Matthew College is a famous school in the New Territories. Teachers and students are spared to fight for the upper reaches in a melting pot that is weak and strong. Lu Wenda (Lu Sir), a Chinese teacher and 5C class teacher, taught Chinese at the Matthew College for five years. In the same year, he set foot on the faculty for the sake of his life. He had the invisible pressure to build a family, take care of the two old people, and he longed for a long contract. In the iron rice bowl, the performance of the school has always been unsatisfactory. Not only has it not been promoted, but it has been repeatedly criticized by the school, bullied by the Chinese director Louis, and crowded out by colleagues. The previous student unions of Matthew College have always been the bag of elite classes, but this year there has been a dramatic reversal. 5C class Mai Haoxian (Sin Tsai) and Zhuang Zimin, two people and elite students became a raging fire, and a group of students who were labeled as losers by the school formed a prime cabinet "not old knight", and Lu Sir helped each other and successfully broke Monopoly is elected to the student union. The new principal, Liang Wenhai, plans to convert the school into direct capital in the name of guaranteeing the quality of admission and improving the quality of teaching. As the first graduate, Lin’s deputy school believes that direct investment is against the idea of running a school. I don’t want the school to become aristocratic, try to stop it, and let the long-term force force Lu Sir to serve her, together with the home economics department, music department, and training teacher. "Not a knight", against the direct-funded teachers including the Chemistry, Liberal Studies and Computer Science, secretly deducted Liang Wenhai.
