The first type: free expansion and contraction.

1. Tidy up one of the belts, wrap the belt around three fingers to form an ellipse, wrap it around the back, and wrap it from top to bottom.

2. When winding to the last point, thread the belt tail into the hole and tidy it up.

The second type: pipa knot.

1. Tidy up the belt, leave one hand at the right and left with an appropriate length, come out from behind, circle under your fingers and then return to the top, from tight to loose, and then go down in turn.

2. Finally, pass the tail end of the belt through the last hole, tighten it and tidy up the tightness.

The third type: copper junction.

1, this is very much like a pipa knot. Fold the tape, leaving it about two fingers wide, winding it out from the back, folding it when you go down, and laying it flat in turn when you return to the top.

2. After circulating up and down several times, pass the tail end of the belt through the hole below, tighten it, arrange the belt below and lay it flat.

The fourth type: single rope bow tie method.

1, fold the rope in half to form a circle, and take the rope out of the circle to form a half bow. The rest of the rope is horizontally arranged in a figure of eight.

2. Bypass the general bow just now, put it in the circle at the bottom, and then arrange it so that the bows on both sides are the same size.

Fifth: double bow tie method.

1. The rope wraps around the left hand three times, then takes it out from the middle, and unties the third circle from the hand to form a circle.

2. The top of the rope passes through the circle, and finally the remaining two circles in the hand can be untied.
