Forty-Nine Taboos in Vietnam

After his grandfather died, Chen Du found a note among his belongings, which read: There is a single horn in the bell tower, a white cloth in the county pond, ducks singing in the flood pond, and the locust tree at the entrance of the village cannot be cut down. He thought it was an old man's superstition. It wasn't until his cousin's soul was taken away under the bell tower that three red lines appeared on Chen Du's palm - grandpa's abilities began to spread to him. It turns out that grandpa has only done one thing in his life: mediation. It's not about slaying demons or catching demons, it's about understanding what those things trapped under the stone are complaining about and hating, and then helping them to let their anger out. Forty-nine stones were laid across the ground, which my grandfather had pressed down all his life. Now one piece was missing and the rest started to come loose one by one.
