Step 1: Kill the crab.

Put scissors or chopsticks into the crab's mouth, and you can let the crab die peacefully. At this time, if you untie the rope, you won't be caught. But some crabs are deadly, and there are still some risks. The safest way is to cut off their pliers.

Step 2: Separate the crab shell from the crab body.

Take the crab belly apart and you will see the crab's Baba. It is suggested that this part be cut off. Then put your thumb into the cut gap and break it hard, and you can separate the crab shell from the crab identity.

Step 3: Treat the crab shell.

Crab's stomach is not recommended. The picture shows the stomach of a crab. Because crabs are cold, removing the stomach, lungs and mouth can reduce the impact on the body. Then clean the crab shell with a brush.

Step 4: Deal with crabs.

The crab's mouth and lungs also need treatment. The crab mouth can be gently clamped with scissors, and then it can be broken with a break. The crab lung and crab heart are circled in the picture. Just take it out by hand. Then clean the limbs and crab body with a brush, and it's done.
