There is much dispute about the route taken by Men Haoran, a great poet of the Tang Dynasty,to Mount Tantai. This paper holds that Men Haoran made a boat journey from the north or northwest by west after departing the capital Luoyang for Yue,the Eastern Zhijiang, and that the Exi river was not the one in Kuozhou but was in Taizhou,somewhere near the route to Mount Tantai. So Men Haoran reached Mount Tantai by travelling along the route of Shanxi and Mount Tanlao after he got to Shanzhong in Yue.
