Rúxī

Rúxī was a fortified settlement west of Qīnzhōu, among the frontier communities near Đại Việt. A stockade of this name was recorded under the Song, and the Ming later maintained a patrol office in the district. In 1427 leaders of several frontier communities gave their allegiance to the Lê rulers of Đại Việt. Following negotiations with the Mạc court, the disputed districts were returned to Ming administration in 1540; several were then incorporated into Rúxī and neighbouring Tiēlàng.
