Where is the origin of authentic iron stick yam?

Iron stick yam originated in wen county, Jiaozuo.

Wenxian county is located in the envelope zone upstream of the intersection of the Yellow River and the Qinhe River. The Yellow River, the mother river, originates from the Qinhe River in Taihang Mountain and nourishes this land surrounded by mountains on three sides and facing water on one side.

The land in the county is divided into sandy soil near the Yellow River and sandy clay near the Qinhe River, and its dividing line is roughly in the line of Jinchangdian-Grand Canal-Zhang Xiaonan-Xulv Village, belonging to the Qinhe clay in the north and the sandy soil of the Yellow River in the south. According to the experience of local yam growers, Qinhe clay is more suitable for planting yam.
