Rùnyán

Rùnyán lay in the salt-producing highlands of southwestern Sichuan. The Yuan established a salt-well command here in 1277, later making it a county under Baixing. In 1393 the Ming set up the Yánjǐng military garrison. Salt from the White and Black wells of the Yanyuan area travelled along routes through mountain communities towards Ninglang and Lijiang.
