This study examined the burial ground cultural in Liudui. For example, the custom of "gǔlǎodàrén" veneration arose from the respect for the dead and the fear of ghosts. However, the empty space remained after buried bodies were moved to other places for veneration has been used by some "grave cockroaches" to establish empty graves to be sold later. This kind of act is called "hào fén." During immigration, reclamation, and settlement, the Hakka people in Liudui implemented self-defense awareness in their burial ground culture.
