Wax sacrifice is a folk traditional sacrifice culture with a long history. The ancients hunted in the twelfth lunar month and sacrificed the captured animals to their ancestors and five family gods. According to the records of custom communication, "the wax Hunter also hunts. Because he hunts animals to sacrifice his ancestors, or receives them, he handed them over and made a big sacrifice for hunting in return for his merit." it can be seen that "wax" means hunting and sacrificing with wild animals or their own poultry.
The objects of wax sacrifice are ancestors and five household gods. The five household gods refer to the door, household, skylight, stove and line (the land inside the door). The date of wax sacrifice was not fixed before the Han Dynasty. After the Han Dynasty, the date of wax sacrifice was set on the third day after the winter solstice.
