《水经注·卷一》
又按《穆天子传》，穆天子从昆山到周朝都城，是按照西方的里程计算的，从周朝都城漓水以西到河宗之邦、阳纤之山，计三千四百里；从阳纤以西到河首是四干里，共计七千四百里。
又案《穆天子传》：天子自昆山入于宗周，乃里西土之数。自宗周瀍水以西，至于河宗之邦、阳纤之山，三千有四百里，自阳纤西至河首四千里，合七千四百里。
According to the "Mu Tianzi Zhuan", Mu Tianzi traveled from Kunshan to the capital of the Zhou Dynasty according to the mileage calculation in the West. It is 3,400 miles from the west of Zhou Dynasty's capital, Lishui, to Hezong Kingdom and Yangxian Mountain. It is 4,400 miles from Yangxian in the west to Heshou, totaling 7,400 miles.
