From ancient times to the present, people have advocated keeping the whole corpse as dirt. Burning corpses is a great disrespect to the deceased. Only those corpses that have undergone abnormal changes will be burned. Those who burn corpses, called "corpse burners", are an extremely dangerous practice. Burning at midnight, one room per room, one carpenter, closed and locked, if the body undergoes a vicious change, the carpenter will definitely die. Qinhe maintained such a livelihood at the canal dock in Dali during the troubled times. Then the appearance of the "corpse burning reward" made him have no inhibitions.
