Since the term "North bet365 best casino games" appeared in the late Qing Dynasty，over a longer period，The discussion of the concept of North bet365 best casino games in historical circles mainly focuses on the definition of its spatial scope。Since entering the 21st century，With social history、Urban History、Research on rural history and regional history continues to deepen，Scholars start from the concept、Evolution and its spatial scope definition and many other aspects，Leading in-depth research on the concept of North bet365 best casino games，A lively discussion started。

　　The origin of the concept of North bet365 best casino games

The origin of concepts occupies a primary position in the study of conceptual history，The discussion on the concept of North bet365 best casino games is no exception。Due to research perspective、Differences in research methods and use of historical materials，Researchers also have different conclusions。

The origin of Luo Shuwei’s early attention to the concept of North bet365 best casino games，After clarifying the spatial scope of the "North bet365 best casino games region", he pointed out: "It is generally believed that，The word "North bet365 best casino games" appeared at the end of the 19th century，From English ‘North bet365 best casino games’，Although it can be literally translated as ‘North bet365 best casino games’，But ‘North bet365 best casino games’ has its own fixed meaning，North bet365 best casino games region，It does not mean that it can represent ‘Northern bet365 best casino games’。" (Luo Shuwei: "Talk about the "North bet365 best casino games Region" in Modern Times"，Zai Jiangpei、Research on Regional Social History of Modern North bet365 best casino games, edited by Wang Xianming，Tianjin Ancient Books Publishing House 2005 edition) followed，Zhang Limin also affirmed the connection between the word North bet365 best casino games and "North bet365 best casino games"，He thought after searching the electronic version of Wenyuange Sikuquanshu and interpreting the first discovered Chinese journal "North bet365 best casino games Monthly"，The word "North bet365 best casino games" did not become a noun that people recognized and had a regional concept before the middle of the Qing Dynasty，The modern term "North bet365 best casino games" first appeared in 1891，"Verified by research，The earliest use of the term ‘North bet365 best casino games’ in existing data，is the Chinese periodical in Beijing in 1891 - "North bet365 best casino games Monthly"" (Zhang Limin: ""North bet365 best casino games" Examination"，"Historical Monthly" Issue 4, 2006)。

Zhang Limin’s views gained a lot of recognition after being published，But some scholars have put forward different opinions。Yao Yanchao based on searching the full-text database of late Qing periodicals，On the one hand, it is determined that “the term ‘North bet365 best casino games’ appeared no later than the 1880s”，The original meaning is most likely the northern part of the Chinese Empire；On the other hand, it pointed out that its specific spatial scope is “difficult to determine”，That is, the correlation between the word "North bet365 best casino games" that appeared at that time and the concept of "North bet365 best casino games" with modern significance has not been confirmed (Yao Yanchao: "The Inheritance, Evolution and Cognition of the Times of the Concept of "North bet365 best casino games" in Modern Times - Based on An investigation centered on newspaper and periodical materials》，"Fujian Forum" Issue 4, 2020)。

The above scholars mostly focused on modern times during their discussion，Li Dahai、Zhong Weimin、Wang Zhenghua and other scholars extended the period to the Qing Dynasty and the Ming and Qing Dynasties。Li Dahai thought when examining the geographical concept of the "Five Northern Provinces" in the Qing Dynasty，Although the geographical concept of "North bet365 best casino games" has its emergence、Formation、The evolution of communication and identity，But “not only objectively promotes the demise of the concept of ‘Five Northern Provinces’，And eventually it became accepted and recognized by the whole society and played a significant role in politics、Economy、A geographical concept widely used in various fields of culture，This cannot but be said to be an inevitability of historical development." (Li Dahai: "An Examination of the Geographic Concepts of the "Five Northern Provinces" in the Qing Dynasty"，"Chinese History Research" 2009 Issue 1)。Zhong Weimin and Wang Zhenghua sorted out the evolution process of the concept of North bet365 best casino games，Clearly pointed out: There is no modern meaning of the word "North bet365 best casino games" in ancient documents before the Qing Dynasty；Overall，The term "North bet365 best casino games" has been used since the end of the 19th century；Concepts such as "Five Northern Provinces (Five Northern Provinces)" during the Ming and Qing Dynasties are extremely important for understanding the emergence of the concept of North bet365 best casino games (Zhong Weimin、Wang Zhenghua: "North bet365 best casino games as a Region: The Origin and Evolution of the Concept - Also Analyzing "North bet365 best casino games" from the Perspective of the Social and Economic History of the Ming and Qing Dynasties"，"Tianjin Social Sciences" 2021 Issue 1)。

In short，Historians through their respective sorting and research，On the one hand, it is certain that there was no concept of "North bet365 best casino games" in ancient times，The modern meaning of "North bet365 best casino games" first appeared at the end of the 19th century；On the other hand, there are still different understandings of the time when the term "North bet365 best casino games" appeared。

　　The evolution of the concept of North bet365 best casino games

The evolution of the so-called North bet365 best casino games concept here，Refers to the "from vagueness to clarity" experienced after the emergence of the word "North bet365 best casino games" in the modern sense、The process of "from multiple meanings to one meaning"。The meaning of the title as a conceptual study of North bet365 best casino games，Historians have also discussed this。

As far as you can see，One of the earliest scholars who discussed the evolution of the concept of North bet365 best casino games since the 21st century is Yu Zixia、Song Enrong、Zhang Limin et al。Among them，Yu Zixia and Song Enrong were investigating education during the Japanese invasion of bet365 best casino games，A historical interpretation of "North bet365 best casino games" at that time，Emphasis on "North bet365 best casino games" as a special name，It was a gathering point in Sino-Japanese relations before the July 7th Incident，It is a regional concept formed due to Japan's implementation of the so-called "North bet365 best casino games Policy" and the solution of the so-called "North bet365 best casino games Issue" (Yu Zixia、Song Enrong: "The Complete History of Japanese Invasion of bet365 best casino games Education" Volume 2，People's Education Press 2005 Edition，Page 47)。After Zhang Limin verified the time when the word "North bet365 best casino games" appeared，Focus on the domestic and foreign political environment、The communication role of newspapers、Used in some fields closely related to the public、Four levels including the identification of administrative agencies and intellectual circles，Examined the evolution of the concept of North bet365 best casino games。He thinks，In the context of foreign forces gradually penetrating into our country and Chinese people paying attention to safeguarding sovereignty，The term "North bet365 best casino games" with a regional concept is passed through the media、Societies、Propagation through multiple channels including intellectual circles and the public，Given politics、Economy、Culture、Water Conservancy、Multiple connotations such as geography，And with the help of local administrative agencies，Become a well-known and widely used vocabulary with spatial concepts；The government establishes an administrative management mechanism named "North bet365 best casino games"，Played a vital role in North bet365 best casino games becoming a regional term。

Yao Yanchao also pointed out after re-examining the issue of when the term "North bet365 best casino games" appeared，Before 1931，The biggest influence on the use of the term "North bet365 best casino games" is various forms of sports games，Especially the North bet365 best casino games Games、National Games and Far Eastern Games，During the North bet365 best casino games Games，This is the period when newspapers use the word "North bet365 best casino games" most intensively。After 1931，The concept of "North bet365 best casino games" is quickly cooling down in the sports world，Instead, the word "North bet365 best casino games" is connected with Japanese invasion，Frequent、Concentrated in the headlines of major newspapers。In the process，The significance of "North bet365 best casino games" of the times is highlighted，"North bet365 best casino games" is widely spread。After the July 7th Incident in 1937，Resisting the enemy and saving the nation has become the unanimous will of the whole country，The meaning of "North bet365 best casino games" has declined，“Instead is the overall crisis of the Chinese nation”。

Zhong Weimin and Wang Zhenghua made further arguments based on the results of the above scholars，The understanding is reflected in three aspects。First, the use of the concept of "North bet365 best casino games" during the Republic of bet365 best casino games not only reflects the game between various forces，And it also makes the concept of "North bet365 best casino games" gradually clear，The current official concept of North bet365 best casino games (including Hebei)、Shanxi、Beijing、Tianjin、The area around Inner Mongolia) was formed very late (after Shandong was politically and geographically included in East bet365 best casino games in the 1940s)，And its political significance far exceeds other meanings。The second is during the formation and evolution of the concept of "North bet365 best casino games" during the Republic of bet365 best casino games，Shandong’s situation is the most unique，Originally belongs to North bet365 best casino games region，But after several adjustments to the plan，Eventually became part of East bet365 best casino games。Third, the historical research in the name of North bet365 best casino games is closely connected with the formation and evolution of the concept of "North bet365 best casino games"。

In short，Since entering the 21st century，Discussions on conceptual evolution have become an integral part of conceptual research in North bet365 best casino games。Historians discuss with different focuses，The evolution process is presented more clearly。

　　The spatial extent of North bet365 best casino games

The definition of spatial scope is another indispensable part of the concept of North bet365 best casino games，It is also an issue that attracts much attention from scholars。Since entering the 21st century，Historians mainly discuss from two levels: academic exploration and research practice。

At the level of academic exploration，After most scholars discuss the origin and evolution of the concept of North bet365 best casino games，Focus on defining the spatial scope of North bet365 best casino games。Among them，Luo Shuwei thinks，North bet365 best casino games refers to the north of the Yellow River、South of the Northeast Region，East of Guanzhong area，Yellow Sea、The area west of the Bohai Sea，Almost covers Hebei (Zhili)、Henan、Shandong、The four provinces of Shanxi and some areas in southern Inner Mongolia。Zhang Limin defined the North bet365 best casino games region as the two cities and three provinces of Beijing, Tianjin and Hebei, Shandong and Shanxi、Part of Henan Province and the central and western regions of Inner Mongolia (Zhang Limin: "On the Spatial Definition and Evolution of North bet365 best casino games"，"Tianjin Social Sciences" 2006 Issue 5)。Zhong Weimin and Wang Zhenghua think，Define the scope of "North bet365 best casino games" in the Ming and Qing Dynasties as Zhili、Shandong、Shanxi、Four provinces in Henan (including Beijing)，Relatively consistent with historical reality and academic recognition。

At the level of research and practice，Scholars mostly follow the concept that "history has no fixed rules"，The spatial range of areas divided according to different research objects。After the 1980s，Historians have basically accepted Schkenya’s definition of the spatial scope of North bet365 best casino games (from the perspective of administrative divisions，North bet365 best casino games includes Hebei、Shandong Province，Most areas of Henan Province and Jiangsu、Northern Anhui Province，Eastern Shanxi Province and part of Shaanxi Province)。Turn of the century，Yuan Shuyi、Qiao Zhiqiang and other scholars have also defined the spatial scope of North bet365 best casino games。The former was studying the economic and social development of North bet365 best casino games in modern times，Point out that North bet365 best casino games mainly includes Hebei (including Beijing and Tianjin), Shanxi, Shandong, Henan and Inner Mongolia in terms of geographical scope，Think that although "Hebei、Lu、Henan certainly occupies an important position in the entire North bet365 best casino games region，And has more geography、Commonalities in human factors”，But it does not cover the entire "community" type in North bet365 best casino games，Because they basically just represent the North bet365 best casino games Plain area，Shanxi and Inner Mongolia areas “belong to the other two community types respectively” (Yuan Shuyi、Ren Hengjun、Dong Conglin: "The Difficult Transition Process—Research on the Economic and Social Development of North bet365 best casino games in Modern Times"，People's Publishing House 1997 Edition，"Preface" page 3)。The latter was investigating social changes in rural North bet365 best casino games in modern times，It is believed that North bet365 best casino games includes the four provinces of Shanxi, Hebei (including Beijing and Tianjin), Henan and Shandong, and Inner Mongolia、Some adjacent areas in Shaanxi，"From a geographical perspective，Roughly what we usually call the middle and lower reaches of the Yellow River" (Editor-in-Chief Qiao Zhiqiang: "Social Changes in Rural North bet365 best casino games in Modern Times"，People's Publishing House 1998 Edition，Page 24)。"Urban Modernization in North bet365 best casino games in the 20th Century" published by Tianjin Academy of Social Sciences Press in 2002，Quite representative of the definition of the spatial scope of North bet365 best casino games by some scholars at that time。Among them，Some scholars regard the four provinces of Shanxi, Hebei, Shandong and Henan and Inner Mongolia as the spatial scope of modern North bet365 best casino games，Some scholars follow Schkenya’s definition of the spatial scope of North bet365 best casino games，There are also scholars who use Qingdao, Shandong or Linfen, Shanxi as research objects。After 2010，Fan Rusen was studying the economic geography of North bet365 best casino games in modern times，The spatial scope of North bet365 best casino games is generally limited to Shanxi under the administrative region of the Republic of bet365 best casino games、Hebei、Henan、Shandong、All or part of Jiangsu and other provinces (Fan Rushen: "Modern Economic Geography of bet365 best casino games" Volume 7 (Modern Economic Geography of North bet365 best casino games and the Mongolian Plateau)，East bet365 best casino games Normal University Press 2015 Edition，Page 4-5)。An Bao discusses the “absentee landlords” and the changes in rural society in North bet365 best casino games，Definition of modern North bet365 best casino games as the five provinces and two cities of Shanxi, Hebei, Shandong, Henan, Shaanxi and Beijing and Tianjin，“The geographical scope is roughly between 30° and 40° north latitude，North and Northeast、Connecting to Inner Mongolia，Qinling Mountains in the south、The Huaihe River is bounded by a line，To the east is the Yellow Sea and the Bohai Sea" (An Bao: "Leaving Home but Not Leaving the Land: Absent Landlords and Rural Changes in North bet365 best casino games in the Early Twentieth Century"，Shanxi People's Publishing House 2013 Edition，Page 32)。In recent years，Li Lifeng was investigating the Agrarian Revolution and the changes in rural power in North bet365 best casino games，Jiang Shandong、Hebei and other provinces as spatial scope (Li Lifeng: "Land Reform and Rural Power Change in North bet365 best casino games: An Examination of Political History"，Jiangsu People’s Publishing House 2018 Edition，Page 1)。Wang Xinghui is discussing the changes in the lives of children in the North bet365 best casino games base area，Shanxi、Hebei as the main spatial scope (Wang Xinghui: "Research on the Life Changes of Children in the North bet365 best casino games Base Area"，Jiangsu People's Publishing House 2022 Edition，Page 6-7)。

It can be seen from this，Due to different research orientations and research objects，Historians have different opinions on the spatial extent of North bet365 best casino games、Unable to agree on one thing。Anyway，Since the 21st century，Historical circles have made many new developments in the study of the concept of North bet365 best casino games，The origin of the concept of but in North bet365 best casino games、Far from consensus on issues such as evolution and spatial scoping，This provides room for further expansion of related research。
