Zhao Xing and Zhao Jiande

Zhao Xing succeeded his father as king, and his mother became Queen Dowager. In 113 BC, Emperor Wu of Han sent senior minister Anguo Shaoji to Nanyue summon Zhao Xing and his mother to Chang'an for an audience with the Emperor, as well as two other officials with soldiers to await a response at Guiyang. At the time, Zhao Xing was still young and the Queen Dowager was a recent immigrant to Nanyue, so final authority in matters of state rested in the hands of Prime Minister Lü Jia. Before the Queen Dowager married Zhao Yingqi, it was widely rumored that she had had an affair with Anguo Shaoji, and they were said to have renewed it when he was sent to Nanyue, which caused the Nanyue citizens to lose confidence in her rule.

Fearful of losing her position of authority, Queen Dowager Jiu persuaded Zhao Xing and his ministers to fully submit to Han dynasty rule. At the same time, she dispatched a memorial to Emperor Wu requesting that they might join Han China, that they might have an audience with the Emperor every third year, and that the borders between Han China and Nanyue might be dissolved. The Emperor granted her requests and sent Imperial seals to the Prime Minister and other senior officials, symbolizing that the Han court expected to directly control the appointments of senior officials. He also abolished the penal tattooing and nose-removal criminal punishments that were practiced among the Yue and instituted Han legal statutes. Emissaries that had been sent to Nanyue were instructed to remain there to ensure the stability of Han control. Upon receiving their Imperial decrees, King Zhao and the Queen Dowager began planning to leave for Chang'an.

Prime Minister Lü Jia was much older than most officials and had served since the reign of Zhao Xing's grandfather Zhao Mo. His family was the preeminent Yue family in Nanyue and was thoroughly intermarried with the Zhao royal family. He vehemently opposed Nanyue's submission to the Han dynasty and criticized Zhao Xing on numerous occasions, though his outcries were ignored. Lü decided to begin planning a coup and feigned illness to avoid meeting the emissaries of the Han court. The emissaries were well aware of Lü's influence in the kingdom – it easily rivalled that of the king – but were never able to remove him. Sima Qian recorded a story that the Queen Dowager and the Zhao Xing invited Lü to a banquet with several Han emissaries where they hoped to find a chance to kill Lü: during the banquet, the Queen Dowager mentioned that Prime Minister Lu was against Nanyue submitting to the Han dynasty, with the hope that the Han emissaries would become enraged and kill Lü. However, Lü's younger brother had surrounded the palace with armed guards, and the Han emissaries, led by Anguo Shaoji, didn't dare attack Lü. Sensing the danger of the moment, Lü excused himself and stood to leave the palace. The Queen Dowager herself became furious and tried to grab a spear with which to kill the Prime Minister personally, but she was stopped by her son, the king. Lü Jia instructed his brother's armed men to surround his compound and stand guard and feigned illness, refusing to meet with King Zhao or any Han emissaries. At the same time, be began seriously plotting the upcoming coup with other officials.

When news of the situation reached Emperor Wu, he dispatched a man named Han Qianqiu with 2,000 officials to Nanyue to wrest control from Lü Jia. In 112 BC, the men crossed into Nanyue territory, and Lü Jia finally executed his plan. He and those loyal to him appealed to the citizens that Zhao Xing was but a youth, Queen Dowager Jiu a foreigner who was plotting with the Han emissaries with the intent to turn the country over to Han China, giving over all of Nanyue's treasures to the Han Emperor and selling Yue citizens to the Imperial court as slaves with no thought for the welfare of the Yue people themselves. With the people's support, Lü Jia and his younger brother led a large group of men into the king's palace, killing Zhao Xing, Queen Dowager Jiu, and all the Han emissaries in the capital.

After the assassinations of Zhao Xing, the Queen Dowager, and the Han emissaries, Lü 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.
