The "three flavors" in Lu Xun's private school "Three Taste Book House" referred to "books, wine, and tea", implying the trinity of culture and education. In the library, students not only needed to study classical literature, but also needed to cultivate elegant taste and accomplishment through drinking and tasting tea. These activities were considered an important form of cultural education at that time, which helped to cultivate children's comprehensive quality and etiquette.
