From
曹雪芹 (Cao Xueqin, Qing) self-inscription on 《
红楼梦》 (Dream of the Red Chamber, ~1754):
满纸荒唐言,一把辛酸泪。都云作者痴,谁解其中味?字字看来皆是血,十年辛苦不寻常 (A page of reckless words, a handful of bitter tears. All say the author is mad - who understands the flavor within? Each word seen closely is blood; ten years of toil, nothing ordinary). Cao worked and reworked the novel in poverty over roughly a decade before his early death.
