A belt is a belt used to tie the waist, a belt. If it is leather, it is also called a belt. China didn't need buttons in his early days, but only sewed a few small ribbons on his skirt to tie the knot. The name of this small band is "Jump". The waistband refers to the bone connecting the hind limbs and spine of vertebrates. The human belt bone is composed of ischium, pubic bone and ilium.
