A person's upper width and lower width may mean that the part below the chin of a woman is thinner than the part between the lower lip and the lower nose. This facial feature is considered to be related to a person's personality, fate and health in medical beauty and physiognomy.

In physiognomy, man is one of the main manifestations of life, which is considered to be related to his life span, wealth and family. Therefore, a woman with a wide top and a narrow bottom may be considered to have a long life, good luck and a happy family.

However, this view is not supported by scientific evidence, but a traditional concept. At the same time, the formation of the five senses is related to many factors such as heredity, growth and development, living habits and so on. Its relationship with personal destiny should not be overemphasized.
