In 1999, Mr. Dai Jianguo published the news and related papers on the discovery of the 3737935 of the "Heavenly Holy Order" (Ten Residual Volumes) of the Northern Song Dynasty, which had been lost for thousands of years, which caused great shock in the historical circles of the Tang and Song Dynasties and the legal history circles of the Tang and Song Dynasties. In October 2006, the Tianyi Pavilion Museum and the Tiansheng Ling Collation Topic Group of the Institute of History of the Chinese Academy of Social Sciences officially published the "Tianyi Pavilion Hidden Banknote Tiansheng Ling School Certificate (with Tang Ling Restoration Research)" (hereinafter referred to as "Tiansheng Ling School Certificate"), which provided the academic community with a photocopy of the Tiansheng Order, a preliminarily sorted out proofreading and a clear version, and at the same time provided the original Tang Ling text after the restoration of the Song Ling in the Tiansheng Order to the Tang Order, for scholars to study and use. As the collator of the Heavenly Sacred Order, we found that the Heavenly Sacred Order had important academic value and deserved serious study, so as soon as the collation work was completed, we devoted efforts to conducting preliminary research on some particularly noteworthy issues, and concentrated the results in the twelfth volume of Tang Studies published in December 2006. Next, the members of our collation team continued to work hard and applied for key courses at the academy level of the Chinese Academy of Social Sciences, and then within two years, they conducted a more detailed study of the "Heavenly Holy Order", including: 1. The relationship between the legal form of the "Order" and the law, character, form, and edict. 2. A study of the Tang and Song dynasty systems mentioned in each decree. 3. Re-discussion of certain omissions in the "Heavenly Holy Order School Certificate". The first aspect of research mainly involves the inclusion of "edicts" in the order, as well as the relationship between the "edict" and the form of the edict, and the age of the edict. There are disagreements not only in the academic circles but also within the members of our collation group regarding the age of the Tang Decree attached to the Heavenly Holy Order, so the various parts and chapters in the book will have different expressions on this: some refer to it as the 25th Decree of the Kaiyuan Dynasty, while others are skeptical and only call it the "Kaiyuan Order" or "Tang Order". The second aspect of research covers a wide range of areas, including inheritance, especially the "transmission" and "transmission" system, the system of passing through, the warehouse system, the system of giving grain in Dingzhong, the system of female doctors and medical officers being enrolled, the vacation system, the camping system, the funeral system (including the relationship between the order and the ceremony), and the system of people of color. These institutional studies are based on new data provided to us by the Heavenly Order, showing the great value of the Heavenly Order in terms of historical materials; At the same time, the research often involves the comparison of the "Tang" and "Song" or "Tang" and "Japanese" systems, which fully demonstrates the great value of the Heavenly Holy Order in studying institutional changes and system comparisons. The third aspect involves various issues such as sentence breaking, punctuation, word understanding, and article restoration in the "Heavenly Holy Order School Certificate". Of course, these three aspects are not completely separated, and some studies include two or even three of them at the same time. In this way, through everyone's thinking, discussion, inquiry, writing, and participation in various academic conferences (such as the 10th Annual Meeting of the Chinese Tang History Society in Shanghai in November 2007; In May 2008, he participated in the 53rd International Conference of Oriental Scholars in Tokyo; In June 2008, together with the School of History of Renmin University of China and the Editorial Board of Tang Studies, he hosted a seminar on "Heavenly Sacred Order" in Beijing; In July 2008, he participated in the seminar "Ancient Capital Chang'an and Sui and Tang Civilization" in Xi'an; In October 2009, he attended the second meeting of the 10th Annual Conference of the Chinese Tang History Society in Chongqing; In November 2009, we participated in the "New Historical Materials, New Perspectives, New Perspectives: International Academic Symposium on the Heavenly Holy Order" in Taiwan, etc.), listening to scholars' opinions and supplementing and revising, and we completed this research work of more than 400,000 words. It can be said to be a stage result of our task group's research on the Heavenly Holy Order. We are willing to provide it to the academic community to promote further in-depth study of the Heavenly Sacred Order and even the related Tang and Song systems. It should be noted that many of the texts included in this book have been published in other journals or paper collections, but due to listening to opinions at conferences and absorbing the opinions of experts at the end of the course, these texts have been revised to varying degrees when included in this book. This modification takes two ways: one is to directly modify the original text; The second is to use the form of "notes" to display the opinions on revision in a centralized manner, while the original text is basically unchanged. Since we published our first results in 2006, the academic community has published numerous research articles on the Heavenly Sacred Order. Some of these articles deal with the Heavenly Order Certificates and our papers, and we have tried to absorb the opinions in these articles and reflect them in this book. In addition, in terms of style, it should be noted that: First, when this book mentions the title of the "Heavenly Holy Order", although it is basically unified as "Heavenly Sacred Order ×× Order", there are still different expressions such as "Kaiyuan (25) "×× Order", "Ming Ben Kaiyuan "×× Order", and so on. This is because everyone's understanding of the Heavenly Order is slightly different; Sometimes, it is also because of the problems mentioned in the article that it is necessary to emphasize certain nature of the Order. 2. When quoting the text of the Heavenly Holy Order, the text of the note is changed to a single-line small print (one character smaller than the text of the text). If there is text added by the author, it is enclosed in parentheses. 3. The annotations of the articles of the "Heavenly Sacred Order" are roughly unified into the following three 3737936: 1. The first half of the Decree is "right and because of the old text, with a new reference", that is, those we call the "Song Order" are marked with the "Song ××" article. 2. In the second half of the decree, "Right Order does not work", that is, what we call "Tang Order" is marked with "Tang ××" article. 3. Those who restore the first half of the "Song Order" as the Tang Order, and mix it with the attached "Tang Order" in the second half, and become a complete restoration of the "Tang Order", shall be marked as "Restoration of the Tang Order" Article ××" or "Restoration of the Tang Dynasty ×× Order Article ××". At the same time as this book was completed, the researchers in our subject group also developed other research topics. We will continue to study, and it may not be so far that a second or more research book will come out. Research practice has proved that the Heavenly Holy Order has great research value and is worthy of continuous and in-depth research by the academic community. We are willing to continue to work hard in this research trend, and work with all colleagues in the academic community who care about and study the Heavenly Holy Order to fully explore the value of the Heavenly Holy Order to promote the progress of the study of Tang and Song history. Scholars who participated in the writing of this book were: Song Jiajiao, Wu Lihuan, Huang Zhengjian, Li Jinxiu, Niu Laiying, Meng Yanhong, Zhao Daying, and Cheng Jin. For the specific compilation and chapter of the writing, see the signature in the Head. Although the book has been written in a variety of styles, each author is very happy to hear critical opinions from readers and academics. Huang Zhengjian, December 2009（AI翻译）
