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. Therefore, Yue Ji always says: "There was a bell in the Han and Wei Dynasties, and Zhang Jue, and there were two kings at the end of Jin Dynasty." These four are called the "four saints" of ancient calligraphers.
