A new term begins and the pupils and teachers of Li Ren School are back again. This is the first day, Shen Rong (Cheng Liping), a city girl, reports for work at the school. She is wondering how to get to the school when she runs into a young Chinese physician, Zhou Wenjie (Li Nanxing). Wenjie offers to show her the way but she makes her fall into the mud pool instead. Meanwhile, the pupils at Li Ren School still refuse to assemble despite repeated calls by the oldest teacher in the school, Kong (Liang Baozhu) and Tang Liren (Hong Peixing). The students only pay attention when a smart-looking teacher, Yu Qingfeng (Zhu Houren), appears. An overaged pupil. Zeng Jinmei (Zhu Leling), quickly greets him. Yu returns the greeting, not knowing that she has taken a fancy to him. When the students are assembled, the principal, Zhang Caiqin (Hong Huifang), walks onto stage to give a speech. She does not realise that her students are bored by it. Shen Rong creates a furore when she appears in the school hall, looking dirty and unkempt. Caiqin gives her a change of clothing before arranging for her to teach the Primary Three pupils. The pupils make fun of Shen Rong but she outwits them. SHen Rong's colleagues and pupils' parents find her teaching methods unusual and doubt her teaching ability. Shen Rong comes from a wealthy family. He widowed mother, Qian Zhuli (Jin Yinji), is fashionable and runs a beauty salon. She objects to Shen Rong going to a remote village to teach but fails to change her mind. The next day, Shen Rong discovers a naughty Primary Six pupil, Lin A-pei, bullying her pupil, Zhou Wenfang. She insists that A-pei apologises to Wenfang but he refuses, so she challenges him to arm wrestle with her. A-pei loses to her and has to apologise. A pupil, Wencai, finds bugs in his chair so he begins beating them. The noise distracts A-pei, who thinks that Wangcai is mocking him for having to apologise to Wenfang. He thus challenges him to fight. Shen Rong's confidence is shaken when she finds the pupils so unruly. When the villagers celebrate the ghost festival, she becomes interested. Hence, she decides to give teaching another try. On her way home, she discovers that A-pei and Wangcai are lovable in their own ways...
