Xuxuan
Xuxuan , formerly romanized as Hsü-hsüan, was a legendary figure of Chinese history.
In the Records of the Grand Historian, Sima Qian's account of the origin of the House of Ying omits Xuxuan, simply stating that Zhongyan's great-great-grandson was Zhongjue. However, he later relates the speech of one of the marquesses of Shen, who states that "Xuxuan of the Rong" (, , Róng Xūxuān) was married to the daughter of one of his ancestors. This daughter of Shen was born at Mount Li (, , Lìshān) and gave birth to Zhongjue. He says this was the cause of peace between the Zhou and the Rong, as well as the reason for the allegiance of Zhongjue to the Zhou kings.
