Zhong Yao (151-230), whose courtesy name was Yuan Chang, was a native of Changshe, Yingchuan (now Changgedong, Henan). When he reached the rank of Taifu, he was known as Taifu Zhong. He was one of the founding ministers of Cao Wei. Together with Zhang Zhi, Wang Xizhi and Wang Xianzhi, he is known as the "Four Sages in the Book", and together with Wang Xizhi, he is known as the "King of Bells". Zhong Yao was in the transition period from official script to regular script. Yang Xin said that he was good at three types of calligraphy, namely inscribed stone script (official script), charter script (regular script) and Xingya script (running script), and made the greatest contribution to regular script. "Xuanhe Shupu" says: "Kaifa is now the official script. Zhong Yao's "He Ke Jie Biao" has all the legal standards and is the ancestor of the official script." This shows that the new regular script that appeared at that time, it was in his hands that he wrote the rules and basically finalized it. However, due to the relationship of the times, his regular script still has a strong official script style. Yang Xin's article "Cai Gu Lai Can Write Names of People" mentions that Cizhong, the king of Shanggu, created an "eight-point regular script". Some people think that Zhong Yao's "He Jie Biao" should be the representative of this "eight-point regular script". Regarding the characteristics of Zhong Yao's calligraphy, Emperor Wu of Liang Dynasty once described it as "like clouds and cranes flying in the sky, and a group of Honghong playing in the sea. The lines are dense, but it is actually sad." Zhang Huaiguan said: "It is both strong and soft, and there are many interesting things in pointillism. It can be said to be profound and profound, yet more than quaint and elegant." Dense and deep, with a kind of quaint taste, are the main characteristics of Zhong Yao's calligraphy. His works that have been handed down include "He Jie Biao" (i.e. "He Jie Biao", "Rong Lu Biao"), "Jian Ji Zhi Biao", "Li Ming Biao", "Huan Shi Biao", and Wang Xizhilin's "Shang Shu Declaration Table", "Bing She Tie", etc. Among them, "He Jie Biao" was written in the 24th year of Jian'an by Emperor Xian of the Han Dynasty (219). It was a good report written by Zhong Yao when he learned that Shu general Guan Yu had been captured and killed. Now only the engraved version has been handed down. It is the work that best represents Zhongshu's style. There is also the "Recommendation of Ji Zhi", which is a memorial to recommend Ji Zhi, an old minister who had resigned long ago, to come back to serve as an official. The original ink volume was once in the imperial palace of the Qing Dynasty. It was robbed by British soldiers when the Old Summer Palace was destroyed, and was later kept in a private collection. The original copy has been destroyed, and only one photo survives. In the Ming Dynasty, this post was engraved into "Zhen Shang Zhai Tie" and in the Qing Dynasty, it was engraved into "Sanxi Tang Tie", ranking first among all posts. This post has always been highly regarded. For example, Wang Shizhen of the Ming Dynasty said that although this ink mark exists in the world, "Chunhua Pavilion is no longer known to exist".
