Steps:

1, take out a piece of bean skin and cut it in half for later use.

2. Cut half a bean skin into strips with a width of about 5 cm.

3. Take one and roll it forward.

4. Then tie the rolled bean skin in a knot, and pay attention to the light technique, otherwise it will break easily.

5. All the bean skins were tied in a short time. Knotted knots must be soaked in water for a period of time before eating to remove the beany smell and impurities.
