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 before Buddha became a Buddha, but also to commemorate the Buddha's enlightenment on the eighth day of December, ancient Indians ate mixed porridge as a commemoration.
First, you need to soak red beans and corn for 3-4 hours in advance. Then mix other materials and wash them. Finally, all the ingredients are mixed and put into a pot, and enough water is added, and the porridge can be boiled with low fire.
