In the "History of Contemporary Chinese Academic Thought" series，Dunhuang Studies Research Skills and History、Literature、Aesthetics、Legal studies and other studies are tied，Indicates that Dunhuang studies have become a very important academic field，The history bet365 Play online games has also become a very important history of academic thought。This is of great significance，In line with the achievements bet365 Play online games over the past 70 years，And its place in contemporary academic history。

"Study on bet365 Play online games in Contemporary China (1949-2019)" is a very heavy academic history monograph。Because bet365 Play online games include data collection, compilation and publication、Historical Geography、Economy and Society、Culture and Art、Language、Religious Technology，even the history of clothing、History of Craftsmanship、Cave archeology and conservation and many other fields，The diversity of disciplines and the complexity of results make it very difficult to write such an academic history。After 6 years of hard work by three authors represented by Mr. Hao Chunwen，Contributed such a great work to us，Deserves our sincere appreciation and admiration。

There are two other things worthy of admiration。First, the author’s understanding of this book、Strict requirements for one’s own high standards。"Postscript" of the book，He did not want to write this book as a "simple accumulation of theoretical names"，Said, "It would be better to compile a catalog of treatises"，So I didn’t hesitate to scrap the first draft and start over，Comprehensive revisions to the 20th century section，Partially rewritten for the 21st century。It is precisely because of such high standards，The book is to be written into a high standard of "an academic history that reflects the development of Chinese bet365 Play online games"，This makes the book of high academic value。Secondly, Mr. Hao Chunwen adopted a pragmatic attitude towards the positioning of the book。In "Postscript"，He divided the writing of academic history into four realms: the first is the catalog style，The second is the introductory form，The third is the academic history style，The fourth is the academic analysis formula。He believes that the book "can be between the second and third levels"，"Some people have also tried to approach the fourth realm"。This evaluation is very pertinent，This attitude of not boasting is also admirable。

In view of the above，The author does not want to list all the advantages of bet365 Play online games book，For example，Rich content、Appropriate method, etc.，Just a few of the more profound impressions。

First，As the "Postscript" says，The book hopes to achieve "a brief introduction to each book and paper involved in its specific contribution、Limitations and Problems”。Of course it is not easy to do this，Because it is impossible for the author to have research or in-depth understanding of every field involved in Dunhuang studies，Sometimes it’s impossible to tell where the contribution is、What are the limitations。But obviously the author is trying hard，Strive to achieve this goal。Mr. Hao Chunwen is the example。For example，Research on Equal Land System，In order to write this part well，He read through numerous treatises on the study of land equalization，sorted out the ins and outs of the relevant debate，So this part is written very solidly。Although the basic information for the study of land equalization is inseparable from Dunhuang documents，But the actual research goes far beyond the scope bet365 Play online games。Therefore，A review of the academic history of research on land equalization，Not only has the significance of the academic history bet365 Play online games，At the same time, it also has academic historical significance in the study of the land system history of the Tang Dynasty and even the economic history of the Tang Dynasty。Part about the research on equalization of land，can be classified into the third realm of academic history writing。The slight disadvantage is that after entering the 21st century，Especially after the discovery of "Tian Sheng Ling Tian Ling"，There are some more studies in the academic community，Not fully reflected。

Second，This book attempts to approach the fourth realm，This realm is reflected in at least two aspects。One is about the connotation bet365 Play online games、Exploration of definitions and properties。Although this section is placed in the 21st century section，But the actual discussion started from the term "Dunhuang Studies" in 1925，In fact, it is a theoretical argument about Dunhuang studies。There is an introduction、Analysis、Comments、Author’s opinion，It can be said that it has reached the "academic analysis", which is the fourth level。The other one is about the emerging Dunhuang Manuscriptology，The narrative starting point also begins in the 1970s，Combined the similarities and differences between "Dunhuang philology", "Dunhuang manuscript philology" and "Dunhuang manuscript philology"，And provide the author’s opinions，I think it is more reasonable to call it "Dunhuang Manuscriptology"。And based on this，From manuscript symbol、Manuscript dating、Written features、Distinguish the authenticity of the manuscript、The manuscript combines and discusses academic achievements。This is actually building a system of script studies，This is also close to the "academic analysis style" academic history writing。This book gives high praise to manuscript studies，Not only considers it an emerging field bet365 Play online games，Ascendant，And in the conclusion, it is summarized as a new paradigm and new perspective for Dunhuang studies。This summary has important guiding significance。However, it is a pity that this book does not give a place to "Chinese ancient literature"。In fact, "manuscriptology" was mainly proposed by literature researchers and language researchers，The purpose is to distinguish it from literary works such as engraved anthologies。In other words，Manuscripts are a concept opposite to engravings。But，Like expression ultimatum、Contract account books, etc. do not have the form of engravings at all，It seems inaccurate to say they are manuscripts。They are only instruments in a narrow sense，Studying these documents should use the perspective and methods of paleography。

　Third，The author of this book has a macro vision，One of the manifestations is the periodization bet365 Play online games。The whole book divides the study bet365 Play online games into four stages: 1909-1949 is the first stage，1949-1978 is the second stage，1978-2000 is the third stage，2001-2019 is the fourth stage。The author is very humble，Considers that this periodization is a "preliminary and immature view"，At the same time, I am also very concerned about the academic community’s opinion on whether this periodization is accurate。In terms of time，There should be no problem。From the nature，The author believes that the first stage is mainly the rising period，The second stage is the steady development and basic stagnation of the mainland，The pace of research on Hong Kong and Taiwan is accelerating，The third stage is a period of rapid development，The fourth stage is the period of transformation。This characterization of each period can be established。It should be pointed out that the fourth stage。The author believes that although the research on Dunhuang studies at this stage is still based on traditional topics and traditional methods、Paradigm-based，But a new perspective、New paradigms and new methods have emerged more and more，"So，We call Chinese Dunhuang Studies in the 21st century Dunhuang Studies in the transition period"。This reflects the author’s keen academic vision。Of course，What type is this transformation from?，It depends on future development。Reorganizing Dunhuang materials is also a transformation，After the full color version of all information is released，There will definitely be a new research boom，It’s also good to learn from writing，Paleography is also good，All will develop in depth on this basis。

　Fourth，The author of this book is sorting out the academic history bet365 Play online games，Full of a scholar’s ​​sense of academic responsibility and academic pride，Through the review of academic history，Drawed to very encouraging conclusions。“It is no exaggeration to say，Most of the frontier commanding heights of international Dunhuang studies are occupied by Chinese scholars，Mastered the leadership and voice of international Dunhuang studies。""By the end of the 20th century，Chinese scholars have not only reached world-leading levels in many important fields bet365 Play online games，At the same time, it also has the leadership and voice of international Dunhuang studies。”“In International Dunhuang Studies，Chinese scholars have more say and even dominance。”“Especially in the past forty years，Chinese scholars have launched world-recognized summative or groundbreaking results in various important fields of international Dunhuang studies，Mastered the leadership and voice in the development of international Dunhuang studies。" The author proudly said: "This is the pride of China，It also enhances China’s academic status in the world。”This is the most important conclusion reached by this book after sorting out the academic history bet365 Play online games，It will greatly enhance the academic confidence of Dunhuang scholars，Provide important academic historical support for the in-depth development bet365 Play online games in the future。

　Academic history research work done in the book "Research on Dunhuang Studies in Contemporary China (1949-2019)"，Through the connotation bet365 Play online games、Definition、Exploration of properties and classification and discussion，Provides strong support for the subject system bet365 Play online games；By sorting out the research fields at each stage、Research Methods、The evolution of research paradigm，Provides a solid foundation for the academic system bet365 Play online games；By focusing on commending the achievements and contributions of Chinese scholars，Provides a broad platform for constructing a discourse system with Chinese characteristics bet365 Play online games。

In short，The publication of this book is of great significance to Chinese bet365 Play online games，It has both summary and prospect significance，It is an academic history work with important academic value。Thanks again to the author and publisher of the book，Congratulations。
