Xiao Tong
In 522, Emperor Wu's nephew Xiao Zhengde—whom he had previously adopted but then unadopted when Xiao Tong was born—resentful that he was not created crown prince, fled to Northern Wei, claiming to be the deposed crown prince and requesting Northern Wei aid. However, Northern Wei did not take his claim seriously, and in 523 Xiao Zhengde fled back to Liang. Instead of punishing Xiao Zhengde, however, Emperor Wu merely rebuked him tearfully, and in fact restored him to his title of Marquess of Xifeng.
