Southern Han
In October 930, Southern Han, a Chinese state in southern China during the Five Dynasties and Ten Kingdoms period, launched an attack on the Jinghai circuit, which at the time was a Vietnamese principality controlled by the Viet Khuc clan. The leader of the Khuc, Khuc Thua My, was taken prisoner by the Southern Han Emperor Liu Yan. In 931, the local strong Dương Đình Nghệ with an army of 3,000 had drove the Southern Han back to the borders.
