Model of a rigged traging junk. Junks of this type traded from the port of Antung, near the mouth of the Yalu River in Southern Manchuria. They differed from the junks of Southern China in hull form and their sober decoration. Built with a flat bottom and without a keel, the hull of the junk was of extremely strong construction. A very large rudder was fitted, which in the absence of a keel provided some hold in the water.
