Wang Xizhi was called the "Sage of Calligraphy" after the early Tang Dynasty. Li Shimin, Emperor Taizong of the Tang Dynasty, highly praised Wang Xizhi and belittled Wang Xianzhi. He not only extensively collected Wang Xizhi's calligraphy, but also personally wrote a praise for "Book of Jin: Biography of Wang Xizhi". Commenting on Wang Xianzhi, he derogated him for his "disease of calligraphy" and commented on other calligraphers such as Wang Meng and Wang Xianzhi. Xu Yan and his contemporaries all said that "the reputation exceeds the reality". Through comparison, Emperor Taizong of the Tang Dynasty believed that Wang Youjun was "perfect" and "he is the only one who is chasing after him with all his heart, and the rest are just trivial." From then on, Wang Xizhi's supreme position in the history of calligraphy was established and consolidated.
People who studied calligraphy in the Song, Yuan, Ming and Qing dynasties all respected the "two kings" of the Jin sect. Ouyang Xun, Yu Shinan, Chu Suiliang, Xue Ji, Yan Zhenqing, Liu Gongquan in the Tang Dynasty, Yang Ningshi in the Five Dynasties, Su Shi, Huang Tingjian, Mi Fu, Cai Xiang in the Song Dynasty, Zhao Mengfu in the Yuan Dynasty, Wen Zhengming and Dong Qichang in the Ming Dynasty, all calligraphy masters in the past dynasties converted to Wang Xizhi .
Although in the Qing Dynasty, steles replaced calligraphy and the study of stele broke the study of calligraphy, Wang Xizhi's status as the "Sage of Calligraphy" remained unshaken. Although the "Sage of Calligraphy" and the "Emperor of Mo" are suspected of "sanctification", the calligraphy giants of the past dynasties are all convinced and highly respected through comparison and speculation.
