The eight calligraphy characters on the website of Nanjing Library are: cherish the yin and think, realize wisdom and be virtuous. Hope to adopt! ! ! ! ! ! !

As the name implies, "cherishing yin and thinking" means cherishing time and advocating thinking. "cherishing yin" emphasizes "learning" and "thinking" emphasizes "thinking". For readers and Nantu people, "paying equal attention to learning and thinking" should be their own accomplishment and cultivation; "Enlightening wisdom and understanding" means enlightening wisdom and trying to guide everyone's morality to a perfect ideal state.
