Xunzi: The first is prevention, the second is rescue, and the third is caution. To prevent something before it happens, to stop it before it happens, is to save it, to do it before taking responsibility is called warning, which is translated into modern

Xun Yue, a political commentator and historian during the Eastern Han Dynasty, has a passage in "Shen Jian·Miscellaneous Words": "There are three techniques for advancing loyalty: one is defense; the other is rescue; the third is warning. Prevent it from happening before it happens. It's called prevention, it's called prevention, it's called prevention, it's called prevention, it's called prevention, it's called prevention, it's called prevention, it's called prevention, it's called warning. The next best thing is to stop something bad when it first happens; the next best thing is to punish something bad after it happens. This passage theoretically explains that control after the event is inferior to control during the event, and control during the event is inferior to control before the event.

"Prevention is the best." Everything will be successful if it is foreseen, and it will be ruined if it is not prepared. Prevention means actively seizing the initiative to promote the development of things.

The key to prevention is to pay attention to details, prevent minor changes, do the work in advance, treat the disease before it occurs, and eliminate the trouble before it arises.

"Save the next best thing." When conflicts and disputes first arise, timely measures should be taken to remedy them so that they can be stopped before they occur.

"Precepts are the next thing". "Discipline" means to strengthen punishment and learn lessons after conflicts and disputes occur. It is a last resort, but it is not too late to remedy the situation.

Although "do it and take responsibility for it" is a bad policy, it also means prevention.
