Origin
There are two popular stories of the origin of Laba Festival.
One story goes that Laba Festival was originated from Sakyamuni. He was saved by a shepherdess with her lunch -- porridge made with beans and rice when he fell into unconsciousness by a river in India from exhaustion and hunger. This enabled him to continue his journey and on the eighth day of the twelfth lunar month after six years of strict discipline Sakyamuni finally realized his dream of full enlightenment. In order to commemorate this incident, every year at the Laba Festival Buddhists eat Laba porridge and offer it freely to the poor.
The most popular custom of Laba Festival is eating Laba Rice Porridge. Laba rice porridge is quite delicious with multiple ingredients as glutinous rice, red beans, millet, Chinese sorghum, peas, dried lotus seeds, red beans, dried dates, chestnut meat, walnut meat, almond, peanut, etc. As a nourishing and healthful food, Laba porridge serves as a symbol of good fortune, long life, and fruitful harvest.
Another custom is the soaking of Laba Garlic, which is particularly popular in northern China. Garlic is soaked in vinegar for twenty days starting from Laba Festival and then the garlic is used alongside Chinese dumplings (or jiaozi) around Spring Festival.
