In calligraphy, Mo Youzhi was deeply influenced by the thought of stele studies and was good at both seal script and official script. Ma Zonghuo's "Shu Lin Zao Jian" says: "Both the seal scripts and official scripts of Lü Zangting are ancient and clumsy, with the spirit of gold and stone. They are not judged by their appearance. Although the instrument is a little narrow, the beauty of the seal script and official script is solid and deep." It is thick, decisive, and the characters are clumsy and simple. Especially the seal script was famous for its elegance at that time. The seal script is from "Shaoshi Stele". The method is very high and the style of the strong pen is unique. There are works such as "Seal Script Screen" and "Xunzi Yu Screen" handed down from generation to generation.
