Wu Changshuo's seal cutting started with "Feihongtang Yinpu", then transferred to Zhejiang School, and then learned from Deng Shiru, Wu Rangzhi and Zhao Zhiqian. Wu Changshuo studied Shi Guwen for a long time, and he once said, "To learn seal script is good for the Stone Drum, and he has been engaged in it for decades, and one day will be the realm." His calligraphy has become an important feature of his printing.
Contrary to Huang Shiling, his printing is a kind of pungent, so-called rude and messy printing style. The impression given is a kind of beauty that is thick, boundless and magnificent. In addition to imitating the bold works such as "Shigu" as the keynote, he also adopted many unprecedented methods in using tools and engraving methods. For example, he used an obtuse angle carving knife. He combined Qian Song's cutting technique with Wu Xizai's punching technique. Paying attention to the force of blunt knife has become a special and novel method of using knife. His seal can be seen in beauty and vigorous, and in rudeness, it does not lose its elegance. Wu Changshuo is unique in the history of Chinese Indian studies, with distinctive personality characteristics. As far as the bold and unconstrained way is concerned, the predecessors are incomparable. As far as the maturity of personal style is concerned, it is also rare in the history of Indian studies.
