For example, there are better calligraphers than Wang Xizhi, such as Zhang Xu and Huai Su. Both of them are "drunkards' sake", and Wang Xizhi is not as good as them, but Wang Xizhi is still a teacher of their predecessors.
For example, Yan Zhenqing, Liu Gongquan and Ou Yangxun are all better than Wang Xizhi.
Wang Xizhi is a "book saint". He was given this title because of his great role in the evolution of calligraphy, and Wang Xizhi's running script is hard to compare with others.
As soon as he changed his calligraphy style in Wei and Jin Dynasties, his brushwork became smooth and smooth, connecting the past with the future. It can be said that without Wang Xizhi's efforts, there would be no later development of Weeds by Zhang Xu and Huai Su in the Tang Dynasty. This is a historical process of inheritance and continuous improvement.
