Jia ensured that Zhao Jiande, Zhao Yingqi's eldest son by his native Yue wife, took the throne, and quickly sent messengers to spread the news to the feudal rulers and officials of various areas of Nanyue. War and the decline of Nanyue The 2,000 men led by Han Qianqiu began attacking towns along the Han-Nanyue border, and the Yue residents ceased resisting them, instead giving them supplies and safe passage. The group of men advanced quickly through Nanyue territory and were only 40 li from Panyu when they were ambushed by a regiment of Nanyue soldiers and completely annihilated. Lü Jia then took the imperial tokens of the Han emissaries and placed them in a ceremonial wooden box, then attached to it a fake letter of apology and installed it on the border of Han and Nanyue, along with military reinforcements.
