Tools/materials: swimming crab, clear water, knife, basin.

1, directly peel the crab in half with a knife or hand. First, twist the crab's pliers with your thumb and forefinger to prevent them from being caught, and then use a knife to penetrate the gap between the meat shells and divide them into two parts. Be careful in this step, lest you hurt your hand.

2. Pull out the crab's gills and don't eat them.

3. Pull out the viscera on the crab shell by hand and wash it with clear water.

4. Take out the crab mouth and wash it with clear water.

5. Brush the limbs and body edges of the crab with a toothbrush, peel off the shell behind the crab, throw it away, and finally wash it with clear water. You can steam it directly or cut it in half and fry it in the pan.
