Qigong is good at ancient prose, and has long-term calligraphy and painting practice and contact with Gu Shuhua, so he has deep attainments in identifying the authenticity of Gu Shuhua. He repeatedly compared the unearthed Gu Mo with the manuscripts and engravings handed down from generation to generation, and demonstrated it from many angles. For example, he concluded that the book handed down by Wang Xizhi was untrue because of the fallacy of Cao E's injustice. Inspired by the related books in the Song Dynasty, it is inferred that Zhushantang couplets handed down by Yan Zhenqing are copies used as yellow silk barriers by Song people. It is also verified that the ink in Sun's Book Score is the original, while the ink in Huai Su's Self-narration Post is the original. Qi Gong's works include Ancient Font, Poetic Law, Qi Gong Cong Manuscript and Hundred Poems in Books. Qi Gong was diligent in painting in his early years, good at landscapes and elegant style, and inherited the tradition of literati painting in Ming and Qing Dynasties.
