Sun Guoting's "what an ancient scholar, a literary work, named after the calligraphy room". He is good at writing letters, lines and cursive scripts, especially cursive scripts. There are three kinds of Sun Guoting's handed down books: Shupu, Qianzi Wen and Jingfu Dian Fu, all of which are cursive ink, among which Shupu is the most successful and influential.
Sun Guoting's Book Score was criticized shortly after it came out. For example, Dou Ji in the Tang Dynasty said that Sun Shi's cursive script has the style of "Lu Yan (ordinary people), and there are thousands of papers with the same word". This statement was refuted by later experts. Wang Shen in the Song Dynasty said, "Qian Li (Sun Guoting) is the second king who specializes in cursive writing. Guo Zhongwei's "Qian Wen" is vigorous in brushwork. Although it is not very elegant, it is bold and unrestrained compared with what Yong Shi (Zhiyong) wrote. However, Dou Ji's book, which refers to the court, is a thousand papers, with the same word. Yu Gu has been deeply suspicious of this language, and since he regained this book, he has been studying it for a long time, depending on his success, he should not reduce the Wangs and his son. As far as it is concerned, it is still made in sparseness, which is not known to all. " Although Mi Fei in Song Dynasty was harsh on the previous calligraphers, he was completely convinced of Sun Guoting's cursive script. He said in "Famous sayings of Haiyue": "Sun Guoting cursive" Book Score ". Very right-wing military law. If you write a word, you will be near and straight, which is a court law. All the world is called the book of the right army, and all these words are written by Sun. Every Tang grass has two kings, and it is second to none. " Jiao said in the Ming Dynasty: "In the past, when people commented on Sun Shu, they said that a thousand words were the same, like the wind suppressing grass, and the meaning was light. I said that although Shupu is well-versed in calligraphy, it is self-evident. You can see the original works of Qian Wen, especially the meaning of Jin people using a pen. It is not bound by the law to get rid of it without seeking the law, and it is almost impossible to do this unless you enter samadhi. " Wang Shizhen also said, "For a moment, the title of the book of piety and propriety was unique and derogatory, such as saying that everything is grass and death. The Book Score is rich and mellow, and it is in the hall of Shanyin (Wang Xizhi). After the vertical release, there is a thirst for Youlong. If you play it carefully, the so-called word is the same, and the beauty is slightly flawed, so it cannot be concealed. " These analyses and evaluations are much more comprehensive and pertinent than dou Ji.
