The Xiongnu also practiced marriage alliances with Han dynasty officers and officials who defected to their side. The older sister of the Chanyu (the Xiongnu ruler) was married to the Xiongnu General Zhao Xin, the Marquis of Xi who was serving the Han dynasty. The daughter of the Chanyu was married to the Han Chinese General Li Ling after he surrendered and defected. Another Han Chinese General who defected to the Xiongnu was Li Guangli, general in the War of the Heavenly Horses, who also married a daughter of the Chanyu. The Han Chinese diplomat Su Wu married a Xiongnu woman given by Li Ling when he was arrested and taken captive. Han Chinese explorer Zhang Qian married a Xiongnu woman and had a child with her when he was taken captive by the Xiongnu.
