Wang Shu is an excellent scholar and devoted to calligraphy. Li Si and Li, who used regular script and seal script, were the first calligraphers who were famous for seal script in Qing Dynasty. "History of the Qing Dynasty" says: "Critics say that his books are above Mi Fei, Huang and Gu." His seal script basically retains the characteristics of "Li Er" seal script method, with strict and neat words and even and symmetrical distribution. On the basis of roundness and roundness, he comprehensively uses flat and oblique straight lines to produce square and triangular spaces to echo, so his seal script is particularly clear and refreshing. Works handed down from ancient times include Ode to Wine Virtue, Poem Axis of Thousand Guas, Han Jingming and so on.
In addition, Wang Shu has made great achievements in calligraphy theory. On the one hand, he suppressed posts and raised monuments; On the other hand, he denounced the worship of Dong in the early Qing Dynasty as a "bad habit of Dong Shi family"; On the other hand, he advocated that learning calligraphy should start with seal script and official script, which played an important leading role for many calligraphers after Qianlong.
