Lóngjǐng

Longjing lies in the valley of the Hailan River, north of the Tumen. The Hailan, whose name means elm in Manchu, flows through the hills before joining the Burhatun and the Tumen river system. The river gave its name to an administrative district under the Jurchen Jin. During the Qing, the Hailan was among the rivers reserved for the collection of freshwater pearls, while the surrounding forests and mountains supplied other products for the imperial court.
