The term "mirror-image person" refers to someone whose organs, like the heart, liver, spleen, and gallbladder, are positioned opposite to those of a normal person, with the heart and spleen on the right side and the liver on the left.
The positions of the heart, liver, and spleen appear as though they are a mirror image of a normal person's organs. The occurrence rate is about one in a million, quite rare.
"Mirror-image people" appear no different from others in their facial features, hands, and feet, showing no abnormality that can be seen, only discovered through organ checks or X-ray tests.
Most mirror-image people's organs have some congenital deformities, leading to illness and death in infancy. However, some mirror-image people's organs develop normally, allowing them to live no differently from ordinary people, healthy and long-lived.
