The Han responded by sending troops against Minyue, but before they could get there, Zou Ying was killed by his brother Zou Yushan, who surrendered to the Han. The Han army was recalled. Zhao considered visiting the Han court in order to show his gratitude. His high ministers argued against it, reminding him that his father kept his distance from the Han and merely avoided a breach of etiquette to keep the peace. Zhao therefore pleaded illness and never went through with the trip. Zhao did actually fall ill several years later and died in 122 BC. He was succeeded by his son, Zhao Yingqi. After the Han dynasty aided Nanyue in fending off an invasion by Minyue, Zhao Mo sent his son Yingqi to the Han court, where he joined the emperor's guard (宿衛, "Sù wèi"). Zhao Yingqi married a Han Chinese woman from the Jiu (樛氏) family of Handan, who gave birth to his second son, Zhao Xing. Yingqi behaved without any scruples and committed murder on several occasions. When his father died in 122 BC, he refused to visit the Han emperor to ask for his leave due to fearing that he would be arrested and punished for his behavior. Yingqi died in 115 BC and was succeeded by his second son, Zhao Xing, rather than the eldest, Zhao Jiande. In 113 BC, Emperor Wu of Han sent Anguo Shaoji to summon Zhao Xing and the Queen Dowager Jiu to Chang'an for an audience with the emperor. The Queen Dowager Jiu, who was Han Chinese, was regarded as a foreigner by the Yue people, and it was widely rumored that she had an illicit relationship with Anguo Shaoji before she married Zhao Yingqi. When Anguo arrived, quite a number of people believed the two resumed their relationship. The Queen Dowager feared that there would be a revolt against her authority so she urged the king and his ministers to seek closer times to the Han. Xing agreed to and proposed that relations between Nanyue and the Han should be normalized with a triennial journey to the Han court as well as the removal of custom barriers along the border. The prime of Nanyue, minister Lü Jia, held military power and his family was more well connected than either the king or the Queen Dowager. According to the "Records of the Grand Historian" and "Đại Việt sử ký toàn thư", Lü Jia was chief of a Lạc Việt tribe, related to King Qin of Cangwu by marriage, and over 70 of his kinsmen served as officials in various parts of the Nanyue court.
