In fact, the division of Kyushu is a huge nine-square grid. On the territory of China, two lines are drawn horizontally and two lines vertically to form a tic-tac-toe, which is just divided into nine parts, called Kyushu, with the emperor in the middle and paying tribute in all directions. 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. The records of the Three Emperors and Five Emperors are different in each period and in different ancient books, so is Kyushu, and the scope division in different periods is also different.
Kyushu was later called twelve states because Bingzhou, Youzhou and Yingzhou, which were separated from Jizhou, became twelve states together with the original Kyushu. At first, Kyushu was just a general statement, because the country is a very small geographical scope, and the vast land is divided into Kyushu, which is not exactly what it refers to, but gradually divided into specific parts. Kyushu is divided into nine administrative regions, which may have appeared in the Warring States period according to records.
There are mainly three divisions, and their regions are different. One division is Yuzhou, belonging to the Central Plains, in the lower reaches of the Yellow River, Henan, Shandong and other places. Xuzhou, starting from the Yellow Sea, Mount Tai and Huaihe River, also involves Shandong, Jiangsu, Anhui and other places. Jizhou originated in Hukou of the Yellow River, Yanzhou in the lower reaches of the Yellow River, Qingzhou in the Bohai Sea, involving Hebei and Shandong peninsulas, Yangzhou in the Huaihe River, Jingzhou in Jingshan, Liangzhou in Huashan and Yongzhou in Heishui and Xihe.
The second division is Jizhou and Yuzhou, which belong to most of Henan Province. The third division is Yuzhou, the primary position of Kyushu, starting from Henan. As the representative of Qingzhou Oriental, Mount Tai in Dongyue is the first of the five mountains.
