    Your face looks as if it is a bit sized, and people have the impression that the left and right sides of the human body seem to be symmetrical. Because everyone knows that if you make a central axis through the nose to the middle of the legs, then a pair of feet, two legs, a pair of hands, two eyes, a pair of ears, etc., will appear very symmetrical. In addition to this, the distribution of hair, the unevenness of the surface of the human body, is also symmetrical.

    Although the nose and tongue are single, the nose is located on the face, and the tongue is in the middle of the mouth, and their shape is symmetrical. In fact, the left and right sides of the human body are not completely symmetrical. A little experiment can prove it:

    Take a piece of your own front**, divide it into left and right halves according to the midline, and then restore it according to the left half and the right half respectively, and the result will be two different portraits from the original The human body is symmetrical, and the asymmetry is only some slight differences, which are generally normal.
