He lived in Mei Liu's house in Jinling for eight years and copied all the rare gold and stone books in his collection since the Qin and Han Dynasties. Suigong's four-body calligraphy is especially good at seal script, with Qin Li Si and Tang Li Yangbing as the ancestors, with a little reference to the official meaning, and it is called a divine product. He was a man of honest nature, traveled all over famous mountains and rivers, and supported himself by engraving books. There is "The Seal Carvings of Wanbai Mountain People Occasionally Exist".

A native of Yizheng, Jiangsu (now Yangzhou). Seal engraver and calligrapher in Qing Dynasty. Bao Shichen's disciple. He is good at calligraphy and painting, especially seal cutting. When he was young, he imitated the seals of the Qin and Han dynasties, and later directly imitated Deng Shiru's style to obtain its essence. He also integrated his own knowledge to develop and perfect the "Deng School" seal cutting art, which played a decisive role in the history of seal cutting schools of the Ming and Qing Dynasties. Wu Changshuo commented: "Rang Weng has always kept his mind on the seals of the Qin and Han Dynasties, and he has studied the seals of the Qin and Han Dynasties very deeply. Therefore, the sword technique is round and round, without any graceful air, with a vigorous atmosphere and quality without stagnation. I once said to the person: After learning Bai Buruo takes the path of Rang Weng."
