How did a two-dollar box of small crabs bought at the grocery store disappear overnight?

Putting it for one night will make crabs taste bad and even die and deteriorate. The following methods are recommended:

1, put it in the refrigerator and cover it with a wet towel for a few days. Touch the crab's eyes with your hand, and the dead crab will not respond.

2, put it in a bucket, but the height of the water can't pass the crab's body, otherwise the crab will die of lack of oxygen. It's best to have a bathtub at home, because the bathtub is very smooth and crabs can't climb out. Around September of the lunar calendar, female crabs have mature gonads and plump meat; After October of the lunar calendar, male crabs have mature gonads and plump meat, so they should be eaten at the right time. Crab should not be eaten with sweet potato, pumpkin, honey, pear, pomegranate, tomato, cantaloupe, peanut, snail, celery, persimmon, rabbit meat and Schizonepeta; Eating crabs without cold drinks will cause diarrhea.
