《战国策·燕三·燕太子丹质于秦亡归》
我私下考虑能得到天下最勇敢的人出使秦国，用重利引诱秦王，秦王贪图这些厚礼，我们就一定能如愿以偿了。
丹之私计，愚以为诚得天下之勇士，使于秦，窥以重利，秦王贪其贽，必得所愿矣。
I have been thinking privately that if I can find the bravest man in the world, send him to Qin, and tempt King of Qin with great rewards, King of Qin will certainly be greedy for the generous gifts, and we will certainly achieve our goal.
