Textology has gradually become an important field and special research area in the overall pattern of Chinese Marxism since the beginning of the 21st century. Scholars have honed new explanations with new understandings concerning the relations between the origins of Marx's thought and the Western cultural tradition, the continuity and essence of Marx's thought through change, the complexity of Marx's theory of capital and the arduousness of the criticisms against it, and the concrete contents of communism. Reflecting on the various attitudes in understanding Marx historically allows an exploration into the basis and method of Marx's 'textology' that pursues in-depth case studies of texts. This helps to rectify long-standing misunderstandings and to realize the contemporary development and lasting value of Marx's thought.
