1, Tie the crab's feet and dahl.

2, put them in the fresh layer of the refrigerator and cover them with a wet towel, so that you can pick the ones with low stamina to eat first when you eat them every day.

3, you can keep the crabs in a plastic bucket, put the crabs in the bucket and can not layer.

4, add water to half the height of the crab's body, followed by inedible crabs must not be washed with water.
