Ch’in Qin River, Chinese (Pinyin) Qin He, or (Wade-Giles romanization) Ch’in Ho, or (Pinyin) Qin He, river rising in the T’ai-yüeh Shan (mountains) of Shansi sheng (province), China. It river of north-central China. It rises in the Taiyue Mountains of Shanxi province, China and flows south through the plateau past Ch’in-yüan Qinyuan and near Yang-ch’engYangcheng, through the southwest spur of the T’ai-hang ShanTaihang Mountains, and onto the plain of northern Honan Henan province, where . There it swings southeastward to join the Huang Ho at Wu-chih.The Ch’in He (Yellow River) at Wuzhi. The river’s total length is about 300 miles (485 km).

The Qin River’s lower course has a very low gradient, so that the heavy large volume of silt load carried down from the plateau by the current has caused extensive flooding since ancient times. In 609, with the construction of the Yung-chi Canal after the Yongji Canal was built from the area of Wu-chih Wuzhi northeast across the North China Plain to the area of Pekingpresent-day Beijing, the waters of the Ch’in Qin were diverted into the canal. The canal, however, fell into disuse at the end of the 8th century. In 1951–52 the Jen-min Sheng-li (“People’s Victory”People’s Victory (Renmin Shengli) Canal was constructed, connecting Wu-chih Wuzhi with the Wei HoRiver, thus reopening the waterway of 609 and providing an outlet for floodwaters at the junction of the Ch’in Qin and the Huang Ho. The total length of the Ch’in River is about 150 miles (240 km).He.
