Chinese painting embodies the traditional philosophy and aesthetics of the Chinese nation in terms of observation and understanding, image shaping and expression techniques. In observing and understanding objective things, we adopt the method of seeing the big from the small and seeing the big from the small, and observe and understand objective things in activities, and even directly participate in things, rather than appearing locally or being limited to a fixed point.
It permeates people's social consciousness, thus making painting have the cognitive function of "learning to paint after a thousand years of solitude" and the educational function of "warning the world with evil and showing the future with good".
Even the purely natural objective images such as landscapes, flowers and birds are consciously related to people's social consciousness and aesthetic feelings in observation, understanding and performance. The combination of interests, lyricism with scenery, and ambition with things embody China's concept of "the unity of man and nature".
