At the end of class, the students discuss the upcoming four-school competition. One of the students says that he has never dropped out of the top three in his grade, and that he wants to take part in the competition. The other student, Mr. Ming, disagrees, saying that he will not agree to participate unless the other student tells him otherwise. The two men discuss the possibility of the two students competing under the names of "sheng xu" and "zhan shao" respectively. The first student says that sheng is a smart student, and he believes he has the talent to compete in the tournament. The second student explains that he learned about sheng's talent when he solved a geometry question that he was asked by sheng. The student compares his answers to the answers of the other students, and concludes that the student with the talent is a bit better than the other.
