There are always different opinions on the theme of "From Herb Garden to San Tan Yin Yue". The main difference lies in whether to criticize the feudal education system. 1. The theme is criticizing the feudal education system. The central idea is to expose and criticize the feudal and decadent private school education divorced from children's reality. Compared with the gloomy, cold, boring and stale reflection of the moon in the three pools, the life in Baicaoyuan is suitable for children's psychology, showing their broad life fun, and how it hinders children's physical and mental development. A similar point of view is that compared with the boring life of reflecting the moon in Santan, the free and happy life of Baicaoyuan shows the children's psychology of loving nature and pursuing their own happiness. 2. The theme is not to criticize the feudal education system. What runs through the full text of "From Hundred Herbs Garden to Three Ponds Printing the Moon" is a sweet and joyful memory and an innocent and naughty childlike innocence, which is the artistic beauty and charm of this essay. According to some subjective needs, the works of revolutionary writers and artists are bound to be biased with "gunpowder smell", and the content of criticizing feudal education is attached out of thin air, and the front and back of it are separated as a contrast, which not only destroys the overall harmony and unity of this work, but also destroys its poetry. Therefore, the theme of "From Hundred Herbs Garden to San Tan Yin Yue" should be: to express children's love for nature, pursuit of fresh knowledge, innocence and happiness through the memories of the beautiful life of the Hundred Herbs Garden and San Tan Yin Yue.
