Part of the gatha of the phantom of the peak in the book, paper, 26.3X109.1cm, collected by the National Palace Museum, Taipei

Rao Jie was the main force among Wumen calligraphers in the late Yuan Dynasty. He has a suave and bold personality, and has the experience of participating in the peasant uprising army. His calligraphy is bold and confident. His cursive calligraphers, Huai Su and Wang Daling, were closely related to Jin Jian from Kanglizishan. Li Rihua commented that his calligraphy was "round, vigorous and smooth, and the gods chase after Daling". His friend Chen Ji said that his cursive calligraphy was "especially graceful and elegant". The representative work "Story Collection of Phantom Live Imagery of Peaks in the Book" uses a clear and vigorous brushwork, sometimes with cursive brushwork, showing the stubbornness in the graceful vigor. The "phantom" structure is deliberately shifted, which is very interesting. His "Nanmu Tie" is casual and unrestrained. It is a short letter, written about a trivial matter. It is full of heroic spirit, the lines are smooth, and it turns with the situation and flows away like a pill. The rhythm of this work is very strong. The shape of the character "ear" in thick ink and dry brush occupies several character positions, while the character "dang" rushes left and right. It is strange and strange, and has a charming charm. The last few words were left with flying smoke, and the "words" were no longer legible. The intervention of Zhang Cao's brushwork also adds line shapes
The change and power are a very rare masterpiece.
