What do you mean, "Don't hang up until you see the devil"

"Don't hang your rope until you see the devil" is a folk proverb from War of Resistance against Japanese Aggression's time. It literally means that if you don't see the Japanese army (the devil), you don't have to hang the fuse of the mine. This is because a mine is usually a trip mine, and only when the lead wire is suspended and tightened will it cause an explosion, so as to avoid accidentally injuring one's own people.

Now, the phrase "don't let go before you see the devil" also means that when you are doing something, if you are not sure, don't rush to act first. Wait until the right time or conditions are ripe before taking action. This practice is similar to the principle of military preparation, and it is necessary to wait for the best opportunity to launch an attack.

This proverb means that when faced with various affairs or problems, don't act too impulsively or rashly, but wait for the right opportunity and conditions to ensure the effectiveness and success of the action.
