Ou Yangxun (557-64 1) was born in Linxiang, Tanzhou (now Changsha, Hunan). The famous calligrapher Ou Yangxun, Yu Shinan, Chu Suiliang and Xue Qi are also called "four schools in the early Tang Dynasty". Ou Yangxun's "Ou Ti" regular script, together with "Yan Ti" (Yan Zhenqing), "Liu Ti" (Liu Gongquan) and "Zhao Ti" (Zhao Mengfu), is called "the four regular scripts in the history of China calligraphy".

The story about Ou Yangxun is mainly recommended as follows:

First, about life experience and being an official.

Ou Yangxun was born in a noble family, and his father Ouyang Yi went to Guangzhou to be a secretariat during the Chen Dynasty.

The novel Biography of the White Ape in the early Tang Dynasty wrote such a story: Ouyang Yang's wife went south with her husband and was captured by the white ape on the way. Ouyang Yi found his wife and killed the white ape. When his wife came back, she gave birth to a son, Ou Yangxun. Therefore, Ou Yangxun is ugly.

This story was used by the Tang people to denigrate Ou Yangxun. Because Ou Yangxun is thin and looks like an ape ("thin and ape-like"), someone slandered him under a pseudonym at that time.

His father Ouyang was later killed for treason. According to the criminal law at that time, his son Ou Yangxun should be included in the collective punishment. Ministers of the Chen Dynasty regarded President Jiang and Ouyang Gui as old friends, so they adopted Ou Yangxun and he survived.

After the demise of the Sui Dynasty in 589, the 32-year-old became an official of the Sui Dynasty, working with the general manager Jiang. Tang Gaozu Tang Gaozu was a close friend of Ou Yangxun before he proclaimed himself emperor. After Li Yuan established the Li Tang Dynasty, Ou Yangxun also became an official of the Tang Dynasty, which was highly valued by Li Yuan and Li Shimin. During the Zhenguan period of Emperor Taizong, together with Yu Shinan and Feng Chengsu, he was awarded a bachelor's degree in Hong Wen Pavilion, the highest scholar at that time, specializing in teaching calligraphy. Later, Ou Yangxun was appointed as the Prince, and he was promoted to Doctor Guanglu of Yin Qing, and was made the Duke of Bohai. Therefore, later generations also called him "Ouyang Lvgeng" and "Ouyang Bohai".

Ou Yangxun was praised as a first-class calligrapher by Emperor Taizong and Li Shimin. He was invited to write his masterpiece "Literature and Art Collection" with Pei Ju and Chen He, with a total volume of 100.
