1. First subtract the whiskers and tails of the shrimp with scissors.

2. Then aim the scissors at the joint between the shrimp head and the shrimp body, cut off about two thirds of this place, and keep one third of the joint. Be careful not to blow it up.

3. From the opening where the shrimp tail is cut off, cut it along the ridge line of the shrimp back with scissors. Note: not only cut the shrimp shell, but also cut two-thirds of the shrimp meat, leaving one-third to prevent the shrimp meat from spreading.

4. Cut all the way to the break between the shrimp head and the shrimp body.

5. Then spread the cut shrimp body parts left and right separately (if it can't be spread out, it means that the shrimp meat is not fried in place, so you can cut it slightly with a knife), that is, the third step, one third of the shrimp meat does not come loose.

6. Take out the sausage with a toothpick after unfolding. Then wash the shrimp with running water.

7. Cut the shrimp horizontally into four broken tendons with scissors. Steaming or roasting after the tendon is broken will prevent the shrimp from curling.
