Sinology, also known as Sinology or China Studies, refers to the traditional culture and knowledge of China. Chinese studies include China's ancient philosophy, history, religion, literature, customs, textual research, ethics, traditional Chinese medicine, agriculture, martial arts, geography, politics, economy, painting and calligraphy, music, architecture and many other aspects. The concept of "Sinology" came into being in the 1920s, when the trend of "Western learning spread to the East" was in full swing. Zhang Zhidong, Wei Yuan and others put forward the concept of "middle school" (Chinese studies) in order to oppose western learning, and advocated that "middle school should be the body and western learning should be used". On the one hand, they studied western civilization, and at the same time, they resumed the study of Confucian classics in the Han Dynasty. [4] Sinology, based on pre-Qin classics and hundred schools of thought's theory, covers a set of unique and complete cultural and academic systems, such as Confucian classics in Han Dynasty, metaphysics in Wei and Jin Dynasties, Neo-Confucianism in Song and Ming Dynasties, parallel prose in the Six Dynasties, poems in Tang and Song Dynasties, Yuan songs and novels in Ming and Qing Dynasties, and historiography in past dynasties. Hundred schools of thought's theory in pre-Qin Dynasty was * * * *, and there was no master-slave relationship. According to the role played in different periods, various theories played a role in each period, only in different fields; Since Emperor Wu of the Han Dynasty "ousted a hundred schools of thought and respected Confucianism alone", Confucianism and Taoism have occupied the mainstream position in the field of ideological rule, but other theories have also played an important role in different fields, such as Taoism in the political field, Legalism, Taoism in the military field, military strategist, Taoism and doctors in the medical field, as well as Taoists, famous artists, Mohists, farmers, Buddhists, Protestants, Muslims and so on. Therefore, there is no division between the schools of Chinese studies, and no school is the main body. [5] It is particularly regrettable that although Confucian masters Confucius, Mencius and Gou Zi strongly advocated benevolence and righteousness, Taoist masters Laozi and Zhuangzi opposed benevolence and righteousness, when Confucianism monopolized the literary world, literature, art, philosophy, history and aesthetics were always dying and lifeless; Once the heretical Taoist doctrine arose, the whole literary world immediately became active, and literature, art, philosophy, history and aesthetics flourished immediately. This wonderful relationship between Confucianism and Taoism is really thought-provoking.
