1. Clean mung beans, pick out bad beans and soak them in water for 12 hours.

2. Take it out the next day, pour out the soaked water, take a clean gauze, slightly wet it and cover it.

3. Spray some water to let the gauze soak sideways, and don't have too much water at the bottom. Put it in a dark place and spray water twice a day in the morning and evening.

4. In the first 1 or 2 days, the beans will burst and sprout a little, and then they will continue to grow taller (because they will turn red when they see light, so they are not taken out to take pictures. This is the appearance of the seventh day. The gauze has been pushed up so high that it can be eaten, so I took it out to take pictures.

after 5 or 9 days, the gauze can no longer be covered and can be eaten.
