The South River is often also called the West River (constituting, as it does, the main trade route) up to a point 30 miles above Nanning, where it is bifurcated into the Left Branch leading to Lungchow, and the Right Branch leading to Poseh, whence is a main trade route into Yunnan, by which the trade with Hongkong and Canton via Wuchow and via Pakhoi finds its way; Poseh is accessible to large native craft, of perhaps 30 tons capacity, navigated through the many rapids with great skill.
