Tzung Tzu is made of glutinous rice and commonly wrapped in bamboo leaves. In the past, almost every family planted bamboos in the yard or near the door for making rice dumplings on the Dragon Boat Festival. Nowadays, the custom of wrapping Tzung Tzu at home has gradually declined, so the market demand of Tzung Tzu is increasing year by year. The Dragon Boat Festival is one of the most important festivals in the year.
