Li Weiguo, who was often bullied by his peers, was beaten and scolded by his mother Wang Caixia and made to wash clothes and do homework at home because he did not come home for lunch. In the afternoon, Li Weiguo was peeped at by the girl next door, Yang Meili, while he was taking a shower. Li Weiguo was furious and used this as a threat to force Yang Meili to do his homework and wash clothes for him. In the evening, Yang Meili told her sister Yang Meixiu what happened during the day. Yang Meixiu took out a digestive tablet and tricked Yang Meili into saying it was poison and asked her to use this "poison" to control Li Weiguo so that he would not be bullied. Li Weiguo, who believed it to be true, was manipulated by Yang Meili's threats and out of anger, he injured Erdan from the same village and lost money. Li Weiguo, who thought he would be beaten and scolded by his mother Wang Caixia, was rewarded because Wang Caixia believed that beating a douche would make him look good. Erdan was furious after being hit in the eye. Erdan called on his fellow villagers to draw a clear line with Li Weiguo and united with his friends to scare away Li Weizhong who claimed to avenge Li Weiguo.
Erdan and his friends went to Zhuergou to pick mulberries and were beaten by several children from Nanzhang Village. They escaped in a panic. The depressed Erdan and his friends returned to the village.
