In addition to raw materials such as cowpea, adzuki bean, peanut and jujube, shredded pork, radish, cabbage, vermicelli, kelp and tofu are also added. The Laba Festival is also called the Laba Festival, the Laba Festival, the Maharaja or the Buddha's Day of Enlightenment. Originally, in ancient times, people celebrated the harvest and thanked their ancestors and gods (including door gods, household gods, house gods, kitchen gods and well gods). In addition to the activities of worshipping ancestors, people also had to chase the epidemic. This activity originated from Nuo in ancient times (the ritual of exorcising ghosts and avoiding epidemics in ancient times). One of the medical methods in prehistoric times was to exorcise ghosts and cure diseases. As a witchcraft activity, the custom of beating drums to drive away epidemics in the twelfth lunar month still exists in Xinhua and other areas in Hunan Province. Later, it evolved into a religious festival to commemorate Buddha Sakyamuni's enlightenment. The Xia Dynasty called La Ri "Jiaping", the Shang Dynasty "Qing Si" and the Zhou Dynasty "Da Wax". Because it is held in December, it is called the twelfth lunar month, and La Worship is called the twelfth lunar month. The twelfth lunar month in the pre-Qin period was on the third day after the winter solstice, and it was fixed on the eighth day of the twelfth lunar month in the Southern and Northern Dynasties. Shuowen contains: "Three days after the winter solstice, La Worship Hundred Gods will be guarded." It can be seen that the third garrison day after the winter solstice was the twelfth lunar month. Later, due to the intervention of Buddhism, the twelfth lunar month was changed to the eighth day of December, and it has become a custom since then. Why the end of the year is called "la" has three meanings: one is "la, which means the alternation of the old and the new" (recorded in Sui Shu Etiquette); Second, "the wax hunter hunts together", which means that hunting in the field can get animals to offer sacrifices to ancestors and gods. "Wax" comes from "meat", which means "winter sacrifice" with meat; Thirdly, it is said that "those who wax wax, drive away the epidemic to welcome the spring", and Laba Festival is also called "Buddhist Daoism Festival", also known as "Daoism Society". In fact, it can be said that the eighth day of December is the origin of Laba Day. According to legend, the founder of Buddhism, Sakyamuni, practiced in the deep mountains and sat quietly for six years. He was so hungry that he wanted to give up this suffering. He happened to meet a shepherdess and gave him chyle. He sat cross-legged under the bodhi tree after eating, and became a Buddha on the eighth day of December, and started the "Buddha-to-Daoism Festival" to commemorate it. Believers in China are devout, so they merged with the "La Ri" to form the "Laba Festival", and also held a grand ceremony.
