2. Put oil in the pot, add onion, ginger and garlic and stir fry.

3. Add crabs, add wine, sugar and spicy powder, stir-fry until the crabs turn red and put them in the pot.

4. Add tofu, chicken soup, simmer for 20 minutes after the fire is boiled, and add a little monosodium glutamate when the pot is out. You can also put some sesame oil. It doesn't matter.

The difficulty is to clean the crabs, which is very important, otherwise there will be a disgusting earthy smell.
