Perceptual thinking and rational thinking are two important forms of thinking which are indispensable in people's life. By definition, perceptual thinking can be summarized as the behavior of thinking and judging objective objects based on personal intuition and existing experience, while rational thinking can be summarized as the induction and summary of objective things through the scientific and rigorous knowledge system and methods currently mastered. The relationship between perceptual thinking and rational thinking coexists with each other, which is indispensable and plays a vital role in the creation process of painting art. From beginners to masters who have already stepped into the palace of art, these two forms of thinking run through their paintings, reflecting the interweaving of sensibility and rationality in artistic concepts and artistic styles, as well as the influence of the two on the observation and feeling of the objects expressed, the inner understanding, the choice of language and other aspects.
