Crab is a fresh aquatic product, which can be preserved for a short time after leaving water, and the purchased quantity can be eaten in about 3 days.

Preservation is relatively simple: choose vigorous crabs, tie their feet and pliers to reduce their physical consumption, and then put them in the freezer of the refrigerator and cover them with wet towels for preservation. When eating every day, choose the crabs with insufficient vitality and sufficient vitality to continue to be preserved.

Note: live crabs can only be refrigerated, but not frozen. Freezing will freeze the crabs to death, and the frozen noodles will have no taste.
