"This trash is sufficient to kill me!" ejaculated Ts'ui Lü. "What are the Yin and Yang? Why, they are without substance or form! But pray, Miss, tell me what sort of things these Yin and Yang can be!"
"The Yin and Yang," explained Hsiang-yün, "are no more than spirits, but anything affected by their influence at once assumes form. The heavens, for instance, are Yang, and the earth is Yin; water is Yin and fire is Yang; the sun is Yang and the moon Yin."
"Quite so! quite so!" cried out Ts'ui Lü, much amused by these explanations, "I've at length attained perception! It isn't strange then that people invariably call the sun 'T'ai-yang.' While astrologers keep on speaking of the moon as 'T'ai-yin-hsing,' or something like it. It must be on account of this principle."
"O-mi-to-fu!" laughed Hsiang-yün, "you have at last understood!"
"All these things possess the Yin and Yang; that's all right." T'sui Lü put in. "But is there any likelihood that all those mosquitoes, flees and worms, flowers, herbs, bricks and tiles have, in like manner, anything to do with the Yin and Yang?"
"How don't they!" exclaimed Hsiang-yün. "For example, even the leaves of that tree are distinguished by Yin and Yang. The side, which looks up and faces the sun, is called Yang; while that in the shade and looking downwards, is called Yin."
"Is it really so!" ejaculated T'sui Lü, 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-yün; "and that, the reverse, is Yin."
Ts'ui Lü 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-yün 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-yün, "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?"
