It is relatively simple to keep the bought crabs in a state that they can be eaten in about three days: choose crabs with strong vitality, tie their feet with gates to reduce the physical consumption of crabs, then put them in the freezer of the refrigerator and cover them with wet towels for preservation.
When eating, choose crabs with insufficient vitality and sufficient vitality every day to continue to be preserved. ? The way to tell is to touch the crab's eyes with your hands, and eat it first if you are not sensitive.

Tips for choosing crabs:
1, check the connection between the limb and the body.
The feet of fresh crabs are closely connected with the body, so the feet will not droop when lifting crabs. The stale crab will obviously relax at the rotatable place where the limbs meet the body. When you lift the crab by hand, you can see that the limbs (feet) sag downward.
2. Look at the "stomach print" above the navel.
Crabs mostly feed on humus. After a period of death, the stale contents of the crab's stomach will rot, and black marks will appear on the crab's belly and navel.
