"Wenhuang Laiji" in regular script is said to have been written by Chu Suiliang in the 23rd year of Zhenguan (649). Mi Youren, the son of Mi Fu in the Song Dynasty, believed that this work was the masterpiece of Chu Suiliang in his later years. Scholars in the past dynasties mostly believe that it is an ancient work by Mi Fu Lin in the Song Dynasty based on its brushwork and composition. There is an engraved version of "The Book of Mourning of the Emperor Wen" handed down from generation to generation, and this version is a double-hook and ink-filled version.
