Legend has it that thirty years ago, Weijia Village on the north bank of the Wei River was built on a mass grave. A few years ago, due to demolition, graves were not allowed to be built on the farmland in Weijia Village and surrounding areas. Anyone who passed away must first be taken to the county crematorium for cremation, and then the ashes were buried in the newly built cemetery five miles north of the village. However, some people always do not believe in evil. The Liu family in the west of the village did not cremate the deceased old man Liu as required by the notice. Instead, they buried him in their own farmland and prepared a good coffin and shroud.
