1. Fold the paper twice along the edge, and then diagonally in the left half twice. After folding the crease, unfold the paper.

2. Fold the left side to the center line, and then fold the two top corners of the paper inward.

3. Fold the top triangle (two layers of paper) to the horizontal centerline, and use the folded crease to fold the paper inward. Fold the top triangle (two layers of paper) to the transverse midline, and fold the paper inward with creases after folding.

4. Fold back according to the dotted line as shown in the figure (note the positions of point A and point B, and the connecting line between AB is perpendicular to the midpoint of the transverse center line of the diamond). After folding the crease, pull the paper along the crease and flatten it. Fold along the dotted line. The other triangle is folded in the same way.

5. Pull the two sharp corners slightly outward, then fold the triangular part inward according to the dotted line and flatten it. Fold and restore with dotted lines. After folding the crease, use the crease to fold the sharp corner inward, and then continue folding, as shown in the figure. Fold according to the dotted line, and the folding method on both sides is the same.

6. Fold back along the dotted line. After opening it, fold it twice again to make a crease. Fold the paper into several parts. Fold the lower crease into equal parts, and then fold it outward. Turn the paper over, fold it alternately in the valley folds, and then fold it. Turn the paper over and fold the crease.

7. Fold the paper into creases and fold the peacock's tail backwards. Tail joint, folded, so that they are connected together. At the tail joint, fold as shown in the figure and connect together. Fold the sides in the same way and shape the head into a circle. Legs are recessed backwards and then folded forward. The claw part is folded forward and the shape is suitable. At this point, the peacock in the unopened state has been completed.
