How to fold love with paper

The first kind:

Prepare a square piece of colored paper. Fold diagonally and expand. Change direction, fold diagonally, and then expand. Fold the corner in half to the middle. The other corner is folded in half to the top. The right side is folded along the midline. So is the left. Turn the colored paper to the back. Put the two triangles down, left and right inward. Turn the colored paper over again, and love will be completed.

The second type:

1. Fold a square piece of paper diagonally, and then fold it in half along the center line of the triangle to form a cross. Fold the trace, align one leg to form a triangle, fold one corner of the triangle and align it with the center line, as do the other four corners. Pick up the folded triangle and press it down with your fingers to form a square, as do the other four corners.

2. Fold the square formed on one side diagonally downward, and so does the other side. Fold the origami along the seal, just at the center line and the other side of the square, and then fold the origami to the positive side.
