李昪
In 936, believing that Wu's regent Xu Zhigao was interested in seizing the Wu throne, Gao wrote him to encourage him to do so. Xu eventually did so, in 937, ending Wu and establishing Southern Tang, and thereafter changing his name to Li Bian, as Li was his original family name. Subsequently, Gao requested to establish a liaison office at Southern Tang's capital Jinling, and Li Bian agreed.
