Four Ancient Poems embodies the style and characteristics of Zhang Xu's cursive script. In the whole layout, the grand situation of Xiong Si is highlighted in the strong ups and downs. This post is very hearty, like' red and white? Driving a thousand miles' is quite aggressive. Its glyph is fickle, and sometimes when the wind blows, it is Ma Benteng; Sometimes it seems to be low and high, and the turning point seems to be urgent, which is full of changes of' I move, my soul flies, I am suddenly enlightened, and I am long', which is a direct manifestation of the artist's open-minded and sincere character.
In the use of pen, this post is round and implicit. With the release of feelings, the pen seems to be rhythmically heavy and light, and the lines are concise and vigorous, or floating and mixed, with a' leak mark' like texture. Dry pen has astringency and tension like' cone sand', and the harmonious combination of stippling and lines constitutes a natural, vivid and magnificent picture. It can be said that "Four Ancient Poems" is not only an impressive classic in the calligraphy art of Crazy Grass, but also a symphony in the romantic artistic style. Huai Su's cursive script is vivid and radiant. In his wild grass works, he often "only looks at the spirit, but doesn't see the five senses", full of paper and smoke, but he can feel the rich smell of pen and ink, giving people a magnificent artistic enjoyment.
