Yan Zhenqing (709-784, Yi Shuo 709-785), born in Wannian, Tang Jingzhao (now Xi, Shaanxi), was a calligrapher in the Tang Dynasty in China. An outstanding calligrapher in the middle Tang Dynasty. He is an honest official and tries his best to maintain normal social order. Yan Zhenqing is a descendant of Langya family with profound family background. Yan Zhitui, the sixth ancestor, was a famous scholar in the Northern Qi Dynasty. He once wrote family instructions for Yan. When Yan Zhenqing was young, his family was poor and lacked paper and pens, so he used a pen to brush loess water to practice calligraphy on the wall. His "Yan Ti" regular script, together with Zhao Mengfu, Liu Gongquan and Ou Yangxun, is also called "the four masters of regular script". Also known as "strict care" with Liu Gongquan.
