What are Zhong You's artistic features in calligraphy?

Zhong You (15 1 ~ 230) was born in Yingchuan Changshe (now Changgedong, Henan). Master Guan Ju, also known as Master Zhong, was one of the founding ministers of Cao Wei. He, Zhang Zhi, Wang Xizhi and Wang Xianzhi are also called "the four saints in the book", and Wang Xizhi is also called "Zhong Wang". Zhong You is in the transition period from official script to regular script. Yang Xin said that he is good at three-body calligraphy, that is, Shi Ming's calligraphy (official script), articles of association (regular script) and running script (running script), especially regular script. Xuanhe Pu Shu said, "Dafa is the official book of today. Zhong You's He Jack Table is the originator of official books. It shows that a new regular script appeared at that time, and it was only in his hands that the statutes were written and basically finalized. However, due to the times, his regular script still has a strong sense of official script. Yang Xin's article "Selected Names of Ancient Books" mentioned that Wang Cizhong of Shanggu created an "eight-point method". Some people think that Zhong You's "He Jie Biao" should be the representative of this "eight-point method". Regarding the characteristics of Zhong You's calligraphy, Liang Wudi once described it as "a cloud crane swimming in the sky and playing in the sea, with dense lines, which is really sad". Zhang Huaiguan said: "There are many differences between stippling and painting. It can be described as profound and boundless, and quaint. "Zhong You's calligraphy is characterized by profundity and elegance. His works are He Jie Biao (He Biao and Rong), Ji Zhu Biao, Li Ming Biao and Huan Shi Biao, as well as Wang Xizhi's Xuan Biao of Shangshu and Bing Xie Tie. Among them, He Jie Biao was written in the 24th year of Jian 'an of Emperor Xian of Han Dynasty (2 19), which was the good news that Zhong You learned that Guan Yu, the general of Shu, was captured and killed. Now only block printing has been handed down, which can best represent the style of Zhong Shu. In addition, "Ji Zhi Biao" is a table recommending Ji Zhi, an old minister who resigned long ago, to come out as an official again. The original ink has entered the Qing government, and the Yuanmingyuan was taken away by British soldiers when it was destroyed, and then it was privately collected. Now the original trace has been destroyed, leaving only one photo. This post is engraved in Shang Zhen Zhai Tie in Ming Dynasty and Sanxitang Tie in Qing Dynasty, ranking first among all posts. This post has been receiving rave reviews. For example, Wang Mingshizhen said that this ink exists in the world, but "Chunhua Pavilion is unknown".
