What are the calligraphy works handed down by Xu Wei and what are their characteristics?

Most of Xu Wei's calligraphy works handed down from generation to generation are cursive, including Poem Axes of Spring Leeks Chopping Night Rain, Ten Poems of Fu Nu Pavilion, Sword Axes Should Be Made When Cursing, Seven-character quatrains, Where is the Cloud Axis of Seven-character quatrains, Songs of Spring, Poems of Seven-character Spring Garden Drizzle, and Seven-character Courtesy. Stroke thickness, dry and wet strokes, and no gap between words and lines. When you look at them, you can see that they roll like clouds, and like a storm, they are luxuriously swept and suffocating. There are no rules and regulations, only Xu Wei's rebellious, arrogant and arrogant venting. Xu Wei's superb grasp of pen and ink, as well as the unevenness between the lines, triggered people's emotional agitation and ideological agitation, and conquered countless artists in later generations.
