Zhang Zhi's story: Zhang Huan, a general in the Eastern Han Dynasty, had two sons. Zhang Chang, the youngest son, was clever and eloquent since he was a child, and was often praised by his elders. Zhang Zhi, the eldest son, is not as active as Zhang Chang. He is a bit clumsy, but he likes writing very much.
When Zhang Zhi was very young, she would write quietly and intently. After writing, she ran to the pond to wash the ink and stone. Later, I thought it was too much trouble to run around, so I simply set up a square brick platform by the pond and wrote on it like no one was watching.
Sometimes his friends ask him to play, and he doesn't care. My brother laughed at him for being a little stupid, but he was still infatuated and became more and more fascinated with calligraphy. Whether it is cold or hot, he always works hard and perseveres.
He wrote too much and found that paper was scarce, so he simply took the white cloth woven by his mother to write, dyed it, and then continued to write. One day, after practicing calligraphy, he washed his pen and inkstone in the pond. After washing for a long time, he didn't clean it either. Then he suddenly discovered that the clear water was dyed black, just like a big Mo Chi.
However, many things have happened and Zhang Zhi has finally achieved something. In the process of constantly learning calligraphy, he formed his own unique writing style: he changed the cursive writing style of variant characters and strokes at that time into a new writing style with continuous strokes, up and down meanings and rich changes. It makes the words and lines interrelated, looking around, or communicating, or breaking the meaning of the pen, such as flowing, giving people the feeling of one go.
His writing style is called "a book". This kind of "a book" is not continuous writing after being dipped in ink, but refers to the continuous meaning of the whole pen, and occasionally the blood is continuous. Zhang Zhi's cursive script is called "Modern Grass" because it is different from "Cao Zhang". Zhang Zhi is famous all over the world because of "One Book". For a time, scholars were like clouds. At that time, people even cherished his pen and ink to the point of "not leaving an inch of paper".
Summary: Later calligraphers praised Zhang Zhi as a "sage of grass". No matter Wang Xizhi, Huai Su, a master of cursive writing, or Sun, a master of cursive writing, they all learned from Zhang Zhi's cursive writing, which shows that "one stroke" has a far-reaching influence on the development of China's calligraphy. Of course, "a book" is not written in one stroke, let alone in one day.
