《资治通鉴·隋纪·隋纪一》
贺若弼又请求让沿江防守的兵士每当轮换交接的时候，都一定要聚集广陵，于是隋军大举旗帜，营幕遍野，陈朝以为是隋朝大军来到，于是急忙调集军队加强戒备，随后知道是隋朝士卒换防交接，就将已聚集的军队解散；后来陈朝对此已习以为常，就不再加强戒备。
弼又请缘江防人每交代之际，必集广陵，于是大列旗帜，营幕被野，陈人以为隋兵大至，急发兵为备，既知防人交代，其众复散；后以为常，不复设备。
Heruo Bi requested that soldiers defending along the river gather at Guangling every time they rotated. As a result, Sui troops raised their banners on a large scale and set up camps in the open fields. The Chen Dynasty believed that it was the Sui army that had arrived. Hence, they quickly gathered troops to strengthen the defenses, but later came to the realization that it was just a routine troop rotation and dispersed the gathered troops. Over time, the Chen Dynasty was so accustomed to this that it stopped tightening its defenses.
