As the name implies, garlic is brewed on the eighth day of the twelfth lunar month. In fact, the materials are very simple, namely vinegar and garlic cloves. The method is also extremely simple. Put the peeled garlic cloves in a sealable container, such as a jar or bottle, then pour in vinegar, seal the mouth and put it in a cold place. Slowly, the garlic soaked in vinegar will turn green, and finally the whole body will turn green, like jade and jasper.

The main custom of Laba Festival is "drinking Laba porridge" and soaking Laba vinegar. China has been drinking Laba porridge for 1000 years. "Laba" was originally a Buddhist festival. After several generations of evolution, it gradually became a household name. According to legend, on the eighth day of the twelfth lunar month, Sakyamuni watched the stars at night and became a Buddha. Therefore, Laba Festival is also called "Magic Weapon Festival", "Buddhist Taoist Festival" and "Taoist Society".
