Of course It is the golden section of 0.618.

The Golden Section and Plastic Surgery in the Beauty of the Human Body

The Golden Section, also known as the Golden Rule, refers to a certain mathematical proportional relationship between the parts of a thing, that is, dividing the whole into two parts. The ratio of the most part to the smaller part is equal to the ratio of the whole to the larger part. The ratio is 1:0.618 or 1.618:1, that is, the long section is 0.618 of the whole section. 0.618 is recognized as the most aesthetically significant proportion number. The above ratio is the ratio that most arouses people's sense of beauty, so it is called the golden section.

According to Professor Lin Maochang, a beauty expert at Xijing Hospital of the Fourth Military Medical University, in recent years, when many scholars studied the relationship between the golden section law and human body beauty, they found that there are many factors related to the appearance and body structure of bodybuilders. The points, triangles, rectangles and indices closely related to the Golden Section show the important application value of the Golden Section in human body beauty and beauty practice.

■The golden point of the human body

The so-called golden point refers to a line segment where the ratio of the short segment to the long segment is 0.618 or an approximate value. The human body has many golden sections, which are one of the foundations of human beauty.

The navel is the golden point in terms of the overall human body structure. The ratio between the navel above and below the navel is 0.618:1.

From the top of the Adam's apple to the navel, the Adam's apple is the dividing point, and the ratio between them is approximately 0.618.

The line connecting the hairline in front of the eyebrows to the base of the chin, the dividing point between the upper 1/3 and the lower 2/3.

The line connecting the subnasal point in front of the hairline to the base of the chin, the dividing point between the lower 1/3 and the upper 2/3.

The line connecting the lips, nose, and chin, is the dividing point between the upper 1/3 and the lower 2/3.

Front view of the corner of the mouth, the dividing point between the left (right) 1/3 and the opposite 2/3 of the horizontal line of the oral cleft.

The dividing point from the acromion of the elbow joint (olecranon) to the tip of the middle finger.

The dividing point from the sole of the knee joint (patella) to the umbilicus.

*** *** Vertical line, dividing point from clavicle to groin.

■The golden rectangle of the human body

The golden rectangle refers to a rectangle with a width-to-length ratio of 0.618 or a value close to this value. There are also many golden rectangles in the human body, which are also one of the foundations of human body beauty.

Head profile: The head is long (from the top of the skull to the chin) and wide (the distance between the zygomatic arch protrusions on both sides).

The width of the facial contour at the eye level is wide, and the distance from the front hairline to the base of the chin is long.

The nose contour is wide, and the distance from the root of the nose to the lower point of the nose is long.

When the lip contour is at rest, the distance between the upper and lower lip peaks is wide, and the distance between the corners of the mouth is long.

The average of the shoulder width and hip width of the trunk outline is width, and the distance from the acromion to the bottom of the hip is length.

Hand outline: When the fingers are together, the horizontal line of the metacarpophalangeal joint is wide, and the distance from the wrist joint to the tip of the index finger is long.

■Human body golden index

The golden index, which is the proportional relationship between two line segments, is 0.618, or approximately this value. This proportional relationship exists between many line segments in the human face, trunk, and limbs.

Nasolabial index is the ratio of the width of the nose to the width of the corner of the mouth.

The eye-labial index is the ratio of the width of the distance between the corners of the mouth and the width of the outer canthus of the two eyes.

The upper and lower lip height index is the ratio of the upper and lower lipstick heights at the midline of the face.

The eye-surface index is the ratio of the distance between the outer canthus of the two eyes to the surface width of the eye level.

Limb Index The line connecting the acromion to the tip of the middle finger is the length of the upper limb, and the line connecting the iliac crest to the sole of the foot is the length of the lower limb. The ratio between the two is approximately 0.618.

■The Golden Triangle of the Human Body

An isosceles triangle with a waist-to-base ratio of 0.618 or an approximate value, and whose internal angles are 36゜, 72゜, and 72゜ respectively, is a golden triangle. The golden triangles of the human body include: the external nose looks like a golden triangle when viewed from the front; the external nose looks like a golden triangle when viewed from the side; the triangle formed by the tip of the nose root and the corners of the mouth on both sides; and the triangle formed by the end points of the shoulders and the center of the head. In addition, for a well-proportioned person, the ideal ratios of weight and height, waist and bust, waist and hips are also close to the golden section.
