1. The author of the self-narrative post is a cursive calligraphy work by Huai Su, a calligrapher from the Tang Dynasty in my country. The whole text is in wild cursive. It is the ultimate expression of the art of cursive calligraphy and has been praised by future generations as "the best cursive calligraphy in the world". Huaisu is famous for his "Kuaicao" and is called the "Sage of Cao". He became a monk since he was a child. Together with Zhang Xu, he is known as "Dian Zhang Kuangsu".
2. Huaisu (737~799), known as the "Cao Sheng" in history, was an outstanding calligrapher in the Tang Dynasty. His courtesy name is Zangzhen, his monk's name is Huaisu, and his common surname is Qian. He is Han nationality and a native of Lingling, Yongzhou (Lingling, Hunan). He is the nephew of Qian Qi, one of the ten talented men in the Dali calendar.
3. He became a monk since he was a child. During his free time from meditation, he devoted himself to cursive writing. He is as famous as Zhang Xu and is collectively known as "Dian Zhang Kuang Su". It formed a situation where the two peaks of calligraphy in the Tang Dynasty coexisted and was also the best in Chinese cursive writing. Two peaks in history. Huaisu's cursive calligraphy is thin and vigorous, with natural flying movements, like a sudden rain and whirlwind, changing at any time. Calligraphy is straightforward, ever-changing, and full of rules. Li Zhimin, a professor at Peking University and the founder of introducing monuments to cursive scripts, commented: "Huaisu's cursive script has a graceful spirit in its rush and ease, and a pure and honest spirit in its wildness."
4. The calligraphy works handed down from generation to generation include "Autobiography Calligraphy", "Xiaocao Thousand Character Essay" on paper, "Bitter Bamboo Shoots Calligraphy", "Notre Dame Calligraphy" and "On Calligraphy Calligraphy".
5. "Autobiography" is Huaisu's autobiography of his life in general, and also contains poems written by Yan Zhenqing, Zhang Wei, Dai Shulun and others. The whole text is full of wild grass, with the center of the strokes like a cone scratching a sand table, vertically, horizontally and diagonally, and going in all directions; the whole volume emphasizes the continuous grass flow, turning the brush up and down, sometimes left and now right, ups and downs, some fast, some fast, some light and some. Heavy, full of rules and regulations, with strange changes and turbulent expressions, it is the ultimate expression of the art of cursive calligraphy.
