1. Put the bought big head in artificial seawater for 2 hours and spit out mud and sand. The preparation of artificial seawater is to add 22~27 grams of salt to 1000 ml of clean water.

2. Drain the cleaned big head for later use.

3. Add 400 ml of water to a small pot, then add clear chicken soup, Puning bean paste and ginger slices, and boil.

4. After boiling, add red pepper.

5. The second step is to pour the big head, then quickly pour the cooking wine and mix well with chopsticks.

6. As soon as the big head is opened (about 30 seconds), put the nine-story tower in, mix well with chopsticks, and you can go out.

7. Take out the pot and put it in the bowl, pour some soup into the bowl and tidy it up a little.
