Lin Wan went back to his alma mater to open an all-you-can-eat buffet for five yuan, hoping to help poor students eat decently, but was reported by Jiang Zhe, the second-generation rich man, for "hurting their self-esteem." Under pressure from the principal, she upgraded the window to high-priced small dishes, causing dissatisfaction throughout the school. Subsequently, when Chen Yue, a poor student, fainted from hunger, the truth was exposed and Jiang Zhe became the target of public criticism. Under the pressure of public opinion, the school compromised. After Lin Wan proposed a public apology and Jiang Zhe's self-censorship and other conditions, the buffet was restored to 15 yuan with no limit, which not only preserved feelings but also established rules.
