《资治通鉴·周纪·周纪三》
攻占一个国家而天下人不以为秦国残暴，得到全天下的利益世人也不认为秦国贪婪，这样我国一举即可得到威名又能收获实际的利益。
拔一国而天下不以为暴，利尽西海而天下不以为贪，是我一举而名实附也，而又有禁暴止乱之名。
If we were to conquer a state, the people of the world would not think Qin was being cruel, and if we were to seize its wealth, the people of the world would not think Qin was being greedy. In this way, our state can not only gain prestige, but also substantial benefits.
