Wu Ju is a good calligrapher as well as a calligrapher of poetry. Especially in calligraphy, Xiaozong often calls for poetry to write lyrics. "Jiangning Fu Zhi" says: "You should stay in Jiankang, near the east tower, and set up a couch at the end of Wei Dynasty. You like Gu Mei very much, and you are posted by Zhong (Yi) and Wang (Xizhi) every day. " Good cursive script, Chinese characters are extremely skilled. Gu Bei's "the best in the world" ink in Jingkou (now Zhenjiang, Jiangsu) was written by Wu Ju. Today, the six Chinese characters still exist, and excellent books add luster to the famous mountains. The obvious feature of his calligraphy is that it looks like Mi Fei, and there is a saying that "you can't peek outside the Minang Palace".
Wu Ju devoted his life to secret books. However, Mi Fei is wild and grotesque, while martial arts is gentle. According to the book Song Shiyi, "Chen Fuliang is a disciple of imperial academy, who cherishes fame and fears righteousness, and is neither arrogant nor impetuous." It can be seen that he has great moral cultivation, so although Wu's research on Mi Shu can reach the point of confusion, Wu's book is more elegant and handsome because of the differences in their personalities. Dong Qichang commented on Wu Juyun: "Books are as handsome as rice yuanzhang." Wu Ju's brushwork is more restrained than Mishu's, which means "handsome".
