After the establishment of the Western Zhou Dynasty, in order to stabilize the political power, the strategy of "feudal statehood and feudal statehood and feudal Zhou" was adopted, and the feudal princes were divided on a large scale, achieving the goal of "consolidating the Zhou Dynasty". According to modern scholars, according to historical documents and records of Jin Wen (bronze inscriptions), there were more than 170 countries and tribes in the Western Zhou Dynasty, some of which were not supplemented until archaeological discoveries, such as the "Zeng Kingdom" and the newly discovered "Yi Kingdom".
In recent years, Ningxia archaeology has made a major discovery, discovering a batch of oracle bone inscriptions, revealing a Western Zhou vassal state that was not recorded in historical books. At the site of Yaoheyuan in Guyuan City, Ningxia, scholars found an oracle bone inscription of more than 150 characters, which recorded a vassal state of the Western Zhou Dynasty named "Gain". This discovery fills in a gap in history and provides clues to our better understanding of the defenses of the Western Zhou capital.
The oracle bone inscription at the Yaoheyuan site mentions the words "Hou Bu Yu Wang" and "Hou Bu Yu Queen Mother", indicating that "Hou Bu Yu Wang" is a Western Zhou vassal state that has not been recorded in the official history. There are also oracle bone inscriptions showing that "Hou Bu Yu Rong" and "Hou Bu Yu Tang" and other contents indicate that there is a mutual attack and continuous war between the Hou Guo and the Rong people. This discovery not only explains the defensive layout of the Guyuan region during the Western Zhou Dynasty, but also reaffirms the credibility of Chinese historical books.
Although there is no record of the acquisition of the kingdom in the history books, this discovery confirms many records in the history books. The site of Yaoheyuan, after three periods of the late Shang, Western Zhou and Eastern Zhou dynasties, especially in the Western Zhou Dynasty, became "the site of the feudal capital of the early Western Zhou Dynasty". This also means that the Guyuan area was the military outpost of the Zhou Dynasty in the northwesternmost region and an important military fortress of the Zhou people.
Overall, although the Acquisition Kingdom is forgotten in the history books, its existence has been reconfirmed by archaeological discoveries. The oracle bone inscriptions at the Yaoheyuan site not only prove the credibility of the historical books, but also reveal the military importance of the kingdom in the Western Zhou Dynasty. The question of the status of the monarch and how it came to an end may require further research and research.
