Mencius - Book 1, Part 2, Chapter 11B

'Now the ruler of Yen was tyrannizing over his people, and your Majesty went and punished him. The people supposed that you were going to deliver them out of the water and the fire, and brought baskets of rice and vessels of congee, to meet your Majesty's host. But you have slain their fathers and elder brothers, and put their sons and younger brothers in confinement. You have pulled down the ancestral temple of the State, and are removing to Ch'î its precious vessels.

'How can such a course be deemed proper? The rest of the kingdom is indeed jealously afraid of the strength of Ch'î; and now, when with a doubled territory you do not put in practice a benevolent government; it is this which sets the arms of the kingdom in in motion.

'If your Majesty will make haste to issue an ordinance, restoring your captives, old and young, stopping the removal of the precious vessels, and saying that, after consulting with the people of Yen, you will appoint them a ruler, and withdraw from the country; in this way you may still be able to stop the threatened attack.'
