The true diary of a body-retriever on the China-Vietnam border, revealing the ghostly tales of the most mysterious underwater realm in south-west China! During the Sino-Vietnamese War, a pontoon bridge unit emerged and achieved numerous remarkable feats. In peacetime, they volunteered to retrieve bodies and criminal evidence from the waters for the local community in a small town on the border between Guangxi and Vietnam. In the course of their work, they encountered all manner of strange and eerie phenomena beneath the water: water spirits and bizarre corpses, ancient 'zongzi' that had not decayed, ghostly formations around their body-retrieval hooks, and swarms of fish-demons. As the recovery operations continued, terror gradually closed in. How should the river demons they retrieved be disposed of? Have you ever heard of the strange taboos surrounding the cremation of corpses in south-west China? These are records of underwater salvage operations spanning several decades; only now, as these veteran salvage workers approach their sixties, have they begun to recall the eerie incidents they encountered back then.
