Zhao Mengfu used the brushstrokes of calligraphy to describe different objects, which turned realism into freehand brushwork, but it did not degenerate into graffiti like the "ink play" in Song Dynasty, which solved the formal problem of "painting and calligraphy are of the same origin" and paved the way for the communication of artistic conception with the style of combining expressiveness with painting. In Zhao Mengfu's paintings, the outline of the slope stone is swept sideways with a brush, and the vigorous strokes are full of white, which is a typical "flying white" method in calligraphy. Dead wood is painted from the center, with a dignified picture and the interest of ancient inscriptions; Draw bamboo leaves with eight points. The bamboo leaves are plump and solid, with swaying branches and leaves. The whole picture has both the brushwork of calligraphy and the ink color of painting, and the level of calligraphy is far above that of Su Shi.
