Measuring the length of the foot (that is, the length from the heel to the navel) divided by the total height of the person, the closer the number is to 0. 18 (that is, the golden section? ) indicates that the more balanced and symmetrical the graph is.

Golden section:

The golden section refers to dividing the whole into two parts, and the ratio of the larger part to the whole is equal to the ratio of the smaller part to the larger part, and the ratio is about 0.6 18. This ratio is recognized as the most aesthetic ratio, so it is called the golden section.

In ancient Greece, Pythagoras was walking in the street one day. Before passing the blacksmith's shop, he heard the sound of striking the iron, so he stopped to listen. He found that the blacksmith had a regular rhythm in striking iron, and the proportion of this sound was expressed mathematically by Pythagoras.

The golden section has strict proportionality, artistry, harmony and rich aesthetic value, which can arouse people's aesthetic feeling and is considered as the most ideal proportion in architecture and art.
