《陈书·本纪·卷一》
诸位将领都没有主意，王僧辩派杜则向高祖询问计策，高祖说： 从前柳仲礼几十万兵众隔水驻守，韦粲在青溪，竟然不渡河上岸，敌军登高了望，内外情势都看全了，就肆意行凶，使我朝廷军队全军覆没。
诸将未有所决，僧辩遣杜崱问计于高祖，高祖曰： 前柳仲礼数十万兵隔水而坐，韦粲之在青溪，竟不渡岸，贼乃登高望之，表里俱尽，肆其凶虐，覆我王师。
None of the generals had any ideas. Wang Sengbian sent Du Ze to ask Gao Zu what to do. Gao Zu said: “Previously Liu Zhongli had hundreds of troops stationed on the other side of the water. Wei Can was in Qingshui and he actually didn’t cross the river and land because the enemy had gone up to a high place to see everything that was going on inside and outside, and so they committed the crime of causing our troops to be entirely wiped out.”
