In chapter one, it compared letters with pictures and showed the importance of observation. In chapter two, it introduced the structure of human eyes and the course of vision. Chapter three introduced the basic key element of vision and the main theories of studying in vision aesthesia. In chapter four, it analyzed the principle of understanding the meaning of a figure according to the theory before, and analyzed the law of aesthetic. Then it explained how people feel the three-dimensional form and the movement, which have offered the theoretical foundation for creating more vivid image. It expounded the purpose and meaning of judging a visual figure in the fifth chapter, and introduced three general standards. It showed a method of judging the figure from different points of view in an example. Summarize to the full text finally, it point out the correct observation of vision image is one of the main ways for people's study, proposed the weak point of this text.
