The quintessence school advocates the preservation of national quintessence, which can protect the country and save the country based on the understanding that national quintessence is the foundation of the country. Therefore, they defined "national quintessence" and explored the unique value of China culture from the organic connection of nationality, history, language, writing and region. Although the quintessence school has different specific definitions of "quintessence", they have one thing in common, that is, they think quintessence is a kind of "national spirit" or "national spirit", which is contained in the ancient legal system and literary heritage. Therefore, they devoted themselves to classical exegesis, textual research of historical classics and the study of language and writing, and regarded this as equivalent to the Renaissance in Europe, hoping to realize the revival of China culture with the revival of "ancient learning" in China as the starting point.
Although the quintessence school advocates the quintessence of the country and maintains the tradition, it has not lost its consciousness of introspection on traditional culture. They divided China's culture into "national studies" and "national monarch studies", and thought that "national studies" contained rich patriotic traditions, nationalism, democracy and freedom; "Xue Jun" is a tool used by rulers to publicize feudal superstition, fame and fortune, strict education and implement autocratic rule. Therefore, they made a fierce criticism of "Xue Jun". They also improved the status of pre-Qin hundred schools of thought, which had been suppressed and excluded since the Han Dynasty, in order to break people's respect for Confucianism and superstition of Confucius.
We should not only reflect on China culture, but also reflect on the essence of western culture. In their view, although western culture has made great achievements in conquering nature and created "material civilization", its utilitarian attitude has led to social evolution, industrialization, the contradiction between cultural values and moral rationality, the separation of material life and spiritual life, and the richness of material enjoyment and the pain of spiritual life. This is in sharp contrast with China culture. China people are not as good as westerners in material enjoyment, but they are much happier in spiritual life.
