It's still impressive---imagine writing 1000 words of English without reusing any function words like "the", "it", "of", "is". And just to show off, the Qianziwen holds a bunch of those words for the very last line!
E.g. the first rhyming couplet 天地玄黃 宇宙洪荒 was translated somewhat verbosely by Nathan Sturman as "The sky was black and earth yellow; space and time vast, limitless" but why many words when few do trick? "Dark sky, yellow earth; vast space, barren time."
To make it rhyme, you could replace "earth" by "lime" (referring to calcium oxide, not the fruit) but that would be very barren indeed.
How about:
> Gadsby is a [260-page] 1939 novel by Ernest Vincent Wright which includes only four words that contain the letter E, the most common letter in English.
> [The novel] "A Void", translated from the original French La Disparition (lit. "The Disappearance"), is a 300-page French lipogrammatic novel, written in 1969 by Georges Perec, entirely without using the letter e, following Oulipo constraints. [0]
