The physical training course had a format of recording the performance details of the participants who need to punch in and punch out each time they started a run. The male students had to run 20 times and the female ones had to make it 18 times per semester to succeed in the course. But, one of the students named Zhou was afraid if he would be able to complete the course successfully. Hence, he decided to alter the official records in order to show the mandatory number of runs per semester.
The pace of the game accelerated when the second student named Cao learnt about the activities of Zhou and offered him his assistance. Cao agreed to bring in other students as well who wanted to get their accounts altered. He used to charge around $3/€2/20 yuan.
This went on for about 4 weeks when the institute authorities learnt about it and handed over the two students to the police. In their statement to the police, the students said that they were aware of the fact that the act they are doing was wrong but they were somehow not aware that they were committing a crime.
