Huang, so Tao Huang decided to have Xiu Yun kill him. In Jiuzhen, the Jin official, Li Zuo (李祚) continued to resist, but after a long battle, Tao Huang recaptured the commandery. Administration of Jiao After Jiao returned to Wu, Sun Hao further appointed Tao Huang as Commissioner with Extraordinary Powers, Chief Controller of Jiao, Governor of Jiao and General of the Front. During his time in Jiao, Tao Huang pacified the Rau and other local tribes in Wuping (武平), Jiude (九德), and Xinchang (新昌), turning them into new commanderies. When combined with Jiuzhen, the commanderies were made up with more then thirty counties. Tao Huang was also popular and beloved by the populace of Jiao. On one occasion, he was appointed as Commander of Wuchang and had to leave the province. The people of Jiao were devastated and insisted on having Tao Huang to stay, so he was reappointed as administrator of the region. In 279, Jin launched its conquest of Wu. Tao Huang was positioned far from the action and was fighting the rebel, Guo Ma, in Guangzhou at the time, so he did not participate in the defence. Jianye capitulated in 280 and Sun Hao formally surrendered to the Jin forces. Sun wrote a letter to Tao Huang's son, Tao Rong (陶融) to ask his father to surrender. Upon hearing the news, Tao Huang mourned his state for days before replying to give his surrender. Emperor Wu of Jin allowed him to keep his existing positions while granting him promotions. Service in the Jin Dynasty Shortly after Wu's demise, Emperor Wu intended to reduce the number of troops in each province and commandery across the state. Tao Huang personally wrote a letter to the emperor to exclude Jiaozhou from this policy. His reasoning were that Jiaozhou was too far from the capital in Luoyang, and the harsh terrains meant that a rebellion by the locals or officials would be hard to put down. He also pointed out the imminent threat of the independent commanderies around the area and his previous encounters with the Cham kingdom of Lâm Ấp, led by their king Phạm Hùng, and their ally, Funan. In the same letter, Tao Huang also requested that taxes in Jiao be paid with pearls, which were the local people's general source of income, and that merchants were to be allowed to trade in the region.
