Wu Dacheng is good at the identification and textual research of ancient Chinese characters, as well as seal cutting, calligraphy and painting. Wu Dacheng's calligraphy is most famous for seal script. His seal script is very distinctive, combining the ancient seal script with the small seal script, and his skill is very deep, that is, he usually uses neat and exquisite seal script for it, with neat rules and unique feelings. He studied seal script with Chen Shuo's father in his early years, and took part in the study of ancient seal script after middle age, which was of great benefit to calligraphy. In Qin dynasty, he studied stone with Xiao Zhuan, and his calligraphy was like Li. Later, inspired by Yang Yisun, he combined Biography with inscriptions on bronze and wrote The Analects of Confucius, The Book of Filial Piety and Letters in this way. His seal script was uneven in size, elegant and simple, which was a creation at that time. He studied epigraphy deeply, which broadened his vision of pre-Qin characters and made his seal script draw a lot of nutrition from it. Wu Dacheng writes seal script and likes to use official script. His official script is horizontal and vertical, and he also carries the Fahan tablet. Learning Zeng Guofan's running script is quite interesting for Huang Tingjian.
