"Is it really so!" ejaculated T'sui Lue, upon hearing this; while she
smiled and nodded her head. "Now I know all about it! But which is Yang
and which Yin in these fans we're holding."

"This side, the front, is Yang," answered Hsiang-yuen; "and that, the
reverse, is Yin."

Ts'ui Lue went on to nod her head, and to laugh. She felt inclined to
apply her questions to several other things, but as she could not fix
her mind upon anything in particular, she, all of a sudden, drooped her
head. Catching sight of the pendant in gold, representing a unicorn,
which Hsiang-yuen had about her person, she forthwith made allusion to
it. "This, Miss," she said smiling, "cannot likely also have any Yin and
Yang!"

"The beasts of the field and the birds of the air," proceeded
Hsiang-yuen, "are, the cock birds, Yang, and the hen birds, Yin. The
females of beasts are Yin; and the males, Yang; so how is there none?"

"Is this male, or is this female?" inquired Ts'ui Lue.

"Ts'ui!" exclaimed Hsiang-yuen, "what about male and female! Here you are
with your nonsense again."

"Well, never mind about that," added Ts'ui Lue, "But how is it that all
things have Yin and Yang, and that we human beings have no Yin and no
Yang?"

Hsiang-yuen then lowered her face. "You low-bred thing!" she exclaimed.
