First, we must first hold the crab down and stop it from moving, so as to play a role in fixing the crab.

Second, then put the eight small claws of the crab near the center.

Third, next we wet the rope with water, and it will be easy to tie it when it is wet. It seems that the dry rope can't be tied.

Fourth, then, we tied the crabs horizontally with rope, first tied them into a circle, and one end of the rope was fixed to the index finger and middle finger of the left hand.

5. Then we wound the crab horizontally again. When winding, you can't send your left hand You must firmly fix the crab. Be sure to wrap the tongs and claws when winding.

6. Then pass the thread under one end of the horizontal line and wind it vertically. At this time, you can also pick up the crab and wind it up.

Seven, then we wrap it vertically and tie a knot, so that a crab will be tied and it won't crawl around.
