Yánhé

Yanhe Youxi was a Tujia native chief's office on the Wu River in northeastern Guizhou. Under the Yuan it belonged to the Sizhou commission, within the domain of the Tian chiefs.

After the Ming abolished the Sizhou and Sinan commissions in 1413, Yanhe Youxi came under Sinan Prefecture. Its principal chiefs were hereditary members of the Zhang clan, with hereditary deputies from the Ran clan. The office was in practice influenced by neighboring Youyang, whose chiefdom was abolished in the Qing reforms of 1735.
