Xun chided Xie Jing, "The idea of civility before punishment has been long promulgated and espoused. Liu Yi is wrong when he distorted the teachings of ancient sages through his sly manipulation of words. You're serving in the Crown Prince's residence, so you should advocate the principles of benevolence and righteousness in order to promote moral virtues.

The rivers have dried up so we should make a hasty retreat." Lu Xun did not respond, and he instructed his men to plant turnips and peas, while he played weiqi and other games with his officers as though nothing had happened.
