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.
