1. Zongzi can be stored at room temperature in summer for about 1-2 days, and in autumn and winter for about 3-4 days. It is best to store zongzi in a cool and dark place or in the refrigerator, which can prolong the storage time of zongzi. In addition, meat dumplings are more prone to deterioration than vegetarian dumplings, so it is better to eat meat dumplings that are not refrigerated as soon as possible.

2. The endless zongzi can be preserved in cold water. As long as the water is changed frequently every day, zongzi can be kept in water for about 3-4 days.

3. Unlike the zongzi made now, vacuum-packed zongzi can generally be stored at room temperature in the dark for several months. However, if the outer packaging leaks or swells, it means that Zongzi may deteriorate and it is not recommended to continue eating.
