It is not a sex organ and has no particularly sensitive cells, but it contains visual beauty, which is the potential reason for the popularity of navel-revealing clothes. Seen from the front, the navel is located at the intersection of the vertical and horizontal lines of the human body, and the waist line intersecting with the navel is regarded as the golden section line. Judging from the curvaceous beauty of women, the protrusion of nipples and buttocks requires a soft transitional abdomen, so the navel in the center of the abdomen is very important. But just as the eyes are big and small, and the bridge of the nose is high and low, so is the navel. Therefore, makeup and surgical beauty for navel are becoming more and more popular, just like eyelid cutting and rhinoplasty. In fact, people's attention to the beauty of navel did not start today. In some foreign nationalities, the abdomen around the navel is one of the important parts of tattoos. Like belly dancing in India, the dancer's waist swings to give off a sultry feeling, and the belly of the belly dancer is carefully decorated. These navel rings, tattoos and other decorations, coupled with the slender waist twisted like a water snake, make it hard for you not to be tempted.

Everyone loves beauty, and navel beauty is understandable, but certain principles should be mastered. However, now some lawless people have come up with the idea of navel beauty, claiming that the "shallow navel" symbolizing short life can become the long-lived navel of Nanshan, and the "crooked navel" symbolizing infertility can become the "happy navel" of many children. In fact, the so-called "crying umbilical cord", "laughing umbilical cord" and "loving umbilical cord" are all people's subjective imagination, which is not only inconsistent with the actual shape, but also impossible for them to predict the future. In fact, even a highly skilled plastic surgeon can hardly create a navel as vivid as a cat's eye or a smile.
