The ancients divided China into nine regions, so-called "Kyushu". The map of mountains and rivers in Kyushu, Gong Yu drawn in the Atlas of the Emperor.

Extended data:
More than 4,000 years ago, the land of China was flooded and Yu was ordered to control water. He adopted the concept of "water control must be smooth, water must flow down, high places must be chiseled, and low places must be sparse" to dredge the river, let the flood pass quickly and finally lead it into the sea.
Dayu's water control is not a matter of one person, but also needs the support and cooperation of clans and tribal leaders along the way. As a result, Dayu of Xia tribe became the commander-in-chief of each tribe (alliance) to deal with the flood of this tribe.
After 13 years of treatment, all the floods finally flowed down the river and merged into the sea, and the rivers were smooth, initially forming "Kyushu" on the land of China. "Zhou", from the glyph point of view, is the shape of the river around the highlands and hills. Shuowen said, "Water can live in Yuezhou." It can be seen that the original intention has nothing to do with administrative divisions, but natural terrain.
Every "state" is a habitable land on the water. There are nine such continental plates, namely "Kyushu".
