The regular scripts of the three great calligraphers of the early Tang Dynasty, Ouyang Xun, Yu Shinan, and Chu Suiliang, are all the most suitable copy models for Chinese regular script. The respective brief introductions are as follows:
Ouyang Xun's block script originated from ancient Li, based on Erwang style, and referenced the calligraphy style of the Northern School of the Six Dynasties. It has a unique structure, an original style, and is particularly authoritative. Its influence has penetrated deeply into society, and it has become almost the standard book for academics. The characteristics of regular script are that the pen is strong and sharp, the strokes are square and neat, and the structure is cheerful and healthy. His representative regular script inscriptions include the "Jiucheng Palace Liquan Inscription" and the "Huadu Temple Stele".
Yu Shinan's regular script is elegant and elegant, inheriting the legacy of Zen Master Zhiyong and being a direct descendant of the Wang School. Although it originated from the Wei and Jin Dynasties, its soft exterior and strong interior, as well as its deep and serene charm, swept away the cowardice of the calligraphy style of the Wei and Jin Dynasties. Among his representative works in regular script, "Confucius Temple Monument" should be the most representative.
Chu Suiliang's regular script is famous for its sparseness, thinness, and strength. Although he originated from the Youjun army, he is still charming. Its font structure seems to be very unrestrained, but it can skillfully reconcile the quiet style, creating a situation that has never been reached before. His representative regular script works should be the "Preface to the Holy Religion of the Wild Goose Pagoda".
