一，Since the country proposed the “One Belt, One Road” initiative，Silk Road research is quietly heating up。bet365 sports, located on the strategic route of the Silk Road, has become a top priority in Silk Road research。In order to cater to the new academic trend of the times，The "Updated Edition" adds "the opening of the Silk Road" when describing the history of bet365 sports during the Qin and Han Dynasties，When describing the history of bet365 sports during the Sui and Tang Dynasties，Change the section "The Prosperity of Sino-Western Communications" in the previous edition to "The Prosperity of the Silk Road"。This addition，It not only highlights bet365 sports’s important geographical location on the Silk Road，It also clarifies bet365 sports’s role as a bridge in communicating between Chinese and Western civilizations，And the huge impact of multiple civilizations on bet365 sports。

　Second，The birth of the term "bet365 sports Studies" has been a hot topic in bet365 sports academic circles in recent years。Currently，The academic community has basically reached a consensus，Though the term "bet365 sports Studies" was first proposed by Japanese scholar Ishihama Juntaro，But the impact is not big。1930，Mr. Chen Yinke also independently proposed the name "bet365 sports Studies"，Widely recognized and used because of its great influence。For these discussions，The "Updated Edition" absorbs the latest achievements，State that Chen Yinke is the first domestic scholar to propose "bet365 sports Studies"。

　Third，The cliff face of Dunhuang Mogao Grottoes consists of the southern section and the northern section。Caves with colorful sculptures and murals are mainly distributed in the Southern District，So it is called a place for worshiping Buddha，The function of the caves in the North District has not been clear for a long time。1988-1995，Dunhuang Academy conducts archaeological excavations of the caves in the northern area of ​​Mogao Grottoes one by one，Finally found out that the North District is used as a monk’s cave、Meditation Cave、嘗门、The nature and function of caves, etc.，524 more multilingual documents found。It can be said，The archeology of the northern area of ​​Mogao Grottoes is the highlight of Dunhuang’s work in the past 30 years，The archaeological reports and research results published subsequently are masterpieces bet365 sports。The "Additional Edition" introduces the art of Dunhuang Grottoes，Timely addition of "New Archaeological Discovery in the North Area of ​​Mogao Grottoes"，To enable readers to understand the major archaeological gains in Dunhuang in recent years，And a more complete understanding of the nature and function of the Dunhuang Mogao Grottoes。

　Fourth，The reason why the Dunhuang Scripture Cave is closed has always been an unsolved mystery bet365 sports。Despite hundreds of years of heated debate, there is still no conclusion，Persistent Dunhuang scholars never give up，In recent years, viewpoints such as the "Exclusion of Bo thought theory", "Buddhist support theory" and "Moddha thought theory" have been put forward。The "Updated Edition" keeps up with hot topics，Actively add relevant information，To keep readers abreast of the latest academic developments in this field。

　Chapters are divided into sections to simplify bet365 sports questions

​​The scientific classification and brief names of chapters greatly enhance readers’ reading interest。The "Updated Edition" has sections under the chapters，Make the directory more standardized。And，Almost every question has been simplified to varying degrees，If the original "three" in the first chapter is、Hua Rong handed over a city - the history of bet365 sports art、Cultural Background" was changed to "Section 3: bet365 sports during the Wei, Jin, Southern and Northern Dynasties"；"四、A Pearl on the Silk Road—bet365 sports in the Sui and Early Tang Dynasties" was changed to "Section 4: bet365 sports in the Sui and Tang Dynasties", etc.。The deleted section titles are concise and to the point and reflect the logical relationship between each other。

Although the style and content of the "Additional Edition" have not undergone qualitative changes，But the quantitative change is obvious。Especially the Dunhuang history part in Chapter 1，Completely changed the original "middle drum，Thin at both ends”，That is, the content between Han and Song Dynasties is more detailed，Disadvantages of simpler history before the Han Dynasty and after the Song Dynasty。In the Sui and Tang Dynasties，Added section "Emperor Sui Yang's management of Hexi and Zhangye mutual trade"，Make the context of the revitalization of the Silk Road clearer。When describing Dunhuang’s religious classics and religious beliefs in Chapter 4，New section "Zoroastrianism"，Together with Nestorianism and Manichaeism, it is called the Sanyi Religion。We know，Compared to Nestorianism and Manichaeism，In ancient Dunhuang，There are more followers of Zoroastrianism、Greater influence，So，It is very necessary to supplement its content。Also，When describing Chapter 3 "Japanese Dunhuang and Turpan Documents" in the 2002 edition of "General Theory bet365 sports"，Only focuses on the collection of Ryugu University，For other institutions click here。The "Updated Edition" describes in more detail the origins of collections from more than ten institutions such as "Tokyo and Kyoto National Museums", "Calligraphy Museum" and "Fujii Yurikan"、Value and research status, etc.，Not only allows readers to fully understand the status of Dunhuang documents collected in Japan，It also makes it easier for readers to find accurate information，Carry out academic research。The author is checking for omissions and filling in the gaps，Also drastically remove red tape，Make the style and content more reasonable and compact。As ​​Chapter 2 introduces Dunhuang art，Deleted the original two sections of Feitian and Music and Dance，Focus on the murals in Dunhuang、Colored Sculpture and Architecture。
