Sinology rose in the early 20th century and flourished in the 1920s. In the 1980s, the craze of "seeking roots" appeared, and in the 1990s, the craze of "Chinese studies" rose again, which is a reflection and a face-up to traditional culture. Today is the repositioning of traditional culture in today's multicultural China and even the world. The spread of western learning to the east gave birth to Chinese studies. The theory of "Chinese studies" came into being in the historical period of western learning spreading to the east and cultural transformation. Strictly speaking, the academic circles have not given us a unified and clear definition of Chinese studies so far. Famous experts have different opinions, but they can't agree. Generally speaking, Deng Shi, the quintessence of Chinese culture, wrote in 1906: "What is a China scholar? A country's learning is also. Life with land is on it, because there is a country, and people with a country have their own knowledge. Learning to be excellent is an official, learning to be excellent is an official, and governing the country is safe. " Lecture on Chinese Studies, Chinese Cooking Magazine. 19) Mr. Deng's concept of Chinese studies is very broad, but he mainly emphasizes the practicality of Chinese studies. The Information Center of the International Friendship Association has the following definitions of Sinology: China Studies, which can be translated as "Guo Xue" and "Sinology" (meaning China Studies or Sinology). In a narrow sense, Sinology refers to China's traditional culture and scholarship with Confucianism as the main body. Nowadays, the traditional Chinese studies generally refer to a unique and complete cultural and academic system based on pre-Qin classics and hundred schools of thought, including Confucian classics in Han Dynasty, metaphysics in Wei and Jin Dynasties, Neo-Confucianism in Song and Ming Dynasties, Han Fu in the same period, parallel prose in Six Dynasties, poems in Tang and Song Dynasties, Yuan Qu and novels in Ming and Qing Dynasties, and historiography of past dynasties. Therefore, in a broad sense, China's ancient and modern culture and scholarship include history, thought, philosophy, geography, politics, economy, calligraphy and painting, music, astrology, medicine, astrology, architecture and so on. They are all involved in Chinese studies. Controversy between Chinese studies and western studies. The original name of Sinology originally meant national universities, such as ancient imperial academy and imperial academy. Simply talking about Chinese studies refers to classics, history, Confucianism and Ji Bu's classical exegetical knowledge. Since the spread of western learning to the east and the cultural diversion and transformation, in order to distinguish it from western learning, people have called all the "six arts, five arts" and "hundred schools" in China "national studies". Western learning flourished in the East, while Eastern learning declined. Around the New Youth Movement since the May 4th Movement, some masters of Chinese studies began to argue with Western learning in order to protect Chinese studies. The Western School thought that it would accept Western learning in its entirety, while China scholars swore to their ancestors. The development of the separation of Chinese traditional culture and western learning. Sinology is unique to China, but in the modern historical period of China, due to the division of Manabu Nakanishi, sinology and western learning began to develop separately in China. In Chinese mainland, Sinology was destroyed by breaking the four traditions. Since the reform and opening up at the end of the Cultural Revolution, China people's ideological, academic and cultural freedom has gradually recovered, and the academic space of China's traditional culture has gradually expanded and prospered. Since the reform and opening up in the 1980s, "Sinology" has revived to this day. Sinology, which rose at the beginning of the twentieth century, flourished in the twenties, and there was a "root-seeking" craze in the eighties. The craze for "Chinese studies" in the 1990s has since revived, which is the reflection and face-up of modern people on traditional culture. Today is the repositioning of traditional culture in today's multicultural China and even the world.
