In 138 BC, Minyue attacked Dong'ou and besieged their capital. Dong'ou managed to send someone to appeal for help from the Han. Opinions at the Han court were mixed on whether or not to help Dong'ou. Grand commandant Tian Fen was of the opinion that the Yue constantly attacked each other and it was not in the Han's interest to interfere in their affairs. Palace counsellor Zhuang Zhu argued that to not aid Dong'ou would be to signal the end of the empire just like the Qin. A compromise was made to allow Zhuang Zhu to call up troops, but only from Kuaiji Commandery, and finally an army was transported by sea to Dong'ou. By the time the Han forces had arrived, Minyue had already withdrawn its troops. The king of Dong'ou no longer wished to live in Dong'ou, so he requested permission for the inhabitants of his state to move into Han territory. Permission was granted and he and all his people settled in the region between the Changjiang and Huai River.
