There is a Confucius portrait in both books, Mencius and Xunzi. From the similarity of the portraits, one could find the influence of the sacred image of Confucius on Mencius's and Xunzi's philosophic thought, as well as the existence of Confucianism spirit. From the difference of the portraits, one could also see the different interpretations of Mencius's and Xunzi's philosophies are deeply associated with ”Confucius” images and beliefs. This phenomenon, not only shows the variety of ”Confucius” portraits, but also demonstrates transitions and interpretations made in the process of developing philosophy.
