《资治通鉴·隋纪·隋纪八》
王世充自从在洛水之北被李密打败后，就坚守营垒不再出战，越王杨侗派遣使者去慰劳王世充，王世充既惭愧又恐惧，就向李密要求交战。
王世充自洛北之败，坚壁不出；越王侗遣使劳之，世充惭惧，请战于密。
Since being defeated by Li Mi in the north of the Luoshui River, Wang Shichong had been firmly holding out in his camp and not fighting, and the Yue King Yang Dong sent an envoy to comfort Wang Shichong, who felt both ashamed and afraid, and hence asked to fight with Li Mi.
