The famous quotes in "The Three-Body Problem" include:

1. We are all bugs in the gutter, but someone still has to look up at the stars.

2. As long as the moon shines, Constantinople will not fall.

3. You must know that a literary character’s behavior in ten minutes may be a reflection of her ten years of experience.

4. If there is a God. When humans think, God laughs; if humans don’t think, God doesn’t even bother to laugh.

5. Even if it is four light years close at hand on a cosmic scale, it is unimaginably far away for fragile life. In this Enoto and Enoue in space, no connection is possible. As thin as a gossamer.
