Is Laba Festival a traditional festival in the north?

The eighth day of the twelfth lunar month is Laba Festival, also called Laba Festival. Ancient people sacrificed their prey to God at the end of the year, usually called La Worship. Later, it is said that Sakyamuni became a Buddha on this day, which is also called "Taoist Festival". However, the custom of Laba has a long history, and it was originally a sacrifice to ancestors. Custom Code: "The Book of Rites was passed on to Sun, Jia Ping, Qing Si and Zhou Wax. Turn China people into wax. The wax man is still alive. It is said that Tian Tian hunted and sacrificed animals to his ancestors. " Only after it was combined with Buddhism did it change, changing the nature of Laba Festival.
