Weken

The Weken were Jurchen clans of the Woken River basin, a tributary joining the Songhua at Yilan. In 1337 they lived under Yuan overlordship.

In 1408 the Ming established the Ouhanhe Guard in the Woken basin east of Yilan. Its chiefs received hereditary guard titles, and the region's Jurchens sent tribute to Beijing through the Nurgan system.
