Cheng Yizhi works as an employee in a dry goods store. Over the years, he has been almost an agent in the store, responsible for all affairs management, whether it is to calculate money with goods or to receive consumers. Mr. Chu hardly leaves the store at ordinary times and is obsessed with betting on horses.

Cheng Yizhi is tired of working for boss Chu to make money, and wants to work in a big store run by boss Xu. When he went to the recruitment interview, he took out a small abacus, calculated the money skillfully, and finally introduced himself briefly and described his situation smoothly.

Whenever he has time, Cheng Yizhi goes over the wall to copy the materials in colleges and universities. The security guards in colleges and universities all know Cheng Yizhi. At that time, the security guard urged Cheng Yizhi to leave the public library.

The security guard thinks that Cheng Yizhi is just an employee, so it doesn't matter if he copies more materials. Later, if he was killed by a part-time job, Cheng Yizhi refuted the security guard. He thinks learning is very effective.

After leaving the campus, Cheng has also become a beautiful college student, and Wu suspects that there have been many theft cases in colleges and universities recently. Wu suspects that Cheng Yizhi is a thief.

Cheng Yizhi had to check Wu's carry-on baggage, which contained only books. Wu apologized for misunderstanding Cheng Yizhi. She found that Cheng Yizhi's handwriting was very good, and that Cheng Yizhi was very interested in social economics, so she suggested that he could come to colleges and universities to listen to famous teachers after Cheng Yizhi. After school, Wu and her father go to the theater to watch TV plays. Her father and daughter are talking and laughing, and they are happy.
