Zhang Zhi, born in an unknown year, died in the third year of Emperor Xianping of Han Dynasty (about AD 192). He was born in Yolanda, Dunhuang, 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, were called' book saints' at that time, but they were strong and muscular, and they were the first of all saints. Of course." Zhang Zhi was born in a famous family, but he was "a young man with lofty ideals and was diligent in learning ancient times". He didn't care about fame, refused to be called up by the court many times, and devoted himself to studying. His fighting spirit of "learning from one pond, making the pond full of ink" has become a well-known anecdote in China calligraphy circle. Wang Xizhi once said respectfully that Zhang Zhi "learned from a pool, and the water in the pool was full of ink, so was I." "There are 20 poems about Dunhuang monuments sung by predecessors, including Ode to Mo Chi: the ancients used seal cutting elements to make Zhang Zhi wonderful. The sage of grass is immortal and famous for a while. Shu Jian watches birds, studies ink and dyes fish. I am eager to be by the pool, and I am happy to talk about poetry.
In this way, Zhang Zhi was indifferent to Li Rong and worked hard to reach the first peak of calligraphy art in China.
