From the physiological and aesthetic point of view of the nose, it should be symmetrical, the angle should be appropriate, and the height-width ratio of the bridge of the nose should be appropriate. Then the harmonious curve of the nose can be deduced from the connection between the nose and the whole face, even the whole figure, as well as personal temperament and professional habits. This is a perceptual judgment, which requires a profound grasp of human aesthetics, facial aesthetics and psychological aesthetics. This is a way to deal with the geometric beauty of nose structure, the harmony between nose and human face and temperament, and the natural beauty. Two thirds of the length of the nose is the height of the nose. On the other hand, the angle between the nose and face of men is 36 degrees, and that of women is 34 degrees. The width of the alar is about between the vertical lines of the two inner canthus, and the width of the nasal bone is less than the distance between the two inner canthus.
