or HOANG-HO, a large river of the Chinese empire, rises in the Kuen Lun Mountains, not far from the Yang-tse-kiang, in the Koko Nor country. It flows at first N.E., across the Chinese province of Kansu, and enters Mongolia, in which country it continues its N.E. course, till past 41° N. Lat. It then re-enters China, and bends to the S., in which direction it flows for a long distance. About 35° N. Lat. it takes an abrupt turn, and for the remainder of its course flows eastward, falling into the Yellow Sea about 150 miles N. of the Yang-tse-kiang. Most of its affluents are of small size; the chief of them being, from the left, the Huang-tshu and the Fen-ho, and from the right the Wei-ho and the Hoey-ho. Its whole length is estimated at not less than 2000 miles, and it drains an area of more than 700,000 square miles.
