1. We put the food to be heated in the microwave bowl and cover it. Note that the lid of the microwave bowl is not tightly sealed, so leave a vent hole. The microwave oven can't put too much food at a time, and it can't exceed about one-third of its capacity. Next, cover the microwave oven and turn the button to select the heating power and time.

2. If you only heat the rice, you can choose to heat it for about 2 to 3 minutes. If we heat soup, we can heat it twice and so on. If we heat food with skin, we can punch holes in the food with toothpicks before heating it.

3. If we heat pasta, we can spray some water before heating to avoid the heated food being too dry. When using microwave to heat food, pay attention to eggs, milk in sealed boxes, fruits, etc. You can't heat it in the microwave.

4. When it's time to heat the microwave oven, it will sound a prompt to remind us to take out the food in time. If food is left in the microwave for a long time, it is easy to breed bacteria. Unplug the power supply after using the microwave oven, and clean up the oil in the microwave oven in time.
