Yan Zhenqing was a calligrapher in the Tang Dynasty.

Yan Zhenqing (709-785) was born in Jingzhao (now Xi 'an). In the "An Shi Rebellion", he was highly valued by the court for resolutely resisting thieves in Pingyuan County. He has served as the official minister and the criminal minister, and is called the first of strictness by the world. During the Dezong period, Li Xilie rebelled, and Yan Zhenqing put the country first, went to the enemy camp, stopped the thief when he knew what was right, and was finally slapped to death. Yan Zhenqing, the calligrapher with the highest achievement and the greatest influence after Wang Xizhi, became an important milestone in China literati calligraphy. He sought advice from many teachers and became a Buddha, creating an aesthetic paradigm of regular script calligraphy, which is solemn, simple and magnificent. His cursive script also conveys a calm, happy, bold and free and easy master atmosphere. There are many inscriptions handed down from ancient times, such as "Sacrifice to My Nephew", "Fight for Seats" and "Ma Gubei".
