When the academic community is studying in depth the important speech of General Secretary Xi Jinping "Introducing in-depth research on the history of Chinese civilization and enhancing historical consciousness and strengthening cultural confidence"，We can’t help but remember our long-term commitment to the study of ancient Chinese civilization，Leading and promoting ancient Chinese history、Archaeology、bet365 withdrawal. Li Xueqin who developed paleography and other disciplines。

bet365 withdrawal. Li has been away from us for more than 3 years，Reading the book "Lecture Notes on "The Chronicles of the Five Emperors" and "The Chronicles of Xia" (Tsinghua University Press, March 2022 Edition) carefully compiled by later scholars，It "refines Xia, Shang, Zhou and Han，100-year journey，Jueweishiguweixianjue；Dao Guan Li Yi Shi Shu，Renewal of lost articles，The academic spirit of "writing history and passing on classics to future generations"，Inspiring generations of scholars to pass on the legacy。Reviewer of this book、Professor Liu Guozhong from Tsinghua University Unearthed Documents Research and Protection Center，is leading an academic team，Carefully organize the series of lecture notes given by bet365 withdrawal. Li at Tsinghua University。

　　bet365 withdrawal feast should not be buried in future generations

"China Social Sciences Journal": The publication of "bet365 withdrawal. Li Xueqin's Tsinghua Lecture Series" is very exciting。Please introduce the reason for publication、Purpose and work plan。

Liu Guozhong: bet365 withdrawal. Li attaches great importance to talent cultivation。He often says，As a university professor，If you don’t attend class，That’s outrageous。Since 2005，In addition to supervising graduate students，Proactively offer open courses every semester，And the content taught is never the same，Attracted young teachers from various universities and scientific research institutions in Beijing、Scientific researchers and students came to listen，Some scholars from outside Beijing will also come from afar。Due to "overcrowding" during class，Even "alarmed" the academic affairs department of Tsinghua University。

bet365 withdrawal. Li has taught many courses in his 7 years of teaching，If these wonderful courses are not organized and disseminated in written form，Let more people benefit from it，It is undoubtedly a pity。In view of this，Led by Tsinghua University Unearthed Documents Research and Protection Center，Preparing to compile and publish bet365 withdrawal. Li’s various lecture notes at Tsinghua over the years。This series of lecture notes is compiled based on the video and audio materials recorded during bet365 withdrawal. Li’s lectures，In order to maximize the original appearance of the scene and the teaching effect。At the same time，Publication of book series，It is also to better inherit and carry forward bet365 withdrawal. Li Xueqin’s academic thoughts and achievements。

"Lecture Notes on "The Chronicles of the Five Emperors" and "The Chronicles of Xia"，It is bet365 withdrawal. Li who accepted the appointment of the China Cultural Forum，Taught the teaching content of the two documents "The Chronicles of the Five Emperors" and "The Chronicles of Xia" in "Historical Records" in 2007 and 2012 respectively。One of the "Lecture Notes on "The Chronicles of the Five Emperors"" was named "Lecture Notes on "The Chronicles of the Five Emperors"" in 2012，Published by Life·Read·New Knowledge Sanlian Bookstore，When this series is included，We checked it all again based on the recording data at that time，Supplemented and revised some lecture notes。As for "Lecture Notes on "Xia Benji""，has never been officially compiled and published before。Except for this lecture，Next we will compile and publish bet365 withdrawal. Li’s oracle bone science、Bronze、Lecture notes on bronze inscriptions and other aspects。

《China Social Sciences Journal》: What do you think，Which of bet365 withdrawal. Li’s academic propositions have had a profound impact on the academic world？

Liu Guozhong: The three propositions put forward by bet365 withdrawal. Li have a profound impact on the academic world。First, re-evaluate ancient Chinese civilization。This is an important insight he put forward at the second symposium on pre-Qin history in 1981。The core content is that traditional concepts often estimate ancient Chinese civilization relatively late、Relatively low，Therefore it is necessary to combine scientific research with archaeological results and documents，Making a realistic re-evaluation of ancient Chinese civilization。

The second is to get out of the era of doubting the past。This is an important proposition put forward by bet365 withdrawal. Li in 1992，The basic point is that although the trend of doubting antiquity that was prevalent in the 1920s had great progressive significance，But it also creates a climate of suspicion about the incorrectness of ancient books and ancient history，Causing many “unjust, false and wrongful convictions”，We should get rid of some old views now，Combining documentary research with archaeological research，Out of the age of doubt。

The third is to rewrite academic history。This is also an important opinion put forward by bet365 withdrawal. Li in the 1990s。The historical background is: due to the discovery of a large amount of archaeological data，Especially the continuous unearthing of bamboo and silk documents，Making many views on pre-Qin academic history have to be changed，And this involves the need to reconsider the academic thoughts of the Han, Tang, Song, Yuan, Ming and Qing dynasties and even in modern times，Therefore，bet365 withdrawal. Li advocates rewriting academic history。This idea，Revaluation of ancient Chinese civilization、The views on emerging from the age of doubt are of the same origin。

　　The “original land” where legend exists and has bet365 withdrawal facts

"China Social Sciences Journal": bet365 withdrawal. Li once presided over the Xia, Shang and Zhou dynasty project，What does this have to do with the Chinese Civilization Discovery Project，What are the results achieved so far？

Liu Guozhong: The Xia, Shang and Zhou Dynasty Project truly combined natural sciences with humanities and social sciences for the first time，In a multidisciplinary approach，Concentrate your strength、Joint research。9 topics based on system engineering methods，There are 44 topics set under these topics，Involving history、Archaeology、Astronomy、Four subject categories of scientific and technological dating。bet365 withdrawal. Li is one of the four chief scientists of the project，Also serves as the leader of the expert group，In overall project design、Played a core leadership role in organizing key research and the entire process of integrating and publishing results。He cooperates with many experts and scholars，Creating democracy、Equal academic atmosphere of joint research，At the same time, it puts forward a series of new insights and questions on many academic problems，Made important contributions to the successful realization of research goals。2000，"Xia, Shang and Zhou Dynasty Project 1996-2000 Stage Achievements Report·Simple Version" published。After the project is completed and passed the acceptance，As a scientific research，The main work in the later period focused on the central task of compiling the complex version of the "Xia, Shang and Zhou Dynasty Engineering Report"。In this process，bet365 withdrawal. Li not only presided over the writing，And based on the work of the drafting group，Written in the late Shang Dynasty、Compilation and revision of the parts of King Wu’s defeat of Shang and Western Wednesday。What a pity，bet365 withdrawal. Li did not see the official publication of the traditional version of the dating project report during his lifetime，The book was successfully released some time ago。This achievement laid a solid foundation for the development of Xia, Shang and Zhou chronology，Provides an important opportunity to carry out more research on the basis of chronology。

The Chinese Civilization Discovery Project is based on the Xia, Shang and Zhou Dynasty Project，Another multidisciplinary comprehensive research project supported by the state，It can be said to be the continuation and deepening bet365 withdrawal Xia, Shang and Zhou dynasty project。The purpose bet365 withdrawal Chinese Civilization Discovery Project is: multidisciplinary、Multiple angles、Multiple levels、Comprehensive study bet365 withdrawal origin of Chinese civilization、The process of formation and early development，And explore the context that shaped this process、Reason、Development path and its characteristics。It uses archaeological investigation and excavation as the main means to obtain relevant information，Supported by modern science and technology，Adopt a multidisciplinary and interdisciplinary research approach，Thus revealing the origin and early development bet365 withdrawal Chinese nation’s 5,000-year civilization。The origin of Chinese civilization from the Chinese Civilization Discovery Project、Formation、Historical context of development，On the formation and development process bet365 withdrawal pluralistic unity of Chinese civilization，On the characteristics of Chinese civilization and the reasons for its formation, etc.，They all have a clearer understanding。As General Secretary Xi Jinping emphasized when presiding over the 39th collective study session bet365 withdrawal Political Bureau bet365 withdrawal CPC Central Committee: "The Chinese Civilization Discovery Project has achieved remarkable results，But there is still a long way to go，Must continue to advance、Continuously deepening。”

"China Social Sciences Journal": We often say that we are descendants of Yan and Huang，But Emperor Yan、The Yellow Emperor is considered a legendary figure。How does bet365 withdrawal. Li understand mythology、Ancient history presented in legends？

Liu Guozhong: Legends about Emperor Yan and Emperor Huang，And the rich content of Huangdi culture，Related to the tradition of the Chinese nation，It is also related to the national centripetal force of overseas Chinese、Cohesion，It is also related to the rejuvenation of the entire Chinese nation。But how to know Emperor Yan、Legends about the Yellow Emperor，Scholars have great differences。bet365 withdrawal. Li for Yan、Huang Chuanhuan has his own understanding。He specifically pointed out in articles such as "The Legend of the Yellow Emperor Must Have a Historical "Plain Land"，Sima Qian was writing "Historical Records"，Written "The Chronicles of the Five Emperors" based on ancient classic documents，His attitude is very rigorous。Since Sima Qian wrote history so seriously，Why are there so many myths and legends in "Historical Records"？bet365 withdrawal. Li agrees with bet365 withdrawal. Wang Guowei’s opinion in this regard，I think studying ancient history is a very difficult thing，Because it is inevitable that history and myths and legends will be combined，There are elements of mythology in ancient history，There are also many historical facts，In other words，All legends must have a historical background。This situation is not limited to China，It is the same in all countries in the world。For example, there is a pioneer in European archeology——Henry Schliemann，He has been fascinated by "Homer's Epic" which was considered a myth at that time since he was a child，Believe that the Trojan War must have real content。So after he succeeded in business, he immediately turned to archeology，The ancient city of Troy was discovered as a result，A sensation all over the world。

Through the analysis of the relationship between legends and historical facts，bet365 withdrawal. Li proposed，The legend of the Yellow Emperor is very important，Same as the origin of other ancient civilizations in the world，There is also a background combined with mythological elements，It contains both myth and historical fact，Cannot be written off in one stroke。He further believes，Legends are an integral part of history，And it is an integral part of history。This insight greatly improved Yan、The importance of Huang and other ancient historical legends to the study of ancient civilization。

　　"bet365 withdrawal, bet365 withdrawal"

"China Social Sciences Journal": Please share with us some fragments of bet365 withdrawal. Li's academic process。

Liu Guozhong: The so-called "all roads lead to Rome"，Only by taking the right path can you reach your goal。If there was only one way to study historical issues，Like we only have one way，Due to missing reference，Unable to correct deviations or even errors。bet365 withdrawal. Li has a broad academic field，Has made groundbreaking contributions in many disciplines。He confessed，The field in which one is devoted often gives people the impression of being too complex，But taken together，It is a period of early civilization in Chinese history，roughly similar to the upper and lower limits of "Historical Records"。This field has an interdisciplinary and comprehensive nature，He calls it "research on ancient Chinese civilization"。

bet365 withdrawal. Li always talks about knowledge from the shallower to the deeper、Tracing the source，The word "diligence" best reflects his academic attitude and academic spirit。In college days，bet365 withdrawal. Jin Yuelin praised him for having the qualities of a philosopher。bet365 withdrawal. Li has a circle on the outside and a square on the inside，Be generous in dealing with others，But have the courage to stick to your own opinions in academic matters。He likes to use an English proverb "some everything"，Some of everything” to explain your academic experience。"Something" means that to learn something, you must understand everything that exists in this field；“Some of everything” means that you should also know some knowledge in other fields。So，"Half Academic History，A bet365 withdrawal. Li’s comment couldn’t be more appropriate。

bet365 withdrawal. Li is also an outstanding educator。His students come from all over the world、All walks of life、Domestic and foreign，And there are specialties in the art，Existing research history、Archaeology、Literature、Jianbo、Ancient characters、Language and Philosophy、Literature、Art、Law、Nationality、Religious，Also studies astronomy、Geography、History of Natural Science and Technology。So，We often say，Put bet365 withdrawal. Li’s students together，In order to show the full picture of his scholarship。

bet365 withdrawal. Li likes to communicate with young students，Love class。He answers all kinds of questions from students or readers who have never met him，Always answer patiently。Once he helped a stranger find information，Climbing the escalator to look for books at home，Accidentally fell from the escalator，Fortunately nothing serious。When we disciples encounter difficulties in study，He also often helps us collect information，Correction，Write it on a note and hand it to us quietly。

bet365 withdrawal. Li’s dedication to academic research is worthy of learning by future generations of scholars。He writes books and talks all his life，Dedicated all his life to his cherished academic career。Until illness and hospitalization，Things he never forgets every day，Still a research work on ancient Chinese civilization，This kind of academic undertaking for the motherland，Love and awe of Chinese civilization，Isn’t it what each of us needs to inherit？Tsinghua Jane Protection hosted by bet365 withdrawal. Li、Compilation and research business，is a highlight of his scientific research work in his later years，Tsinghua Jian has become synonymous with bet365 withdrawal. Li in a certain sense。More than ten years，bet365 withdrawal. Li collected the bamboo slips for Tsinghua University、Organization、A lot of effort and energy have been put into conservation and research work。As the importance of Tsinghua University slips continues to be revealed，bet365 withdrawal. Li’s academic contributions will definitely be remembered even more。

In addition，The reason why bet365 withdrawal. Li has achieved many academic achievements，Closely related to his scientific research methods。He perfectly realized the organic combination of knowledge and expertise，Focus on combining multidisciplinary knowledge in the research process，Integration of Chinese and Western，Connecting ancient and modern times，Zhaweizhizhu，Zonghengmaohe。bet365 withdrawal. Li has too much experience in his academic studies，We need to summarize！
