The pronoun "Kyushu" comes from the ancient book Gong Yu. It is said that when Dayu was in charge of water conservancy in ancient times, the world was divided into Kyushu. Since then, Kyushu has become synonymous with ancient China. "Shan Hai Jing Hai Nei Jing" also records that "Yu Yun was the first to cover the soil and set up Kyushu."
On the issue of "Kyushu", Mr. Gu Jiegang's article "The Evolution of Country and Yue" can be said to be very detailed. If you are interested in the topic of wuyue in Kyushu, I suggest you read this article by Mr. Gu, and you will certainly gain something.
Mr. Gu pointed out:
"In the Spring and Autumn Period, Kyushu said that we did not deny it. But we dare say that people only had this illusory concept at that time, and there was no specific status and name of the nine countries. The specific status and name of the nine countries is the construction of people during the Warring States period. "
He also correctly explained the name "Kyushu".
He said, "The Three Nine Chapters of Shu and Shi Xue said that the' three' and' nine' mentioned by the ancients are imaginary numbers. If the' three' cannot be exhausted, then' nine' is a festival.
For example, according to the historian's record that "if it is a drop in the ocean" and "the intestines return nine times a day", Sun Tzu's record that "the good defender hides under nine places and the good attacker moves above nine days" only says that there are many, not necessarily nine places.
I think, maybe at the beginning of Kyushu theory. As long as they say there are many in the local area, they don't know how much to say, so they use the imaginary number' nine' as a representative. "
Mr. Gu Jiegang listed Kyushu's theories in Shangshu, Yizhoushu Occupational Prescription, Er Ya Shi Di, Lv's Spring and Autumn Tour and Shuo Yuan Bian Wu, and made a comparative study, finding that there are differences in the specific positions of names and theories in various countries. It can be seen that Kyushu was not a specific concept at that time, but a general region.
During the Warring States Period, nine countries were identified. At that time, the understanding of the region was more and more unified under the concept of "great unification", and the general framework of "Kyushu" was similar, but there were still different views on the names and geographical locations of some States, because everyone was building according to their own ideas and understanding and refused to communicate and coordinate with each other, so naturally there would be differences.
Therefore, the Nine Kingdoms only reflected people's geographical concepts and understandings during the Warring States period, which had nothing to do with ancient geography, and had nothing to do with Dayu's flood control. So, which Kyushu do you think?
