1. Store in clean water. If you only want to save it for a short period of time, we can use the method of soaking in clean water. It's very simple, just put the zong leaves directly into the water and soak them, changing the water from time to time. In this way, the rice dumpling leaves can be stored for about a month. This method can keep the rice dumpling leaves green and fresh for a month.

2. Hanging method. Another method is to put the fresh rice dumpling leaves in a cool and ventilated place and hang them to air dry. Then soak them until they are soft. After soaking, the rice dumpling leaves will become soft. As fresh as when you bought it. Using this method to preserve rice dumpling leaves can last for several months, which is very practical.

3. To store in the refrigerator, clean the rice dumpling leaves first, then dry the water on the rice dumpling leaves, put them in a clean fresh-keeping bag, exhaust the air inside, tie the bag tightly, and put it in the refrigerator. That's it. When using it again, let it thaw naturally, then soak it in some water before use. This method can be preserved for at least a year, ensuring the freshness and toughness of the rice dumpling leaves. They will still be fresh and easy to use when used to make rice dumplings during the Dragon Boat Festival next year.
