Weird Things in My Hometown's Ancestral Hall

My grandfather passed away, and I was forced to return to the village in Wannan, Anhui Province, to guard the ancestral hall. The old ancestral hall is full of gloom, and the taboos spoken by the villagers are more terrifying than the others: Do not light a lantern at night, do not knock on the wooden fish, do not talk to anyone outside the door, and never open the door no matter what you hear. On the first seven nights, the sounds of nails scratching on the door and the old lady crying could be heard outside the door. I unexpectedly awakened the ability to see ghosts and hear residual thoughts, and was forced to get involved in a series of strange things in the mountain village. The drowned washerwoman, the missing cowherd boy, the hanged embroiderer, the haunted old well, the life-threatening ancient tree... Behind every strange thing, there are grievances and regrets buried by time. What I guard is not the ancestral hall, but the human heart; What I understand is not a mystery, but an obsession.
