyou, threatening her not to run away and to take the beating obediently.
They would use lighters to burn her hair, school uniform, and scream with laughter as they splashed Lu Xiaoyou with the dirty water used for mopping the floor.
