Amy Tan question? (One of her books)?

Question

In her book "A houndred secret senses"

There is a character, sister named Kwan.

She has "Yin eyes" and can see through

her sixth sense.

Do you know if "Yin eyes" is a real term

used in China; and does anyone know

if this story has any truth to it?

Thanks !!
