1. Use scissors or chopsticks to poke into the crab's mouth. Generally, crabs are tied up with a rope, and the rope is removed after being stabbed to death, otherwise there is a risk of being pinched. Moreover, the crab will not necessarily die if the rope is removed. The safest thing is to simply break its two pincers.

2. After being disassembled, it is divided into two parts: crab shell and crab body.

3. There is a crab stomach (a bag with water inside) hidden in the crab shell. You need to find it and clean it out (the reason is that crabs are cold in nature, and the stomach, lungs, and mouth are Disposal can reduce the impact on the body), and then use a brush to clean the crab shell and it is considered finished.

4. Remove all parts of the crab body, crab mouth and crab lungs. Use scissors to gently hold the mouth and break it off by the roots. Remove the lungs and crab heart by hand. Then use a brush to clean the limbs, the inside of the body, and the back, and the crab body is finished.
