After losing his job, Chen Sui, a former architect, went south alone and accidentally entered the "inner world" where reality and legend overlapped in the old town of Jiangnan. From then on, he began to encounter the land gods, river gods, opera spirits and aliens that had been forgotten by the times. He listened and recorded along the way, witnessing the slow retreat of the old gods as local memories faded. He also relearned how to understand his hometown, family ties and his own life in these stories about forgetting, protection and farewell.
