Professor Yangjingjian’s work History of Chinese Existentialism Literature in the 20th Century views the existentialism literature as a literature ideological trend, which is considered and reviewed in the course of China’s “modernity” as well as in the integral pattern of Chinese literature in the 20th century. In this book, existentialism literature was considered as a structural existence of Chinese literature in the 20th century, and its development history was also combed and examined in details, which greatly expanded and deepened the studies of Chinese existentialism literature in the 20th century and also provided a new perspective to it.
