Selection skills of crabs
1. Look
The high-quality crab has a blue-gray carapace with luster, a white abdomen, golden claws clustered with yellow hairs, a bright color, a round navel protruding outwards, a firm and curved connection of limbs, and a large and healthy body.

Step 2: OK.
For crabs whose visual appearance meets the requirements, they need to be weighed one by one, and the ones with heavy hand feel are fat crabs. This trick is not suitable for river crabs and live sea crabs because these crabs are often tied up.
peel
Peel off the navel of the crab. If there are many neat and condensed crabs in the shell, this crab is a good crab.
