Pollock's works have no theme. The painter emphasizes the meaning of painting.

The fundamental significance of Pollock's painting lies in getting rid of all bondage, pursuing extreme freedom and openness, and promoting the development of human's bold creative consciousness. Pollock's action painting first changed the traditional concept of easel painting-painting is no longer an aesthetic design, but a carrier of human movement dominated by the heart; Painting is no longer a symbolic expression of emotion through images or forms, but a direct record of the painter's emotional diarrhea. Secondly, the space of painting has been changed, and action painting has no foreground and background. The traditional composition relationship has disappeared, and all spatial relationships have disappeared. This is a painting with the participation of artists. And the picture has no theme, no center, no primary and secondary, endless. Painting is just one piece of this boundless whole, and this kind of painting can be divided at will.
