Huāyuántóu
Huayuantou was a fortified pass in the mountains northwest of Xixia, in the Nanyang region of Henan, guarding a passage through the ridges. The Qing Veritable Gazetteer of the Empire (Da Qing Yitong Zhi) counted it among the passes of Nanyang prefecture, and the Huayuanguan stream flowed through the valley below.
