Ouyang Xun (557～641), courtesy name Xinben, was born in Linxiang, Tanzhou (now Changsha, Hunan). In the Sui Dynasty, he was a doctor of Taichang, and in the Tang Dynasty, he was the prince's commander, and he was a bachelor of Hongwenguan. "Jiucheng Palace Liquan Ming" Ouyang Xun was granted the title of male from Bohai County. He was a famous calligrapher in the early Tang Dynasty and ranked first among the four major calligraphers. He was also known as "Ou Yu" together with Yu Shinan. The original biography of "Book of Tang" says that he "initially imitated Wang Xizhi's calligraphy, but later surpassed it, because he named himself his style. What he taught was regarded as a method." He is good at talking about structure, and his treatises such as "Thirty-six Methods" have been handed down. His font structure is very precise and is known for its "precipitous" style. When later generations learn to calligraphy, they mostly start with Lin's characters. The representative work is "Jiucheng Palace Liquan Ming". It was carved in the sixth year of Zhenguan (632). There are also "Huadu Temple Stele", "Huangfu Birthday Stele" and so on. The ink inscriptions handed down from ancient times include "Meng Dian Tie", "Bu Shang Tie", "Zhang Han Tie", etc.
