How to explain the characteristics of Wang Xianzhi's calligraphy?

The ancients commented a lot on the calligraphy presented, such as Yang: "The kindness presented (referring to the real book) and the calligraphy presented (referring to the cursive script) are not as good as the father's book, but they are too charming." Li Houzhu said: "Amethyst got the body of the right army, but she was surprised and anxious, with no implicit attitude." (See Ma Zonghuo's book Tree Algae) Zhang Huaicui said: "Amethyst has a unique charm and a particularly beautiful figure. His process is simple, and his goal is surprise. From here on, it is both dangerous and profound. "Xiang Muyun (Book Review):" When books are respected by children, the door to novelty opens. "The so-called" charming ","surprised ","surprised "and" curious "have different words, but their meanings are quite similar. Yang Xin said that his calligraphy is "inferior to his father", which is different from Li Houzhu's "attitude without implication", revealing the fundamental points of the two kings' calligraphy, which are implicit, deep, peaceful, flexible and beautiful in connotation. The book presented is free and easy, opening a wonderful place and beautiful. Compared with Zhong You's books, our books are better than Yi's, and strict books are better than Wang's. Therefore, Xiang Mu in the Ming Dynasty said that "books are respectful to children, and the door to novelty is open". The Book of Dedication pursues more formal beauty than semantic beauty, which is why it is called "the world knows". This is fully reflected in his real books and cursive scripts. Zhang Huaicui said: "The son is God and the father is peace. "If boxing is used as a metaphor, the book of Xi is like a family boxing, combining rigidity with softness, and the book given is like a family boxing, combining rigidity with softness, each making its pole. Wang Xianzhi's style of "seeking novelty" has a far-reaching influence on later generations and has become the ancestor of many heroic and novel calligraphers of Tang Zhangxu, Huai Su and Song and Ming Romantic School. " "The Monument to the Valley" says: "I tried to compare the cursive script of the right army with that of the father and son. The right army is like the left, and the big order is like Zhuang Zhou. Since the Jin dynasty, it is rare to be as clean as two kings. "Zuo Si's language is simple and Zhuangzi's style is bold. Compared with the two kings, it is quite real." "Dust-free" is the common feature of the calligraphy of the two kings. For thousands of years, calligraphy styles have been ever-changing, and masters have emerged in large numbers, but not many people can "escape" at this point.
