In the end of the world when supplies were scarce and dangerous, they used humor and wisdom to resolve the crisis, and outlined the tenacity and warmth of human nature in struggle and redemption. They supported each other, broke through despair, and led the survivors to actively build a new home of hope. The story uses "the great wisdom of little people" as a clue. Through the growth and mutual influence of team members, it gradually reveals the power of unity and laughter in dealing with suffering.
