Head and body refers to an aesthetic standard of the ratio of height to body. Specifically, the ratio of the length of the body to the height is 7: 1, that is, the length of the body is one seventh of the height, so the 7 heads and the body are about 1.74 meters. Head and body are just an aesthetic standard, which may not be applicable to all women. Height is influenced by genetic and environmental factors, and everyone's height is different. Body proportion is also affected by many factors, such as bone structure, muscle and fat distribution, etc., and height cannot be used as a measure.
