The Nine Provinces
King Shun, who reigned after his father Yao, was so impressed by Yu's engineering work and diligence that he passed the throne to Yu instead of to his own son. Yu is said to have initially declined the throne, but was so popular with other local lords and chiefs that he agreed to become the new emperor, at the age of 53. He established a capital at Anyi (Chinese: 安邑) - the ruins of which are in modern Xia County, in southern Shanxi Province - and founded what would be called the Xia Dynasty, traditionally considered China's first dynasty.
Yu's flood control work is said to have made him intimately familiar with all regions of what was then Han Chinese territory. According to the Book of History, Yu divided the Chinese "world" into nine zhou or provinces. These were Jizhou (冀州), Yanzhou (兗州), Qingzhou (青州), Xuzhou (徐州), Yangzhou (揚州), Jingzhou (荊州), Yuzhou (豫州), Liangzhou (梁州) and Yongzhou (雍州).
According to the Rites of Zhou there was no Xuzhou or Liangzhou, instead there was Youzhou (幽州) and Bingzhou (并州), but according to the Erya there was no Qingzhou or Liangzhou, instead there was Youzhou (幽州) and Yingzhou (營州). Either way there were nine divisions. Once he had received bronze from these nine territories, he created ding vessels called the Nine Tripod Cauldrons. Yu then established his capital at Yang City (陽城). According to the Bamboo Annals, Yu killed one of the northern leaders, Fangfeng (防風) to reinforce his hold on the throne.
