The golden sentences of "The Three-Body Problem" are:

1. Memory is a river that has dried up long ago, leaving only scattered gravels in the lifeless river bed.

2. Emptiness is not nothingness, emptiness is a kind of existence, and you have to fill yourself with the existence of emptiness.

3. The more transparent something is, the more mysterious it is. The universe itself is transparent. As long as your eyesight can reach it, you can see as far as you want, but the more you look, the more mysterious it becomes.

4. Nothing can exist forever. Even the universe will one day perish. Why do humans think they should exist forever?

5. I think I have experienced many vicissitudes, but in fact I am just a toddler. I think I have mastered the secret of competition, but in fact I am far from qualified to compete.

6. I have been a lazy person since I was a child. When I lived in school, I never washed the dishes and never folded the quilt. I was not interested in anything. I was too lazy to study or even play. I was in a daze every day. Goofing around.
