李勣
He therefore sent Guo to Chang'an to report to Li Mi. Emperor Gaozu of Tang heard that Xu had sent messengers, but with no petitions to submit to Tang, only reports for Li Mi, and was surprised. He summoned Guo and questioned him, and Guo relayed what Xu's intents were. Emperor Gaozu was impressed and stated, "Xu Shiji remembers his lord and surrenders his accomplishments, and is really a pure-hearted subject." He thus bestowed the imperial clan name of Li (which he shared with Li Mi) on Xu, who thereafter would be known as Li Shiji. He also created Li Shiji the Duke of Cao and his father Xu Gai (thereafter known as Li Gai as well) the Prince of Jiyin, although Li Gai declined the honor and was subsequently created the Duke of Shu. Li Shiji remained in charge of the Liyang region to resist against Wang and Dou Jiande.
