What's the style of Wu Guanzhong's paintings?

Wu Guanzhong's painting style is a typical decorative expressionism. His paintings are very smooth and beautiful, and a lot of points, lines and surfaces are used in composition. From the perspective of design aesthetics, many works are perfect, but I still don't like Wu Guanzhong's works very much. His works are too formal, so they lack a little spiritual connotation. Of course, there are many forms of painting, and there is no difference between high and low. Everyone has his own favorite style, so try to draw his own works to the extreme.
