侯景攻打广州，没有取得成功，他听说西魏的救兵将要赶到，就召集全体将领一道商议对策。兼管洛州事务的卢勇请求去前方观察形势，在征得侯景同意后，他便带领一百名骑兵来到大隗山，在这里，他们遇上了西魏的部队。
侯景攻广州，数旬，未拔，闻魏救兵将至，集诸将议之，行洛州事卢勇请进观形势。乃帅百骑至大隗山，遇魏师。
Hou Jing attacked Guangzhou but failed to capture it. When he heard that reinforcements from Western Wei were about to arrive, he summoned all his generals to discuss countermeasures. Lu Yong, who was in charge of affairs in Luozhou, asked to go to the front to observe the situation. After obtaining Hou Jing's consent, he led a hundred cavalrymen to Dawai Mountain, where they encountered the Western Wei forces.
