"Don't do good deeds because they are small, and don't do evil because they are small." This sentence was what Liu Bei told his son Liu Chan before his death during the Three Kingdoms period. It was intended to educate Liu Chan not to despise small things. Don't not do good things because they have little impact, and don't do bad things because they have little impact. This sentence still has guiding significance for us to cultivate our moral character. Don't neglect a good deed because it is small. A mistake often starts from a small thing that has no starting point. As the saying goes, "You steal a needle when you are young, you steal gold when you are big." "A thousand-mile embankment breaks in an ant nest." This is the truth. Although bad things are small, they can corrode a person's soul. Over time, quantitative changes will lead to qualitative changes. , will eventually jump into the pit of crime and become a shameful sinner. Some students usually do not pay attention to their moral cultivation, and over time develop bad habits: being late, absent from class, hanging out in Internet cafes, whistling, beating and scolding each other, sarcasm, and even making friends with some social gangsters to blackmail their classmates for money; some even They went out to commit petty thefts; others gathered a group of people to fight because of some conflicts with their classmates. Students, don’t think this is a trivial matter. If we hear this, fail to realize the seriousness of the problem, do not gradually correct it, and continue to go our own way, the consequences will be disastrous, and it will develop into illegal behavior and eventually be punished by the law. sanctions. Some of the behaviors of some students are now illegal, such as carrying out robberies, stealing copper pipes for air-conditioning in family areas, etc. It is just because you are still young and have not been investigated criminally. Once you continue, you will be severely punished and destroyed. If your future is ruined, it will be too late to feel sad and regretful at that time. Don't let a good deed be too small. A drop of water can reflect the brilliance of the sun, and a good deed can reveal a person's noble and pure heart. Small things are the foundation of big things, and big things are the accumulation of small things. If you underestimate the ordinary and good things, you will not do great things. If you despise a drop of water, there will be no vast ocean. If you despise a tree, there will be no dense forest. If you despise bricks and tiles, you will not be able to build high-rise buildings. For thousands of years, the ancients have many famous aphorisms emphasizing the importance of "doing small things": gathering armpits makes fur, gathering sand makes a tower, building up soil makes a mountain, accepting rivers makes a sea, and accumulating good deeds makes a virtue. We must start from small things and start from scratch. It is not difficult for a person to do a good deed. What is difficult is to do good deeds all his life. If a person insists on doing good deeds and not doing bad things, then he will definitely get the respect of the society and the praise of the people. Turning off the lights, saying a kind word, giving up your seat, and smiling are all contributions to the interests of the public. Small acts of kindness, a little effort, do not require us to pay a lot, but they can exchange for understanding, harmony, and friendship. Do something for the society, do something for others, do something for yourself, and a beautiful life lies in everyone's every moment. Creation in drops, extending in perseverance.

Generally speaking: Those who benefit others are good, and those who benefit oneself are evil.

Liaofan’s four teachings say: If we put it in a more precise way, goodness has truth and falsehood; it has end and crookedness; it has yin and yang; it has right and wrong; Right; some are half, some are full; some are big, some are small; some are difficult, some are easy; all should be distinguished deeply. If you do good without exhausting principles, you will claim to practice it, but you will not realize that committing evil is a waste of effort and is useless.
