The role of the coppersmith in the film is the object of education. He is illiterate, but under the influence of four intellectuals, President Sun, Zhang Yiman, Kuishan Pei, he not only learned to read and write, but also learned a few words of English. However, the motivation of this "cramming" education deviated from the right track from the beginning-four teachers were worried that the scandal of airspace reimbursement would be exposed, so they quickly trained the police to pretend to be unnecessary teachers in Lv Deshui. Under teacher Zhang Yiman's Sleeping Clothes, a blank coppersmith absorbed the "modern civilization education" overnight, so that when the coppersmith's wife came to throw it at Zhang Yiman, generate, a coppersmith, became "revolutionary" in anger, his male dignity was awakened and his independent personality was ignited, which was also regarded as the power of education.
By this time, all four teachers had done what they thought was right, and the result seemed to be happy: President Sun maintained the normal operation of the school, and Zhang Yiman, Kuishan Pei gained more income. Unfortunately, they only thought of the beginning, but did not foresee the end. The coppersmith, the bud planted in the evil soil of abnormal education, showed a poppy-like ferocious smile. In the first half of the contest with four intellectuals, the coppersmith was obviously in an absolute weak position and became the object of his play. Both physically and mentally, he was deceived in all directions. However, once his "human dignity" is awakened by the enlightenment of knowledge, it is like Pandora's box. In the second half, the coppersmith "deals with a man as he deals with you", analyzes the situation to the point, skillfully forms an alliance with the special correspondent, and finishes the crazy counterattack against the intellectuals in the classroom. Intellectuals are vulnerable to new intellectuals. Sun Jia, the daughter of the headmaster, put forward a point: "If this goes on in the past, everything will only get worse!" The old saying that "good is rewarded with good, and evil with evil" actually applies to education.
