1. Prepare a basin of warm water of about 45°C, which means that it does not feel hot when you put your hands in the water (the hairy crab's feet will fall off if it is too hot). Put the hairy crabs into the water one by one with their belly facing up, and when they turn over, they will have choked on the hot water and fainted. The advantage of this is that the hairy crabs just fainted and are at your mercy and will not pinch your fingers anymore, and it will not affect the deliciousness of the hairy crabs.

2. Take out a toothbrush, grab both sides of the hairy crab, and use the toothbrush to clean the back, abdomen and mouth vigorously.

3. Then clean both sides of the hairy crab and the roots of its feet and claws.

4. The next step is the most critical step. Grab the pair of pliers (use the handle of a toothbrush to lift the joints of the pair of pliers from bottom to top, and use your crab-grabbing thumb and index finger to grasp upward along the base of the pliers. Hold the crab claws. For some fierce crabs, you can press down the claws a few times or tap them a few times) to open the abdominal cover and squeeze out the excrement from the inside out.

5. Finally, clean the dirt and claws in the abdominal cover of the hairy crab, so that the hairy crab is completely cleaned.
