周世宗
Throughout the winter of 957 Later Zhou forces captured a number of Southern Tang cities as they marched southwards, even gaining a direct land connection to their Wuyue vassal. In April 958 Li Jing sent out envoys again seeking peace with Chai Rong. The Southern Tang offered to cede all territory north of the Yangtze to the Later Zhou and become a vassal. These terms were acceptable to Chai Rong. The state once called Great Tang (大唐) was rebranded the less grandiose Jiangnan (江南). Li Jing renounced the title of emperor and assumed the title of King of Jiangnan. The Later Zhou calendar and reign title were additionally adopted by the court of Jiangnan. The Later Zhou gained control over almost a quarter million families.
