Khan exiled him to the no-man's land in Beihai to herd sheep. 19 years later, Emperor Zhao of the Han Dynasty succeeded to the throne, and the fierce Han Dynasty reconciled and married. The envoys of the Han Dynasty came to Hungary to ask Su Wu to return to China. Khan refused, but he couldn't say it, so he lied that Su Wu was dead.
