Duan Guang

Duan Guang, also called Duan Xinguang, was the ninth hereditary zongguan of Dali under the Mongol Yuan dynasty, succeeding in 1333. His general Gao Peng routed rebel tribal troops at Hewei Pass near Xiaguan in a battle so bloody the river was said to run red.

He fought the Mongol prince of Liang over their border and in 1343 defeated the prince's invading army at Kunmi Mountain, after which they divided the region at Luona Pass, the Duan ruling the south. He died in 1344 and was succeeded by his brother Duan Gong.
