Ou Yangxun (557-64 1) was born in Linxiang, Tanzhou (now Changsha, Hunan). Living in the Sui and Tang Dynasties, after the Sui Dynasty entered the Tang Dynasty, the rate of officials to princes was higher, and the rate of Ouyang was higher. Ou Yangxun's calligraphy was very popular in the Sui Dynasty. After entering the Tang Dynasty, he was appreciated by Tang Gaozu Li Yuan and admired by the calligraphy circle. He is one of the "four outstanding figures in the early Tang Dynasty". As they say, people think this is the law. Korea tried to send an envoy to ask him, and the emperor sighed:' He looks at his book and says that he looks burly? "("Old Tang Book "Volume 198" Biography of Ou Yangxun ") The so-called" self-naming concreteness "is often called" European style ". He deeply studied Wang Xizhi's calligraphy and extended it to the inscriptions of Jin people. It is said that once he was on a business trip, he saw the inscription of Suo Jing in the Jin Dynasty on the road. The more he watched it, the more reluctant he was to leave. He simply sat next to the memorial tablet and watched it for three days before he was reluctant to go on the road. Therefore, Ou Yangxun's calligraphy has become a family, combining the characteristics of this dynasty's tablet calligraphy in Wei, Jin and Southern Dynasties. Later generations have a lot of comments on his calligraphy. The Song Dynasty's "Xuan He Shu Pu" said that he was "full of energy in his later years" ... or he was surprised by the grass wrapped in a snake, and he was born in the clouds. As far as its brushwork is clever and its meaning is elegant, people are cut into four sides than the rise of a lonely peak. The commentator is not empty talk. Bao, a famous calligrapher in Qing Dynasty, praised his regular script as "realistic, incisive and balanced". "
Ou Yangxun has a deep research on calligraphy theory, including eight methods, thirty-six strategies, teaching strategies and brushwork. "Eight Tactics" tells eight kinds of stippling situations; Thirty-six plans are devoted to the rules of font structure; "Teaching tactics" is his own experience in practicing calligraphy. On the use of pens describes the methods of using pens since ancient times.
