According to the legend, in this remote cursed village, there were often people who died unnatural deaths due to natural disasters and man-made accidents, such as car accidents, hanging, murder, and drowning. According to local customs here, these ways of dying are called "violent death". The local villagers believe that the souls of such deceased people are restless and carry a heavy ominous aura. If they are buried in the ancestral graveyard, it will cause unrest in the home and affect future generations. Hence, the custom of nocturnal burial came into being. Only during starless dark nights, strong men from the village would carry the bodies to remote mountain hollows and bury them in the wilderness far away from the ancestral graves. The details of this night burial custom, however, have always been shrouded in mystery and unknown to the public. This is also what Yu Guang has always wanted to understand.
