1. Boiling and heating: Cooked rice dumplings can be placed directly into boiling water and heated. The taste will not change after boiling, and they will not get angry as easily as frying.

2. Microwave heating: First put a bowl in the microwave and add an appropriate amount of water. Then put the rice dumplings with the plastic bag removed so that the water does not cover the rice dumplings. This will ensure that the rice dumplings are heated evenly and retain the original taste of the rice dumplings.
