Zhang Fei, with the word Yide, was a famous soldier of Shu and Han in the Three Kingdoms period, and was called "enemy of ten thousand people" with Guan Yu. Historically, Zhang Fei was not only a famous soldier of the three armed forces, but also a great calligrapher. According to Zhuo erchang's Fine Interpretation of Painting in Ming Dynasty, Zhang Fei not only likes to draw beautiful women in calligraphy, but also is good at cursive writing. According to legend, many inscriptions were written by Zhang Fei, and the words on his sword were written by himself. Wu Zhen, a painter in Yuan Dynasty, once wrote poems and praised Zhang Fei's calligraphy, saying that Zhong You of Wei and Emperor Wu were probably not as accomplished in calligraphy as Zhang Fei.

From these records and evaluations, we can see that Zhang Fei's calligraphy is brilliant. His works were not only highly respected at that time, but also praised by people in later generations. His cursive style is unique, vigorous and lively. In his works, there are both rough and bold momentum and subtle emotions. This unique artistic style makes Zhang Fei's calligraphy occupy an important position in the history of China's calligraphy.

Generally speaking, Zhang Fei's calligraphy is undoubtedly an artistic treasure, which not only shows his talent and artistic accomplishment, but also provides us with an important way to understand and appreciate ancient works of art.
