1. First, fold the bisectors of the two corners at one end of the paper in half, and only need to fold them in half for a short period. Then, fold the paper in half vertically, leaving a crease and opening it.

2. Turn over: overlap the two corners with the center line respectively to form a triangle at the top, fold the top corner of the triangle to the midpoint of the opposite bottom, leaving the first crease open, and then overlap the first crease with the bottom of the triangle, leaving the second crease open.

3. Then divide the area between the above two creases 1 and 2 into three equal parts and fold the bisector, that is, fold two creases between the two creases.

4. Turn it over: fold the top corner to the top crease 3, open it after leaving the crease, then fold the top corner to the crease 4, and open it after leaving the crease. At present, there are 6 parallel creases in the triangular area.

5. Turn it over, that is, fold the paper edges on both sides of the whole paper to the center line, then pull the paper layers in the triangular area apart, and readjust the creases for folding.

6. Turn over: Fold the tail of the bill up and down by 90 degrees along the bottom crease, and fold out two crossed creases, then fold both ends in half along the intersection, fold up the transverse crease passing through the intersection, and then open the paper.

7. Pull the paper from below, adjust the "M"-shaped crease just folded on the paper, take the diagonal crease as the peak line and the short straight lines on both sides as the valley line, adjust the folding, and lay the folded triangle down on the original triangle.

8. Turn it over and adjust the crease. Align the edges of the paper on both sides of the triangle with the center line and fold inward. The whole edge of the paper should be folded over. Then fold the triangle upward, and the crease is located at the crease on both sides of the paper, which is also the crease that existed before, and then fold the triangle downward, and the crease is the middle line of the two creases, and the formed protrusion pushes down.

9. Fold the triangle inward for the second time, then fold it back and flatten it down to form the second bulge. Then fold the paper edges on both sides of the second protrusion to the center line respectively.

10. Fold the lower triangle into an angle to cover the upper triangle, then spread paper seams on both sides of the folded angle, and then spread them to protrude as the dragon's nose.

1 1. Pinch the diagonal corners respectively, and push the crease of the back short line to the front number 2 while pinching the corners. The crease we folded before can make the pushed crease fit the paper seam in two places.

12. Turn over one side of the faucet and bend the two oblique sides connecting the dragon body inward into an arc. The other side does the same.

13. Unfold the paper from the bottom, and fold the edges of the paper inward by one-third of the width to restore the folded state. At the joint of the faucet and the dragon body, the dragon body is folded down by 90 degrees, and then it is folded back to the horizontal direction through twists and turns. The faucet part is folded.

14. Now deal with the dragon tail: open the whole edge of the end of the paper money, that is, open the first third of it, align the side corner with the center line and fold it inward, then restore the folding of the first third, and at the same time fold out the connecting line between the joint and the top corner, press it down and dial it in the opposite direction. The other side does the same.

15, dragon body reprocessing: Fold the whole dragon tail to the faucet, leave a distance and then fold it back. Through such twists and turns, the dragon body changes, and the length of the dragon body determines the number of twists and turns.

16. Finally, turn the upper paper of Wei Long in the opposite direction, and a mini dragon will be folded.
