The full name of the "Huangfu Birthday Monument" is "The Monument of the Emperor Zuo Guanglu of the Sui Dynasty", also known as "The Monument of Huangfu Jun". The inscription has twenty-eight lines, fifty-nine characters in each line, and fifty-nine characters in full line. Regular script is Ouyang Xun's work when he was young.
"Mo Lin Kuai Shi" states that this stele was erected in the Sui Dynasty and should have been written by Ouyang Xun in his early years. This stele was broken into two parts in the Ming Dynasty. There is no date when the monument was erected, but it is hidden in Xi'an, Shaanxi Province.
The Northern Song Dynasty rubbing of "Huangfu's Birthday Monument", the word "wu" in "Participate in the maintenance of machinery" is not damaged. The stele was broken due to the earthquake in the Wanli year of the Ming Dynasty, and the ones that were cut when it was cracked like a line are called the "line-broken version"; the ones where the words "jianranbin" and other characters are not missing are called the "three prisons version". Wenming Bookstore photocopied Weng Fanggang's approved edition, and Youzheng Bookstore photocopied Zhao Shijun's and Liu E's editions. Two rubbings from the Northern Song Dynasty are in the collection of the Palace Museum.
