The original books of the above 6 types have been lost long ago. They have been edited and edited by Sun Xingyan and included in the "Pingjin Library Series" and "Si Bu Yao" and other series. The upper and lower volumes of "Han Jiu Yi" were taken from the original version of "Yongle Dadian" published by Wuyingdian Collection in the Qing Dynasty. After Sun's proofreading, two volumes of "Supplement" were attached. Among the six types, "Old Rituals of the Han Dynasty" and "Official Rituals of the Han Dynasty" are the most important. "Old Rituals of the Han Dynasty" is dedicated to the Western Han Dynasty, focusing on the official system, and also describes the emperor's daily life, the queen's silkworm kisses, rituals, funerals of the emperor and princes, and other miscellaneous matters. The remaining five types only record the official system of the Han Dynasty. Although these six types of books are not complete, they are still important materials for discussing the official and ritual systems of the Han Dynasty.
