Rinse the frozen crab under running water to remove debris. Sprinkle 2 tbsp cooking wine evenly to reduce the fishy smell.

Prepare the seasoning sauce by mixing all the listed seasonings in a bowl.

In a pot, add anchovy stock and sliced radish. Boil for 3 minutes.

Add onion and zucchini, then adjust the seasoning by adding 2 more tbsp of the sauce.

Add mushrooms, green onion, green chili pepper, and red chili pepper. Simmer for another 5 minutes. Add tofu and reduce heat to low, cooking for 5-7 minutes.
