Weiguo should have existed for 907 years. Weiguo is the longest-lived country in the Zhou Dynasty, and it is also the last country to perish among many vassal states. From the founding of People's Republic of China (PRC) to its complete downfall in 907, there were 4/kloc-0 monarchs. As for why there were differences between 907 and 836, this may be because it was only 836 years from the establishment of the Zhou Dynasty to the first 209 years, and 907 was unrealistic.

In fact, in 254 BC, Wei was conquered by Wei, and its territory became Wei's territory, but there were still some people in Wei. After Qin captured Puyang and other places in 24 1 BC, Wei was forced to move to the Wild King in 239 BC. At this time, Wei existed in name only. When Cape Wei Jun was abolished as Shu Ren in 209 BC, Wei was completely destroyed, that is to say, Wei still existed in the Qin Dynasty. So the actual existence of Weiguo is 907.

Wei, a vassal state of Zhou Dynasty in China, is a vassal state of Ji surname, and the jurisdiction of others is roughly the present northern Henan and southern Hebei. Duke Zhou put down the rebellion in the native land of Yin merchants and jointly used merchant politics to govern the country, which achieved great success. After entering the Eastern Zhou Dynasty, due to frequent civil strife, the dynasty weakened, thus defending the country, leaving only 5,000 adherents living in Cao with the support of Song and Zheng. With Qi Huangong's assistance, we can rebuild our country, survive and become a small country. After a hundred years of rest, the economy began to prosper.

In the late Spring and Autumn Period, there was another incident of father and son fighting for the country in Weiguo, and the national strength was further weakened. In the first 254 years, Wei was occupied by Wei and became a vassal of Wei. Before 24 1, Qin attacked Wei, and Wei became a vassal of Qin again. Finally, in 209 BC, the country was completely destroyed.
