Ni Ping wrote such a story in The Quotations.
When my mother got married, there was nothing decent in the house.
One day, I told me:
"Start from the beginning of your own combing, your mother saw the washbasin shelf, in order to tell you just in the mirror, your mother will bow his face and look in the mirror.
Slowly, you grow taller, and your mother puts the washbasin shelf up with pieces of wood in an inch and a inch, so that you don't let your eyes look at the mirror.
Later, when you grow taller than your mother, your mother will wash her face and look in the mirror.
Until you leave this home, your face is always right in the mirror, but your mother has always been inappropriate. ”
