The schematic diagram of knotting method with rope is as follows:

1. Cross two belts, one in front of the other.

2. Wrap the front belt around the back, and then hang it down between the two belts to tighten it and tie a slipknot.

3. Fold the back belt into an S-shape, put it on the right along the belt direction, and then wrap the front belt around the bow.

4. After the front belt bypasses the bow on the right, fold the bow aside and tighten it.
