Winter in Chang'an

**"Winter in Chang'an"** In 2270, nuclear winter enveloped the world. The young man Amu uses a leather notebook to record the last remaining warmth of civilization. When the "Gardener" system awakens, it launches the ultimate test of human civilization—— When we lose half of our food, we choose to share rather than fight for it; When faced with alien ultimatums, we choose dialogue rather than submission; When betrayal is discovered within, we choose redemption over purge. This is an epic story of survivors in the last days, and it is also an ethical reflection on how civilization can regain its dignity in desperate situations. Winter will end, but spring is not the reward— But the moment when we are finally worthy of it.
