SYNOPSIS: “Red bean” is a metaphor in Chinese culture. It refers to love for and concern with relatives and old friends.
The fall of the earth is caused by human selfishness, haughtiness and dismissal. If we travel to future and look back at ourselves of today, we will realize that we have lost our “true love” and it is too late. The outer space that houses humanity is like purgatory, and the earth is the only shelter for human life. It is better to protect our “home” from now on than to miss our “home”.
