Foot binding horror

Just read in detail about foot binding in ancient China. I always thought they just wrapped up the feet during infancy to stop them from growing.

But, no! They wait till the girl is 4-7 years old, then break her toes and arch bones so that the toes can curl under the sole. Without anaesthesia.

After wrapping the monstrous creation tightly, the girl is then forced to walk on her broken feet so her weight can help crush them into shape. The feet are crushed and rebound daily for like two years! WTF is wrong with people?!
