The so-called preventive education is to educate people in advance to prevent ideological problems and behavioral deviations, or to guide and transform behavioral deviations in ideological problems. Preventive education includes two meanings: first, when bad thoughts and wrong behaviors just appear, we should take corresponding preventive measures in time to prevent them from spreading or nip in the bud, which is the so-called "preventive measures". Second, take effective preventive measures to avoid bad thoughts and wrong behaviors before they happen. This is the so-called "nip in the bud".

To prevent delay is to warn us to work hard on the details and not to take it lightly. Ancient Ceng Yun said: Don't do it because of the small good, and don't do it because of the small evil. We should grasp a degree, stop at the main point, stop at the appropriate, and grasp the discretion. Once it is over, it will make the accumulation of things in quantitative change reach a new starting point, which will lead to qualitative change and lead to the loss of the whole game. This is the philosophical truth embodied in "preventing micro-duration" and plays an important role in forming good behavior habits and values. In order to prevent delay, we should strengthen our correct self-awareness and find and correct our bad behavior in time. At the same time, we should have correct values, be able to correctly understand the essence of things and avoid wrong thoughts and behaviors.

Nip in the bud is also very important for us to form good behavior habits and values. To "prepare for a rainy day", we must have a correct attitude towards things, have a certain foresight, and know that the result of doing so will have a bad influence on ourselves, so as to urge ourselves to actively seek effective measures to stop the development of things.
