There is no such person in history. The original biography of Chu Qiao is a novel with an overhead history. The male name is Zhuge Yue, and the TV series was changed to Yu by applying the history of the Western Wei Dynasty. Yu Wentai really came to power in the Western Wei Dynasty, and the emperor was only Yu Wentai's puppet, while Yu Wentai did not claim to be the emperor. After Yu Wentai's death, his nephew set up his son Yu Wenjue to usurp the throne, established the Northern Zhou Dynasty, and the Western Wei Dynasty perished.
