1. Keep intact: Store unopened food in the refrigerator. Ensure that the packaging of food is not polluted or damaged to prevent the growth of bacteria.

2. Refrigeration: If the package has been opened, but there is food left, you can put it in a sealed container and put it in the refrigerator. Please be sure to put the leftover food in the refrigerator within 2 hours.

3. Heating before eating: When you are ready to eat the plate-burning set meal again, you can take it out of the refrigerator and heat it to a suitable temperature. Be careful not to put the plastic package in the microwave oven, but transfer the food to a microwave oven plate or tableware suitable for heating.
