The crayfish killing and cleaning tutorial is as follows:

1, subtract the right pliers first, and then subtract the left pliers.

2, add water to soak, and then clean the abdomen.

3, go to the intestines, twist the tail left and right until it is broken.

4. Grab the twisted tail and slowly pull it out, so that the shrimp intestines will follow.

5. Dig out the inside of the head with the tip of scissors, and the black cystic object, that is, the shrimp stomach, can be cleaned at last.
