How to preserve crabs:

Stored in the fresh-keeping room of the refrigerator. When buying hairy crabs, merchants usually tie the crab legs with ropes. When we go home, we don't have to untie them. Putting it directly into the refrigerator can avoid the crab's struggle and reduce the crab's physical consumption.

Just put a wet towel on the crab after putting it in the refrigerator. This method can be kept within 3 days, and eat the less lively ones first.
