Intro. Lin Wenqing, born in 1972 in a poor rural family, has not been taken seriously since childhood due to the concept of preference for sons, completed his studies with the support of his mentor Shi Deming, and has been deeply involved in the education of Zenjing Middle School for more than ten years, and has been awarded the "Excellent Teacher" many times. She has always taken exam-oriented education as the core, regarded student performance and admission rate as the only yardstick of career value, experienced changes in the education industry, the utilitarian transformation of colleagues, and endured the crisis of salary cuts and career substitutions after the introduction of AI teachers. After being implanted with a dark chip by the mysterious AI Yang Jinyan, it was once blackened, and the resentment of the injustice of reality was transferred to Ai Jingyi, and finally the original intention of education was found under the awakening of the friendship between teachers and students in the past, which is a typical epitome of the collision of traditional test-oriented education and the changes of the times.
