Steps:
1. Soak mung beans in advance until they swell completely.
2. Pour out the water and let it germinate naturally.
3. After the mung bean sprouts are finished, rinse them with clear water once, and then cover them with a thick wet cloth.
The next day, when I opened it, the bean sprouts were longer. At the same time, it is necessary to pass water and cover it with a wet cloth.
Another day passed, and the bean sprouts grew taller.
6. Take it out and put it on a plate.
