There are three ways to kill crabs: 1\ If you are not afraid of being bitten, just loosen them, then grab the two hind legs directly, then put them under the tap to wash away the sediment and then put them in the pot to steam the birds. 2\ If you are afraid If you bite, just use chopsticks to poke it through the mouth of the crab before it is loosened, and kill it. Then take it to the faucet to clean it, and then steam it in a pot. 3\ Before loosening the rope, flip the crab to the ground. Then use a sharp knife to stab the crab's abdomen, stab it to death, and then clean it and put it in the pot. Of course, this is also a way to avoid being bitten. I usually use method 1. Such crabs are generally more vigorous and fresh
