Zhang Zhi, a "sage of grass" at the end of the Eastern Han Dynasty, Zhong You, a master and regular calligrapher in the Cao and Wei Dynasties, and Wang's father and son's ink at the end of the Eastern Jin Dynasty are called "unique in ancient times". In order to prove the objectivity of his unique point of view, the author quoted a sentence from Wang Xizhi, a calligrapher with a high position and a clear pronunciation: "Looking at all the books, Zhong and Zhang Xin are second to none, and the rest are insufficient." On the other hand, Wang Xizhi absorbed the essence of Zhong and Zhang and pushed the art of calligraphy to a new height. Wang Xianzhi (344 -386), a calligrapher and poet in the Eastern Jin Dynasty, was born in Huiji (now Shaoxing, Zhejiang) and the seventh son of Wang Xizhi. In order to distinguish it from later calligrapher Wang Min, people called it Wang Daling. He and his father are also called "two kings". Wang Xianzhi practiced calligraphy with his father since childhood, and he was very ambitious. Later, he regarded Zhang Zhi as a whole. He is famous for his running script and cursive script, but he also has a deep foundation in regular script and official script, because Tang Taizong didn't appreciate his works very much, and his works were not as many as his father's. The masterpiece "Thirteen Lines of Luo Shen Fu" handed down from ancient times is also called "Thirteen Lines of Jade Edition".
