Cheng Gong and Li Jiaqi go way back. Both hailing from dysfunctional families, they grew up together in a Chinese provincial capital in the 1980s. Now, many years later, the childhood friends reunite and discover how much they still have in common. Both have always been determined to follow the tracks of their grandparents’ generation to the heart of a mystery that perhaps should have stayed buried. What exactly happened during that rainy night in 1967, in the abandoned water tower? Zhang Yueran’s layered and hypnotic prose reveals much about the unshakable power of friendship.
