An accident grants ordinary person Lu Qian special assistance. He once brought a class to brilliant results in a short period of time, but faced questioning from some parents and was forced to leave his original position. Putting aside his past honors, he takes over a class with a weak foundation. The students in the class each have their own troubles, and their study state is relatively poor. Lu Qian patiently observes everyone's characteristics, teaches students in accordance with their aptitude, discovers students' specialties, helps everyone build confidence, and fills in study shortcomings bit by bit. The original class, which used to have good grades, slowly reveals problems after he leaves. Lu Qian accompanies the students attentively as they grow, proving that as long as the right method is found, every teenager can break through themselves.
