窦建德
Li Shimin took Wang Shichong and Dou Jiande back to the Tang capital Chang'an to present them to his father Emperor Gaozu. When Emperor Gaozu met Wang and rebuked him, Wang stated, "I should be beheaded, but the Prince of Qin had agreed to spare me." In fall 621, Emperor Gaozu spared him but demoted him to commoner rank, exiling him and his clan to modern Sichuan, while executing Dou.
