Han Song creates a terrifying 2066 where America collapses from climate disasters and political gridlock, while his protagonist Tang Long, a Chinese chess prodigy, witnesses the fall of his rival nation. The novel contrasts Tang's orderly life in China with the chaotic, flooded streets of Washington and New York, where cherry blossoms turn black and genetic mutants roam free. When the flood hits the World Trade Center, Tang's team remains calm while Americans panic, highlighting how political fragmentation prevents rescue efforts. Later, Tang loses his chess skills in a civil war, symbolizing the loss of identity when national pride crumbles. The story also explores the Noah Ark crew, Asian orphans traumatized by American racism, who seek a mythical Spiritual Staff instead of facing their pain. Through Newman, a boy with a tail storing American memories, the book critiques our obsession with nostalgia. Ultimately, the novel warns that no superpower is safe if it ignores climate warnings and clings to rigid systems, urging us to find resilience in human connection rather than technology or national dominance.
