You can remove the shrimp line with a toothpick. The method is as follows:

1.

Get a toothpick ready. At the joint between the shrimp head and the shrimp body, the third joint from the bottom, use a toothpick to pass through the shrimp body.

2.

Hold the shrimp body with one hand, and gently pull out the toothpick with the other hand to pick out the shrimp line.

3.

First pick out the shrimp line near the shrimp head, and pull the shrimp line by hand, and the end of the shrimp line near the tail will also be completely pulled out.

4.

Pierce the joint between the shrimp head and the shrimp body with a toothpick, put the shrimp under running water, and wash off the black substance at the joint with a toothpick while picking.

Special attention: the shrimp line must be removed before eating shrimp, otherwise diarrhea and other symptoms may occur easily, and food poisoning may occur in severe cases.
