His calligraphy attainments are highest in cursive script, and his calligraphy is based on "Two Kings", which is also attributed to Yan Zhenqing, Mi Fei and Yang Ningshi. Zhao Mengfu's calligraphy style also affects his creation more or less. The cursive script is rooted in Yan Zhenqing's "Contention for Seats" and "Sacrifice for Nephew", with Huai Su's roundness and Mi Fei's ups and downs. Use a pen accurately and always keep a positive face. There are few stagnant and sluggish pens in the works; Ink is also very particular, dry and wet, wonderful; Simple and natural style, simple and peaceful, or related to his temperament, easy to understand Zen. There is grass between the lines in many works. The picture on the left shows Yan Zhenqing's frankness, Mifei's posture and Yang Ningshi's carefree Shu Lang, which looks like Zhao Mengfu's charm, agility and self-sufficiency. Dong Qichang is also quite conceited about his regular script, especially in lower case.
Dong Qichang is knowledgeable and proficient in Zen. He is a master of calligraphy and painting and has a certain position in the history of China fine arts. His "Essays on Painting Zen Rooms" is an extremely important work to study the art history of China.
