Human trafficking refers to a kind of torture that turns people into pigs. It is to chop off limbs, cut off nose, gouge out eyes, inject copper into ears, make ears deaf, pour black medicine into throat, cut off tongue, destroy vocal cords, and make ears unable to speak. And throw it in the toilet. (Mrs. Qi's hands and feet were cut off, her eyes were gouged out, her ears were stuffed, she drank some medicine and was put in the toilet, so she was called a "man". See Historical Records Lv Hou for details. )
