Ngọc Ma

Ngọc Ma lay in the mountain country west of Nghệ An and east of the Lao heartland. Its valleys were home to local rulers who negotiated with the growing power of Đại Việt. Vietnamese chronicles recall a chief named Quý, who had assisted Lê Lợi during his uprising and received high office in return. The forested highlands around the district were crossed by routes between the Mekong basin and the Vietnamese coast.
