"In the face of these arguments," laughed Ts'ui Lü, "everything, from old till now, from the very creation itself, embodies a certain proportion of the Yin and Yang principles."
"You stupid thing!" exclaimed Hsiang-yün smiling, "the more you talk, the more stuff and nonsense falls from your lips! What about everything embodying a certain proportion of the principles Yin and Yang! Besides, the two words Yin and Yang are really one word; for when the Yang principle is exhausted, it becomes the Yin; and when the Yin is exhausted, it becomes Yang. And it isn't that, at the exhaustion of the Yin, another Yang comes into existence; and that, at the exhaustion of the Yang, a second Yin arises."
"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."
