Before cooking with crabs, you can do the following treatments without deliberately killing crabs.

1. Brush crabs under running water with discarded toothbrushes.

2. Cut the pliers with kitchen scissors or break them directly. So you won't get caught. Knock the pliers open with the back of the knife, which will cook faster and be easy to taste.

3. Open the crab shell and take out the crab gills.

4. Remove the navel of the crab and brush off the stains in the gap again.

5. Divide the crab shell and crab body into two parts. If it's a big crab weighing more than 200g, cut it into 4 pieces.

Note: Crabs are tenacious, and their hind legs may move when they are cut in half. Please be prepared in advance. Try to wear gloves; Crabs carry bacteria. If you are accidentally injured, you must disinfect it in time and pay attention to the changes in the wound.
