Before the holiday begins in late September, many religious Buddhists from different parts of Thailand clean their houses and stop killing the animals. They avoid eating any meat about one or two days before joining that festival. Furthermore, some supermarkets stock a lot of vegetables and ingredients to sell during these holidays, and some restaurants temporarily change the recipe to cook with vegetables or imitated meats. During the celebration, all participants eat only vegetarian food, wear white clothes and discipline themselves with ten basic holy rules such as; do not drink alcohol, do not have sex, do not tell lies or kills, etc in order to claim their minds and refresh their bodies. They also go to Chinese temples to pray to Buddha and donate money or dry foods to maintain and help those temples, and they believe that it will bring the luck to them and their families.
