Yànshān
North of the Yan Mountains, ridges rise toward the Bashang plateau, where forests and grasslands meet. The upper Luan River flows through this northern country before turning south through the mountains. In 1681 the Qing court established the Mulan hunting grounds in the wider region, drawing on pastures presented by Mongol princes. Imperial hunting expeditions brought the court and its followers into the uplands beyond the Great Wall.
