1. Cut a piece of raw land into thin slices (6, 7 pieces). Wash 2 crabs, remove their feet, cut each one into two pieces and set aside.
2. About 4 bowls of water, boil it with raw land, roll it for 5 minutes, then add crabs. When the crabs are cooked, turn off the heat and simmer. (it takes about 8-10 minutes for the crab to be cooked, depending on its size)
3. Take out the raw land, add a little salt, and drink the soup while it's hot
