Lin Wanwan slips a jade bracelet onto her wrist—and steps between two worlds. Side A: neon lights, 5G, instant ramen, MRI machines—an age of abundance where food is fast and friendships sometimes slow. Side B: Tang-dynasty sunshine, cracked earth, locust clouds, emperors who ask villagers to skip meals so soldiers can march. A “golden age” that growls with hunger. Lin has no grand plan—only a wish: let the little bean who waits for her at the gate eat his fill, let the gray-haired elders who calls her “treasure” sleep without fear of famine. Lin Wanwan wants to bring small changes to the world she loves, so the family she cherishes can live a little better, then a little better still—because “I has finally found the place that calls my home.”
