《资治通鉴·陈纪·陈纪六》
不如解除紧急状态保持友好关系，使对方松懈而没有准备，然后寻找机会，出其不意，就能一举而取。 
不如解严继好，使彼懈而无备，然后乘间，出其不意，一举可取也。 
“It is better to relieve the state of emergency and maintain amicable relations, waiting for the enemy to become more lax and unprepared, and then search for opportunities to attack by surprise, to capture them in one move.”
