A TV play about Feng Shui Tomb

The TV series "The Legend of Vendor B" touched a nun: the mayor's wife, a nun in Fuxiguan near Baihu Town, escaped from the coffin after being buried alive by her husband. In fact, all the rich family members were buried in an empty dark room, so they survived. Suddenly, they met a wall, which moved away automatically and entered another dark and narrow passage until they saw a coffin. There are two lines on the wall in front of the coffin: "I live and die, I die and I live". There is a gear-like mechanism next to the coffin. In fact, it is a rotating mechanism under the grave. The grave is separated from the middle to both sides, and you can go out. Because he is a dead man, he often haunts nuns and this grave. Years later, he discovered a secret: remove the skull from the coffin, the lid of the coffin will automatically open, the coffin will be empty, and then the bottom of the coffin will be opened at both ends, and there is a lot of gold buried under it ... Once she saved her daughter, she told her a story in this grave: many years ago, old ni, a nearby nun, died, and people buried her here.
