1. First clean the prawns, find the position of the shrimp head and body, and be sure to clean them when cleaning the shrimp.

2. Then use a little force to break open the shrimp head and body where they intersect. It should be noted that you should break it gently and not too hard.

3. If the shrimp head is broken off, the shrimp thread and the stolen goods inside the shrimp head will be disconnected, and the shrimp thread cannot be pulled out.

4. Squeeze out the dirt from the shrimp head and lift it out with your hands. The shrimp thread will also be brought out.

5. When pulling the shrimp thread, be sure to pull it slowly and gently, otherwise it will be easily broken and the remaining shrimp thread will remain inside the shrimp.
