The custom of drinking Laba porridge on Laba Festival comes from Buddhism. The eighth day of the twelfth lunar month is the day when Buddha Sakyamuni became a Buddha. In order not to forget the suffering of the Buddha before he became a Buddha, but also to commemorate the enlightenment of the Buddha on the eighth day of December, ancient Indians ate mixed porridge as a souvenir. Since Buddhism was introduced to China, temples have cooked porridge with fragrant grains and fruits and distributed it to believers and faithful men and women. In the Song Dynasty, the folk gradually formed the custom of cooking and drinking porridge on Laba Festival, which has continued to this day.
