The Tang Dynasty was the peak of China's political, economic and cultural development, and the art of calligraphy entered a golden age. "At the beginning of the Tang Dynasty, four schools advocated the flourishing style of calligraphy in the Tang Dynasty, and Ou Yangxun and his calligraphy were the first of the four schools, which were precious in the history of China's calligraphy with their combination of various styles. Ou Yangxun (557-64 1), a calligrapher, was born in Linxiang, Xiangtan (now Changsha, Hunan). He was awarded the bachelor's degree of Ouyang Lvgeng in Hong Wen Pavilion. Ou Yangxun is smart and diligent, dabbling in classics and history, and having extensive knowledge and memorizing. He began to learn from Wang Xizhi's books, and later added ancient calligraphy to his teachings, which was unique and was regarded as a standard by later calligraphers and handed down as "European style". " The old Tang book "Call it" is dangerous and powerful, which is necessary. People received their letters, and they thought it was a model. "There are many works handed down by Ou Yangxun. The most famous ones are: Huangfu Birthday Monument, Jiuchenggong Liquan Ming, Huadu Temple Yong Zen Master Fota Ming, Yugong Wenyanbo Monument, all in block letters; Running script ink includes Zhong Ni Monti Tie and Shang Bo Du Shu Tie. In addition, his cursive "Thousand Characters" is also varied, graceful and wonderful.
