Qīngchuān
Qingchuan lies in the mountains northwest of Guangyuan, where the old Yinping road crossed from the highlands into Sichuan. In 263 the Wei general Deng Ai led his army over this difficult route in the campaign against Shu. Steep mountains and deep valleys forced the troops to cut paths and make bridges. The surviving traces of the road near Qingxi recall the formidable journey through this wooded country.
