What is the moral and symbol of crab?

The ancients often used crabs as symbols of wealth, and crabs have become one of the important ornaments in traditional culture. People think that crabs have two claws and grow strong. Once they hold something, they won't let it go easily, which means keeping money and locking up unstable partial wealth. Crabs have eight feet. In ancient times, it was also called octopus, which means in all directions. The main function of Octopus is to catch, so people give crab a good wish, hoping that it can make money from all directions, or come from all directions.

How to preserve crabs:

Keep it in the fresh-keeping room of the refrigerator. When buying hairy crabs, merchants usually tie the crab legs with ropes, so we don't have to untie them when we go home. Putting it directly in the refrigerator can also 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.
