The most important festival of the twelfth lunar month is the eighth day of December. It was called "La Ri" in ancient times and commonly known as "Laba Festival". Starting from the pre-Qin period, the Laba Festival has been used to worship ancestors and gods, praying for a good harvest and auspiciousness.

There is a custom of eating Laba porridge on this day. Laba porridge is also called " Seven Treasures and five Flavors porridge". The history of drinking Laba porridge in our country has been over a thousand years. It first started in the Song Dynasty. Every Laba day, whether it is the imperial court, government, monastery or ordinary people's homes, they will cook Laba porridge.

On Laba this day, in addition to worshiping the ancestors and worshipping the gods, there are also mourning for the country's death and pinning grief.
