A straight line (each hair naturally hangs to the horizontal line and is cut at an angle of 0 degrees)
2.A line (each hair naturally becomes a diagonal line and is cut at an angle of 0 degrees, also called a river line).
3. Circular line (each hair naturally falls to a random arc to cut an angle of 0 degrees, and the position of the arc determines the shape of the circle)
4. Classic stacking (gradually stacking the weight, outward away from the head, the A line is cut at an angle of about 45 degrees, and the weight line is at the occipital bone)
5. Circular stacking (gradually stacking the weight, following the head shape, cutting the arc at about 45 degrees, and positioning determines the prototype shape).
6. Square stacking (gradually stacking weight, internal angle, straight cutting at an angle of about 45 degrees, parallel walking)
7. Circular removal (each partition keeps the same length and proportion, the internal weight does not increase or decrease arbitrarily, and the arc is cut into a 90-degree angle).
8. Square removal (all four sides of the head "top, back, left side and right side" are removed, and the straight line is cut at a 90-degree angle)
9. Reverse head shape curve (curve opposite to the natural head shape trend, short in the middle and long on both sides, cut to about 90 degrees to keep the hair length and remove the hair amount to the greatest extent).
