2. When cleaning, first grab the place where the lobster's back meets the head and tail, and wash the dirty things on the lobster's abdomen with a longer brush while flushing with water.

3. Grab the head of the crayfish by hand, first cut off the right pliers of the crayfish, and cut off the left pliers in the same way.

4. Cut off the crayfish with double pliers and soak them in clear water for 2 minutes, which is convenient for cleaning.

5. Turn it over and you can clearly see that there are many dirty things on the crayfish. Don't try to save trouble and simply rinse, but try to clean your abdomen with a brush.

6. Brushed crayfish will reveal their pink body.

7. Hold the middle tail nail of the lobster tightly by hand and twist it left and right until it is disconnected.

8. Hook out the black sac inside the shrimp head with scissors and throw it away. This is very, very dirty. Be sure to clean it with scissors until it is clean.

9. Open the abdomen with the scissors prepared in advance, dig out the black cystic object in the head with the scissors tip-shrimp stomach, and slowly rinse the crayfish head with running water to remove the dirty things inside.
