《旧五代史·后晋·列传八》
碰上复试进士，卢质以 后从谏则圣 为文题，以 尧、舜、禹、汤、倾、心、求、过 八字为韵，按旧有赋例用韵当为四平四仄，卢质所出韵字却五平三仄，因此大为有识之士所讥笑。
会覆试进士，质以 后从谏则圣 为赋题，以 尧、舜、禹、汤倾心求过 为韵，旧例赋韵四平四侧，质所出韵乃五平三侧，由是大为识者所诮。
When he came across the re-examination Jinshi, Lu Zhi used 以后从谏则圣 as the title of his essay, and used 尧、舜、禹、汤、倾、心、求、过 as rhyme. According to the old rules, there should be four flat and four oblique tones in the rhyme, but the rhyme characters that Lu Zhi put out had five flat tones and three oblique tones, which was greatly ridiculed by insightful people.
