In Wu Changshuo's calligraphy creation, seal script and cursive script are undoubtedly the mainstay, but Wu Changshuo's research on official script has a long history. When he was young, he studied Han steles, such as Zhang Qianbei, Songshan stone carvings and Zhanggongfang stele. At the same time, he was influenced by Deng,, and others. His brushwork is similar to that of Yang Jianshan. When he was thirty-five, he wrote an official script. The official script written by Wu Changshuo in his later years became longer and took a vertical trend. For example, this painting "Feng Jue says longevity, elegantly sings blowing sheng" is rich and full, and from some lines, there are traces of seal script. It can be said that at this time, Wu Changshuo has already integrated seal script and official script, forming its own unique features.
Wu Changshuo's regular script can be seen everywhere in the Han Dynasty, such as The Stone Inscription of Songshan Mountain, Zhang Qianbei, Song Mountain and Ode to Shimen. After middle age, I read many original and rubbings of stone carvings, and chose Shi Guwen as the main copying object. For decades, after repeated study, I don't want to be satisfied with imitating my disciples and seeking form. I participated in Qin Quan's inscription, the carved stone of Langyatai and the carved stone of Taishan, so my Shi Guwen is concise, vigorous, novel and unique. Books after the age of 60 are particularly refined, mature and refined, and both rigid and flexible. I like to write couplets in the collection of Shigu characters. In his later years, he used seal script as a cursive script, which was vigorous and bold.
