Pi

Pi was a Zhou dynasty (1045–256 BC) vassal state in ancient China. Also known as Xue, Pi was ruled by members of the Ren (任) family. Its progenitor Xi Zhong (奚仲), had been the Minister of Chariots (车正) for Yu the Great during the Xia Dynasty (~2070–1600 BCE) who was given land at the confluence of the Dan (丹水) and Yi Rivers (沂水) in the southern part of modern-day Shandong Province. During the Western Zhou Dynasty (1046–771 BCE), the State of Pi shares a border with the State of Song to the east and the State of Tan (郯国) to the north. History
