Let's start with a little thing. I believe that when we were young, we were all familiar with this scene: during class, the teacher was helping the students answer a question, and suddenly there was a mistake. Then a "schoolmaster" stood up and said, "Teacher, what you said is wrong", and then told the teacher where he was wrong in front of everyone. With that, he sat down by himself and left the teacher alone on the platform.
It is true that teachers don't care about this kind of thing, and students may even think that people who stand up and correct mistakes really learn, but everyone seems to have overlooked one thing. Once this kind of behavior becomes a habit of this student, I am afraid that he will do whatever he thinks is right, regardless of others' face.
But in this case, the correct way for a student with excellent moral quality should be to write down this mistake silently, talk to the teacher privately during the break, and then take the initiative to ask the teacher to correct this mistake in the next class. This will neither disturb the order nor embarrass the teacher.
Yes, this is a very small thing, but as one grows older, he will gradually find that those around him who don't know how to take care of others' faces have fallen into the abyss of perdition. I don't deny those who bravely stand up to protect the rights and interests of themselves and others, but being brave is not reckless. Courage also needs a way. If you can take care of all aspects of your thoughts while protecting your rights and interests, others will be happy to help you achieve your goals.
Society is a big dye vat, but one thing is the theorem that we live in society-when you are equal to others, respect is mutual. People with high cultivation know how to protect the dignity and face of others. They will never speak ill of others, let alone embarrass them.
