Wang Xizhi's "Dao Tie" is the most prominent among Youjun's cursive scripts, and later generations called it "one-stroke script". Zhang Chou's "Qinghe Painting and Calligraphy Boat" of the Ming Dynasty says: "There are many old pens, so-called one-stroke calligraphy." In the cross, the first five characters are connected in one stroke, the next two characters are connected, the next two characters are connected in hooks, and the last "ye" The characters are drawn vertically at the end of the stroke to control the blank space of the scale. People who forcefully write a single stroke of writing are often suspected of being artificial, but Wang Xizhi's writing is like moving clouds in the sky, like a swimming dragon, which is extremely precious.
