Henan province is named because most of its history lies south of the Yellow River. In ancient times, the middle and lower reaches of the Yellow River were criss-crossed, with dense forests and numerous wild elephants. Henan is described as a place where people hold elephants, which is the origin of the hieroglyph "Yu" and the origin of Henan's abbreviation "Yu".
