There is a Songjiang martial arts school at the foot of Liangshan Mountain, which is close to the mountain and waters. The children here took the first step in their martial arts career in the place where 108 heroes played. On this day, there was a fierce contest in the training ground of the school. After several games, Class Three One was defeated by Class Three. Analyze the reasons carefully. The students in Class One are too naughty. Teacher Wang Li's gentle management style makes the students in the class disorganized and undisciplined, just like a mess. Finally, the school leaders decided to give Class Three One a new martial arts teacher. The arrival of the new martial arts teacher Li Yang has greatly changed the situation in the class.
