The Collection of Critical Biographies of Chinese Thinkers, under the general editorship of the late honorary president of Nanjing University, Professor Kuang Yarning, is the largest-scale project of research materials on Chinese thinkers undertaken since the beginning of the twentieth century. Standing on the shoulders of this great man and other 200 well-known Chinese professors, this collection of concise Chinese-English version is not only based on a profound academic foundation, but also exhibits a brand new feature which is the virtue of explaining the profound in a simple way, hence leading readers to mastery of the contents; it also incorporates a refined principle of selection, a simple mode of evaluation and commentary, and a moving narration of the stories and their wisdom.
