《贞观政要·卷九·论征伐》
自古以来，把它当做鱼鳖来畜养，应该对它缓简略些，如果一定要灭绝这一族类，我非常担心，它会像野兽被逼得无路可走时那样拼死反扑。
古来以鱼鳖畜之，宜从阔略。必欲绝其种类，深恐兽穷则搏。
Since ancient times, we have treated them like fish and turtles in a pond, we ought to be lenient with them, if we insist on wiping out this ethnic group, I am very worried that they will fight back with death-defying effort like an animal that has been driven into a corner.
