For those who study traditional Chinese culture, the scholars of the Tsinghua Institute of Traditional Chinese Culture are internationally renowned both for their academic vision and their extensive publications. The Institute has maintained “kept the disciplines of Chinese Culture, Sinology, and Oriental Studies closely aligned, and has led global academic research in this field.” Indeed, the Institute has remained at the head of Chinese cultural studies over the last hundred years, achieving remarkable results. Initially, Chen Yinque introduced three new methods for the study of traditional Chinese culture, then put into practice by Wang Guowei; these not only became the guiding principles of the “Tsinghua School” but also the fundamental methods of study for all scholars in Modern China. Chen’s principles can be summarized as follows: “use archeological objects and surviving documents to mutually confirm each other”, “allow local materials and foreign ideas together to support the other’s veracity;” and “have foreign and native original writings support each other’s conclusions”. And, to achieve these goals, the scholars learned many languages, mastered different disciplines, merged Chinese and Western learning, and were dedicated to "free thought and independent spirit". Using their vast learning in the application of the three guiding principles, the Tsinghua scholars produced ground-breaking studies across the humanities and social sciences.
