Zhang Yi, a calligrapher at the end of the Han Dynasty and the beginning of the Three Kingdoms, was called

Not Zhang Yi, but Zhang Zhi. Zhang Zhi, born in an unknown year, died in the third year of Chu Ping of Emperor Xian of Han Dynasty (about AD 192), and was named Boying. Han nationality, from Jiuquan, Dunhuang (now Jiuquan, Gansu). Calligrapher of the Eastern Han Dynasty. Son of Zhang Huan, a senior farmer in Sanming, Liangzhou. Born into an official family. Zhang Zhi is good at cursive Cao Zhang. He changed the ancient cursive calligraphy of distinguishing characters and dividing strokes into a new writing style, which was original and influential at that time and was known as the sage of grass. Now there is no ink handed down from generation to generation, and only his August post is included in the Chunhua Pavilion post in the Northern Song Dynasty. Zhang Zhi, Zhong You, Wang Xizhi and Wang Xianzhi are also called the four saints in the book. Zhang Zhi, whose birth year is unknown, died in the third year of Chu Ping of Emperor Xian of Han Dynasty (about AD 192). He was born in Yolanda Town, Guazhou County, Jiuquan City, Dunhuang (now around Sidaogou Old Town, Guazhou County, Jiuquan City, Gansu Province), and his name is Boying. Study hard and be good at ancient times, but be weak at ancient times. When the court refused to sign the Tao, people called themselves "Zhang Youdao". If he is good at Cao Zhang, he will get rid of the old habits, preserve Cao Zhang's stippling and become a "modern grass". In the Broken Book, both Cao Shu and Cao Shu are listed as gods, saying, "You Cao Shu was born in Du and Cui Ai. Dragon and leopard change and shine on you. It is also made in this grass. It is not a pity that the weather is different and the rate is over-opened. If Qingjian has a long origin, then infinite flow will return to Cliff Valley and let it be natural "; Known as "learning the method of Cui (Yuan) and Du (Cao), it is strange to change it to this grass." The style of Chinese characters is formed by strokes, occasionally disconnected, but the blood vessels are continuous, even the veins are connected. Dan Wei, a calligrapher of the Three Kingdoms, called him "the sage of grass". Jin Wang's book only praised Zhong (Yao) and Zhang (Zhi) for Han and Wei calligraphy, but thought the rest were not satisfactory. Zhang Xu, Dan Wei, Suo Jing, Wang Xizhi and his son, Zhang Xu and Huai Su all came from Boying. Yang: "Zhang Zhi, Zhong You and others were called' book saints' at that time, but they were strong and muscular, and they were the first of all saints, so it was natural. "
