Since ancient times, Lapa has been a sacrificial ceremony used to honor ancestors and gods (including the gods of doors, households, houses, stoves and wells), praying for a good harvest and good fortune.

Later, with the prevalence of Buddhism, the Buddha became the day of the fusion of the day and the day of the wax, in the field of Buddhism is known as the "Dharma treasure festival". It was fixed on the eighth day of the first month of the Lunar New Year from the Northern and Southern Dynasties.

Why Lahai:

Lahai, Lahai and other sayings have a lot to do with the pre-Qin Dynasty "wax festival". In that era when civilization was in its infancy, agricultural production was the top priority in order to have enough to eat. Legend has it that from the ancient sage king Shennong or Emperor Yao, wax sacrifices were performed in December at the end of the year in return for the blessing of the gods of agriculture.
