     The name Chin-ch'uan during the Han period was applied to a tribe of the southern Man. During the Ming period, a lama monk of the Chin-ch'uan Monastery named Hai-mai was invested as Monk of the Transformation with hereditary domain in the Chin-ch'uan region. Subsequently his descendants (evidently he was a marrying monk) multiplied and spread out to inhabit the drainage area of the Chin Ch'uan or Gold River. During the early Ch'ing period when feudatories were conferred by the Manchu rulers, this region was divided up into the Ta-chin-ch'uan or Great Gold River, and the Hsiao-chin-ch'uan or Little Gold River territories.
