The pursuit of knowledge in China’s “all-round learning” is not limited to specialized fields, but dedicated to understanding the general principles and knowledge, with the pursuit of the path to wholeness as its highest purpose. Deeply influenced by the idea, Zhang Xuecheng shows a holistic approach to knowledge in his theory of “Six Classics are all history”, which reflects a historical inheritance of this spiritual tradition. Zhang Xuecheng’s theory of “Six Classics are all history” and the spirit of “all-round learning” in China still have historical echoes in modern times. From the modern academic perspective, Zhang Xuecheng’s theory provides a way of learning which is based on the spirit and seeks to achieve overall knowledge. Today, Chinese tradition of “all-round learning” has integrated new knowledge and sprouted new shoots in the new era.
