Buddhist lay disciples will eat vegetarian food on the 15th day of the lunar month. They believe that one of the functions of eating vegetarian food on the 15th day of the lunar month is that it means eating vegetarian food for the entire month.

The people follow this saying and eat vegetarian food on the first day of the Lunar New Year to express their faith and seek good luck. It also reflects the benevolence of the ancestors for all things. A common saying is that if you eat vegetarian food on the first day of the Lunar New Year, it is equivalent to eating vegetarian food for a whole year, which is intended to pray for blessings and longevity. The so-called life is two, two is three, and three is endless, which means three days is one year, so there is a saying that "eating vegetarian during the Spring Festival will last a year."
