🇨🇳 Tongguan County

Tongguan County is a county in the east of Shaanxi province, China, administered as part of the prefecture-level city of Weinan. It is named after the Tong Pass, a historical fortress located south of the confluence of the Wei and Yellow Rivers. It is the southeastern corner of the Ordos Loop, the point at which the Qin Mountains turn the Yellow River sharply eastward, forcing it into the North China Plain, and borders the provinces of Shanxi to the north and Henan to the east.
