It needs to be cooked to get rid of the impurities and dirt outside. Fresh zongzi leaves bought or just picked are dirty and should be rinsed one by one. The leaves wrapped in zongzi are zongzi leaves. Put them in a big pot and boil them for a while. The color should be as below, so that the zongzi leaves are soft and more resilient. Soak in clear water, the leaves will be softer, and the water will easily penetrate, so that boiled zongzi will be cooked easily. Cut off the stalks and sharp parts of the leaves, so that the dumplings will look good and the leaves will not be too thick and neat.

Put the dried zongzi leaves in a cool place, not in a wet place, and just boil them with water when using them. Dry zongzi leaves are soaked in cold water for 2 to 3 hours, and then boiled in cold water for about 4 to 5 minutes, provided that they are put in the pot with cold water until 5 minutes after boiling, and can be wrapped after being picked up, and boiled in boiling water for 40 to 60 minutes.
