In these villages, there are ancient taboos that have been dusted by time. Behind each taboo, there are strange things in the name of "customs" - either the ghosts of the dead are obsessed with it, or there are hidden ghosts in the human heart. Whenever Shen Yan visits a place, he records the local folk taboos and the horrific anecdotes he has experienced, trying to uncover the layers of veil between "custom" and "creepy". The book is divided into volumes by region, and each volume contains 15 independent folkloric horror stories.
