《资治通鉴·魏纪·魏纪四》
刘晔出来后，责怪杨暨说： 渔夫钓到一条大鱼，就要放长线跟在后，必须到可以制用时再用线将它牵回，那就没有得不到的。
晔见出，责暨曰： 夫钓者中大鱼，则纵而随之，须可制而后牵，则无不得也。
Liu Ye walked out and accused Yang Ji of the following: When a fisherman catches a big fish, he’d let out his line and follow behind. Only when it’s safe to reel it in will he pull the line, and thus it will not get away.
