A stretch of water
South of old Xiguan the Pearl River splits into its front and rear channels; Baietan is the broad, deep water at the fork. Qu Dajun's Guangdong Xinyu records "two li up the Pearl River lies Baietan, wide and deep". The "pool" is a deep channel where visiting merchant ships anchored from the Song dynasty onward. A water name, with no administrative boundary.
