Поздняя Чжоу
The war between Later Zhou and Southern Tang eventually resulted in Southern Tang capitulation after heavy losses — with Southern Tang agreeing to submit as a vassal and cede all remaining territory north of the Yangtze River to Later Zhou. There were subsequent frequent exchanges of emissaries between Later Zhou and Southern Tang. On at least one occasion, Han served as Southern Tang's emissary to Later Zhou, at which time he had the chance to meet the Later Zhou general Zhao Kuangyin. Upon his return, Li Jing asked him about his impressions of the various Later Zhou generals. Han responded, "Overseer Zhao has an unusual appearance. It was difficult to judge him." When, after Guo Rong's death in 959, Zhao seized the throne from Guo Rong's son and successor Guo Zongsun in 960, establishing Song Dynasty as its Emperor Taizu, the people who heard Han's assessment were thus impressed.
