1. People know the world by their own perception and cognition, but they are bound by it. That's called reality. However, perception and cognition are ambiguous things. Reality may be just a mirage. People are living in their own self-awareness. Don't you think so?

2. In terms of nature and self-awareness, what others think of us is far from what we are in reality, so we can't be trusted.

3. Give up being what you can't be, and you can be yourself. We should learn to give up, stop dreaming and chasing in vain, know ourselves realistically, objectively and accurately, and find out who we are, what we want and what we can do. We should know how to stick to it, and persevere in the direction and goal that we have identified, so as to realize a perfect ideal and life.

4. It has been said that even lovers can't get to know a person for the rest of their lives. Their understanding of their lover is only based on the judgment of mutual cognition. No one can really understand each other's thoughts and feelings. It's just countless expressions and dictation to each other, or the self-cognition generated by putting similar experiences on themselves. They will always just stand on their own point of view to visualize each other's situation, so as to achieve similarity. So people are always lonely, even if couples live together, it is also a lonely break, from the beginning to the end.

5. I saw a passage: judging people by their appearances is absolutely scientific. Character is written on the lips, and happiness is exposed in the corners of the eyes. Rational sensibility is placed in the voice, and sincerity and hypocrisy are reflected in the pupil. Standing posture shows talent and tolerance, and gait shows self-cognition. There is a recent mood in the expression, and the past years are in the brow. Clothing shows aesthetics, and hairstyle shows personality. Career depends on hands, cultivation depends on feet. Poverty will radiate from the whole body.
