How to understand the meaning of Wang Xizhi's "book sage"

Let's take a look at the predecessors' evaluation of Wang Xizhi: "Biezhuan": "The fine grass, official position, eight points, flying white, chapters, movements and compilation of Xihe essence are unique, ever-changing and have their own magical powers. How can they reach the top? Their intentions are natural and cannot be added. " Yang Xin: "Xi is more expensive than other products, both ancient and modern, and it is also a combination of multiple methods." Emperor Taizong's biography of Wang Xizhi: "Is it only Wang Yi who looks closely at the past and the present and studies the essence of seal script to make it perfect?" Zhang Huaiguan's "Introduction": "Therefore, we can increase and damage the ancient law, cut into the present body ... get ready for the body, but only the right army." Tang Li Simiao's calligraphy: "Yuan Chang differentiation, differentiation." Sun's Book Score: "It is not only the understanding of the past and the present, but also the deep harmony of feelings ... Writing Le Yi is full of melancholy, calligraphy and painting praise is full of strangeness, Huang Tingjing is full of nothingness, and Taishi is full of disputes, which makes Lanting prosperous." The above evaluation mainly involves two aspects: first, learn from the past, learn from others, and prepare the essence; The second is deep love. The former is the internal strength of writing, which is the basis of Wang Xizhi's high achievement. It belongs to the level of "skill" and the latter is the most important reason for Wang Xizhi's status as a "book saint". Calligraphy belongs to the level of "Tao" and is an art. The essence of art is to express the feelings of the subject (person), and the expressive force is its main feature. According to the different contents of the book, the environment and emotions when writing, the artistic conception and style of the book works also present different types, which shows that calligraphy has the lyrical artistic essence. However, not everyone who studies books can reach this level. To reach this level, there are some preconditions: firstly, the author is required to be a person with "feelings", that is, the so-called "temperament middleman", that is, the so-called "harmony between feelings and depth" in Book Score; Secondly, the author is required to learn from hundreds of teachers in writing skills, forget the rules and be familiar with them when writing. In this way, it is possible for a work to change from one painting to another. Within a little, it is extremely frustrated in the vast mountains, and the created work is "chic and erratic, elegant and flying." Of course, the reason why Wang Xi became a "book saint" is also related to the social environment, personal talent, recognition of future generations and the agreement with China people's traditional aesthetic thought in the Eastern Jin Dynasty. Moreover, Wang Xizhi's position was not achieved overnight. There was a dispute of "Zhong, Zhang and Two Kings" in the Southern Dynasties, and Wang Xizhi's position was finally established after the early Tang Dynasty. We analyze how Wang's book conforms to the above aspects from the traces handed down by him.
