Xuzhou "sea, Dai, Huai, only Xuzhou". The Yellow Sea, Mount Tai and Huaihe River are equivalent to southern Shandong, northern Jiangsu and Anhui today. There are Mengshan (south of Mengyin County, Shandong Province) and Yushan (northeast of Tancheng County, Shandong Province). There are Huaishui and Yishui in Sichuan.

Yangzhou "Huai, Yang Wei Yangzhou". From the south of Huaihe River to Haidong, it is equivalent to today's Jiangsu, southern Anhui and eastern Jiangxi. There are Peng Li (now Poyang Lake) and Zhenze (now Taihu Lake).
