Minyue king was assassinated by his younger brother Yu Shan, who promptly surrendered. The Emperor sent court emissary Yan Zhu to the Nanyue capital to give an official report of Minyue's surrender to Zhao Mo, who had Yan return his gratitude to the Emperor along with a promise that Zhao would come visit the Imperial Court in Chang'an, and even sent his son Zhao Yingqi to return with Yan to the Chinese capital.
