During the Qianlong period of the Qing Dynasty, the famous scholar Ji Xiaolan, who edited the "Sikuquanshu", once said: "All the principles and things in the world have been described in the books of the ancients. If they are written again now, they still cannot surpass them. There is no need to write more about the scope of the ancients." This is indeed a famous saying. If you look at the ideological and academic works written by scholars from all over the world today, they all pick up the wisdom of the ancients, and even, to emphasize, they are all words that the ancient Chinese have already said. Therefore, Ji Xiaolan never wrote a book in his life, but only compiled books - sorting out the classics of his predecessors and systematically classifying Chinese culture to facilitate the study of later scholars. His own work is only "Yuewei Thatched Cottage Notes" Just a book.

Because he relied on this attitude to learn, he naturally read a lot, and his understanding was deeper and more accurate than others. He made an eight-character comment on Taoist scholarship: "Comprehensive Luo Baidai, broad and subtle." This means that Taoist cultural thought includes the entire culture of China for five thousand years. "Extensive" means encompassing many things, and "subtle" means extremely refined and incredibly subtle.

However, Taoism also has great disadvantages. The techniques of drawing talismans, chanting mantras, swallowing knives and spitting fire have all become Taoist culture, as well as yin and yang, feng shui, fortune telling, medicine, martial arts, etc. Etc., almost all of them are included, and they all belong to Taoist scholarship. Therefore, although it is "combined from all ages, extensive and subtle", it has also caused disadvantages.
