1, prepare a basin of clean water and add some white wine, put the crab into the basin, let the crab soak in water for 5- 10 minutes, and all the dirt in the body will be discharged through the stimulation of white wine. At the same time, the crab can also be drunk with white wine. If there is no white wine at home, you can burn it with warm water of 45 degrees.

2. Grasp both sides of the crab cover with your index finger and thumb, and brush the eight crab legs, both sides of the crab cover and crab pliers with your other hand in turn. In particular, the crab claws should be brushed several times, because there are so many hairs on the crab claws that it is easy to hide evil people and shelter evil people.

3. Grab both sides of the crab, open the crab navel and clean the crab belly with a toothbrush. This place will contain a lot of sediment, so it must be cleaned up. Then wash it with running water for several times, and you can cook in the pot.
