1. Don’t run around when you want to steam live crabs. You can tie them tightly with a rope, or you can use wine to anesthetize them before steaming them. If the crabs are tied with a rope when you buy them, do not remove the rope, tie them with another thread, and then steam them in a pot. If you don't prick the crab when you buy it, put the crab in light white wine for 10 minutes, and the drunk crab will not struggle.

2. Live crabs can be cleaned with a toothbrush. First, put the crabs in clean water for about 2 hours so that they can naturally excrete dirt. Then rinse with clean water. Then grab both sides of the crab with one hand, carefully clean the crab's abdomen, back, pliers and feet with a toothbrush, and finally open the crab's belly cover and scrub.
