Wang Xizhi's brush calligraphy is the best. Wang Xizhi's reputation as a calligrapher is not empty. He worked hard and made great achievements. He is a monument in the history of calligraphy in China, imitated by calligraphers of past dynasties and never surpassed. His running script has a profound Confucian cultural background, which is neither inspiring nor vigorous, and its style is far away. His running script "Preface to Lanting Collection" is a masterpiece throughout the ages, and the famous monk and calligrapher Huairen spent decades of painstaking efforts to integrate the "Preface to the Sermon of Huairen Collection of Wang Xizhi", which is also the best example for us to learn brush calligraphy!
