1. Head removal: Gently pinch the head of the shrimp with your hand, apply a slight force to bend it downwards, and at the same time, separate the head from the body to remove the head.
2. Remove the shrimp line: Find the back of the base shrimp, count the position of the second or third section from the head, gently insert a toothpick or scissors into the connection between this section and the next section, gently pick out the black shrimp line upwards, and then use your hand or tool to completely pull out the shrimp line.
3. Cleaning: Rinse the processed base shrimp with clean water to ensure that there are no residual impurities or dirt on the shrimp body and abdomen.
