### Noun

日月
* (literally) sun and moon
    From: Zhuangzi, circa 3rd – 2nd centuries BCE, translated based on James Legge's version
    Gù shàng bèi rìyuè zhī míng, xià shuò shānchuān zhī jīng, zhōng duò sìshí zhī shī, zhuìnuò zhī chóng, xiàoqiào zhī wù, mòbù shī qí xìng. [Pinyin]
    It is just as if, above, the brightness of the sun and moon were darkened; as if, beneath, the productive vigour of the hills and streams were dried up; and as if, between, the operation of the four seasons were brought to an end: in which case there would not be a single weak and wriggling insect, nor any plant that grows up, which would not lose its proper nature.
    From: Han dynasty, Cao Cao, 《觀滄海》(Watching the Blue Sea)
    Rìyuè zhī xíng, ruò chū qízhōng. [Pinyin]
    The sun and the moon seemed to rise From the inside of it (the sea).
