Li Qingshan's soul travels back to the great era of 1965. As a young teacher in the school, he was repeatedly squeezed by the third uncle Yan Bugui, and even the residential house he was assigned was blocked. From time to time, I have to be wary of the hatred and revenge of He Yuzhu, my love rival! A good person will be bullied by others, a good horse will be ridden by others! When Yan Bugui became arrogant and domineering again in the open class, Li Qingshan finally couldn't bear it anymore and kicked the unreasonable old man in public and slapped the stickman who made trouble in class. Aren't you, Silly Zhu, a jealous person? I've made you so sad today, Teacher Ran, let's get married! System: Is there any mistake? I have a flat system! Can you fish? Li Qingshan: I also want to fish, but among the choices you gave me, which one wants me to fish? All the beasts in the courtyard: I regret it!
