In order to "recuperate", Wendi tried to avoid fighting with South Vietnam. According to Zhao Tuo's request, he stopped guarding the border, built a ancestral grave for Zhao Tuo (now southeast of Zhengding, Hebei), and gave Zhao Tuo's younger brother an official position and a reward in his hometown. In this case, Lu Jia went to South Vietnam again, and Zhao Tuo promised to cancel the emperor and restore the relationship between vassal and vassal.
