There are many ways. Put the steamed bread directly into the microwave oven container. If it is too dry, sprinkle some boiling water on it or a bowl, and then heat it directly in the microwave oven. Don't take too long, it's easy to dry up. Or you can buy special plastic wrap for microwave oven (ordinary plastic can't) and wrap it in steamed bread to heat it. You can also hang a small steam water box of q6, pour boiling water (warm water or cold water) into the box, put steamed bread in it (just put it in the bowl), then press the "steam button" and then press the time button and the start button. You can also buy a special microwave steamer and heat it directly with microwave.
