Following the collapse of the Qin dynasty, Zhao Tuo, a general of the Qin dynasty, took advantage of the Qin’s decline and the South region's crumbling political structure to set up his own kingdom, Nanyue. Nanyue was centered on Panyu (modern-day Guangzhou) and stretched from present-day Vietnam to modern-day Hunan. Despite coming from the North, Zhao Tuo assimilated into the Yue culture and created a new identity as the King of Nanyue. Zhao Tuo identified himself as Yue, married a Yue woman, incorporated locals into his army and even fought off Han invasions later on to protect his kingdom. He was able to successfully pull away from his past and make a name for himself in Vietnamese history. Some historians do not see him as a foreign conqueror, but as the defender of Vietnam against the Han Chinese, the legitimacy of the Triệu dynasty would be the source of debate and controversies among Vietnamese historians. Nevertheless, Zhaotuo sought to extend his territory further south to the Red River Delta region.
