Sun (646 ~ 69 1) was a calligrapher and calligrapher theorist in the Tang Dynasty in China. Honesty is what you say. Wu Jun was born in Fuyang (now Fuyang, Zhejiang) and Liu Chen (now Kaifeng, Henan). You Zhouwei once joined the army and led government clerks to join the army. Ambitious, liberal arts and ancient. He is good at regular script and running script, especially cursive script. He is a student of Wang Xizhi and Wang Xianzhi, and his brushwork is very strong, which is very suitable for these two kings. He wrote the score of two books, which has been lost. The Preface to the Book Spectrum is divided into six parts: tracing the source, distinguishing the style of the book, evaluating the title, describing the brushwork, admonishing the scholar and hurting the confidant. It is profound and concise, and occupies an important position in the history of ancient calligraphy theory. Many of these arguments, such as the three stages of learning books and the five combinations in creation, are still meaningful today. There is an ink book score handed down from generation to generation.

Sun (646 ~ 69 1 year) was a famous man in the imperial court, and he was very devout. Where is he from? The academic community has never reached a conclusion. Calligrapher and calligrapher in Tang Dynasty. Work, thread and grass are two kings. Fei Xiaotong thinks that Tang Cao is the second French king, which is second to none. However, some critics, such as Dou Wu, ridiculed his book as the same word. Some people say that he is from Yang Gang (now Fuyang, Zhejiang), while others say that he is from Chenliu (now Kaifeng, Henan). He called himself "Wu Guoting" in the Book Score, and he should be from Suzhou. He was born in poverty. In the year of learning Taoism, he paid attention to calligraphy and studied it. He devoted himself to research for 20 years, and finally taught himself. At the age of forty, he became a small official who "led a government clerk to join the army." Because of his noble behavior, he was criticized for losing his official position. After resigning from his post and returning to China, he devoted himself to studying calligraphy and writing book reviews. Unfortunately, he didn't finish the manuscript. Sun died suddenly in a guest house in Luoyang factory because of poverty caused by illness. In the early Tang Dynasty, great poets wrote the Epitaph of Taishigong and the Essays of Weishigong for him, saying that "(Zhong You) died, but it was not passed down. Your legacy is a legacy, which makes him look like a fairy". Comparing Sun with Zhong You, a great calligrapher in the Three Kingdoms period, we can see that he was highly valued in the early Tang Dynasty.

Sun's "good old, literary talent flying, named after calligraphy and painting." He is good at writing letters, lines and cursive scripts, especially cursive scripts. There are three kinds of Sun's handed down books, namely, prose and Jing Fu Dian Fu, all of which are cursive ink, of which the most successful and influential.

Soon after the publication of Sun's Book Spectrum Ink, some people criticized it. For example, according to all the strategists in the Tang Dynasty, Sun Shi cursive script has the style of "Yan Lu (an ordinary person) with thousands of words". This statement was refuted by later experts. Wang Shen in Song Dynasty said, "Li Xi (Sun) is the second king who is good at cursive script. Guo Zhongwei's Qian Wen is vigorous and powerful. Although it is not very elegant, it is still unrestrained compared with Yong's writing. However, Ji Du's book, which refers to the court, is a thousand papers with the same word. Gu Yu has always been deeply suspicious of this language. Since he regained this book, he has studied it for a long time. According to his success, he should not reduce the number of the Wangs. As far as it is concerned, it is still sparse and not known to everyone. " Although Mi Fei in Song Dynasty was harsh on previous calligraphers, he was convinced of Sun's cursive script. He said in "Famous sayings of Haiyue": "Sun Caoshu's Book Score". Very right-wing military law. Write a word, near and straight, this is the law of the court. The world is known as the book of the right army, which was written by Sun. Every Tang Cao has two kings, and they are second to none. " In the Ming Dynasty, Jiao said, "In the past, people commented on Sun Shu, saying that a thousand words are the same, like the wind suppressing grass, but the meaning is light. I said that although Pu Shu was proficient in calligraphy, it was self-evident. The original works that can be read, especially the meaning of Jin people using pens. Liberation without seeking dharma is not bound by law, and it is almost impossible to do this unless you enter samadhi. " Wang Shizhen also said: "For a while, the title of the Book of Filial Piety was unique and derogatory, for example, everything is grass, come to a bad end. Book spectrum is rich and mellow, in the hall of Yin Shan (Wang Xizhi). After standing upright, there is a longing for Youlong. Play it carefully, the so-called word is the same, the beauty is slightly flawed, and you can't hide it. " These analyses and assessments are more comprehensive and to the point than the plan.

In addition to the book spectrum, Sun Qian and Fu of Jingfu Hall are also outstanding calligraphers. Feng said in "Quick Collection": "The Thousand Articles is an original, with regular entry and exit, and its posture is like an unstoppable thing, which seems to have been changed by the right army (Wang Xizhi) and Daling (Wang Xianzhi)." The original work has been lost, and there are two kinds of engravings of legal posts, Yu and Xuan, among which Xuan was written by Song Dynasty and entrusted by Sun Shu. In engraving, the brushwork is skillful, and it is quite imposing. Generally speaking, Sun's book spectrum and Qian's calligraphy were born out of "two kings", from which we can clearly see the method of "two kings". However, the handed down "Fu to Jingfutang" is a kind of weather, and its appearance is far from it, so people have always suspected that it was not written by Sun. This sticker uses a thin and hard nib, which has the meaning of Cao Zhang and has a unique charm. The original ink is now in the Palace Museum.
