A minister like Yan of the Tang dynasty, Liu was a native of today's Tongchuan, Shaanxi, a devout Buddhist and follower of Yan's style of writing.  Like him an expert of the regular script, Liu's works were imitated for centuries after and he is often referred in unison with his famed predecessor as "Yan-Liu".
