The historical events and geographical locations described in this article are fictitious and should not be considered fact. But this text presents us with a hypothetical historical situation involving the Xinjiang region of China and a place called the Tangnu Wulianghai. Although no such region has existed in actual history, the complex international relations and geopolitical situations described in this article reflect some of the tensions and conflicts that do exist throughout history.
In the 19th and early 20th centuries, the Xinjiang region was indeed a battleground for great powers, especially during the "big game", when Britain and Russia fought for influence in Central Asia. At the same time, China during this period did face the threat of civil strife and foreign aggression, leading to the loss of territory and sovereignty.
In addition, although the article mentions a "Dawei" who left China in 1994, this does not correspond to historical records. In fact, no ethnic group called the "Dawei" became independent from China in 1994.
As for the situation in the Tangnu Ulyanghai region, although there is no such area in history, it can be seen from the description that it played the role of a border region in the text, going through the ruling changes of several dynasties until it finally became part of Russia. This type of story reflects the complex political and ethnic relations of the border regions and the importance of these regions in the politics of great powers.
Overall, while the story is fictional, it shows the author's attempt to explore complex issues of international relations and national identity through a hypothetical historical situation. While it does not represent real historical events, it nevertheless offers important reflections on geopolitical complexity and national self-determination.
