Biên (Luy Lâu) in modern Hanoi and brought prosperity to the region, taking in many refugees from the north. His brothers Yi, Wei, and Wu administered the commanderies of Hepu, Jiuzhen, and Nanhai respectively. In 192, the southernmost district of Rinan Commandery, Xianglin, broke away and became the Kingdom of Lâm Ấp, otherwise known as Champa. Aside from this incident, Shi Xie's realm was relatively secluded from the state of endemic warfare and turmoil to the north. He provided support to the general Zhang Jin, situated in Cangwu and Yulin commanderies, in his conflicts with Liu Biao from 196 to 205, but stopped after the general's death.

Lü Dai reneged on his promise and beheaded them all, after which he abolished the two provinces, once again merging them together into Jiaozhou. After Shi Xie's death, the southern frontier continued to be viewed as an area of barbarians in the Han imagination. When Xue Zong visited the south in 231, he described the place in the following manner: Shi
