In 196 BC, Emperor Gaozu of Han dispatched Lu Jia to recognize Zhao Tuo as king of Nanyue. Lu gave Zhao a seal legitimizing him as king of Nanyue in return for his nominal submission to the Han. Zhao received him in the manner of the local people with his hair in a chignon while squatting. Lu accused him of going native and forgetting his true ancestry. Zhao excused himself by saying he had forgotten the northern customs after living in the south for so long.
