Goddess Xia likes people with proper manners and she felt this girl did not have any. She had to teach her but she had to make her receptive to her teachings. So she dominated and humiliated the girl using her bare feet as well as with her pee. She trampled and made her lick her feet before she used her pee to finish what she had started. The girl became obedient and she learned what she was supposed to have learned long ago.
