The first trick: ① First, put the hairy crabs into a bucket, and then pour a small amount of white wine to remove the fishy smell (just the right amount); (2) when the hairy crabs are in a coma, whip them with tools (it is recommended to use the back of a spatula) until they faint; (3) When you feel dizzy, quickly pinch both ends of the back of the hairy crab with your hands and lift the hairy crab to a level position with your chin, which is convenient for observation; (4) Then pick up the prepared toothbrush and brush it constantly towards the back and abdomen of the hairy crabs that have become flat; ⑤ When brushing, let go of the mentality brush, just like book shoes, don't leave out every corner; ⑥ When the brush is almost finished, check whether there is mud, and do not throw it into another clean bucket. Finally, just rinse it again with clear water. The second measure: ① First, prepare a basin of warm water, that is, just put your hands in the water and don't feel hot (the feet of hairy crabs will take off if they are too hot).

This way, the hairy crabs are at your mercy (they won't pinch your fingers) and will not affect the delicacy of the hairy crabs. ② Then pinch both sides of the hairy crab with your hands, take out a prepared toothbrush, and vigorously clean your back, abdomen and mouth. ③ After inspection and cleaning, clean both sides of hairy crabs and the roots of feet and pliers. (4) Next, grab the pliers by hand, open the abdominal cover, and squeeze out the excrement from the inside out according to the middle; . ⑤。 Finally, clean the dirt in the belly cover of the hairy crab, so that the hairy crab can be regarded as a perfect cleaning.
