1, ghost marriage is to find a spouse for the dead. Some boys and girls died for some reason after they got engaged, but they didn't wait until they got married. At that time, the old people thought that if they didn't get married for them, their ghosts would do mischief and make the family uneasy. So we must hold a ghost wedding ceremony for them, and finally be buried together, become husband and wife, and be buried together. In case there are solitary graves in the fields of men and women.
2. In the past, people were generally superstitious about the so-called "geomantic omen" in cemeteries, believing that the appearance of orphan tombs would affect the prosperity of future generations of family houses. At that time, some "Mr. Feng Shui" (known as "masked jade" in ancient times) strongly encouraged this ghost marriage in order to make more money. Ghost marriages often occur in aristocratic or rich families, and poor families generally do not engage in such activities.
