Emperor Wu of Han
The Congs are originally of Xiongnu origin. They trace their ancestry to King Xiutu of the Xiongnu. In 121 BC, Xiongnu King Hunxie killed King Xiutu when Xiutu refused to surrender to the Chinese with Hunxie. The fourteen-year-old Crown Prince Midi was taken to China and raised as a stable hand. One day, when Emperor Wu of Han was inspecting the horses with his wives, all the servants were mesmerized by the royal entourage, except for Midi. Emperor Wu of Han took favor of the prince and granted him the Chinese surname Jin, meaning gold, because the prince used to make sacrifices with golden statues as a part of the Xiongnu rituals.
