Jinan County was built in the early Han Dynasty, which means "South of Water" and is a geographical place name. Jishui, commonly known as Daqing River, originated in Jiyuan City, Henan Province, and its basin is roughly equivalent to the Shandong section of the Yellow River. Later, due to the diversion of the Yellow River, it seized the riverbed and became the main channel of the lower reaches of the Yellow River. And Jiyuan, Jinan, Jiyang, Jining and other place names have been preserved, hence the name Jinan.
2 100 years ago, the Han Dynasty changed its name to Jinan (Historical Records). Jinan was founded in BC 164. BC 154, the country was abandoned and the county was changed.
