There is no… without… / all without exception (无…不…/无不)

Structure 无 + X + 不 + Y ("there is no X without Y") · 无不 / 无一不 + verb ("all, without exception")

无…不… (wú… bù…) is an emphatic double negative typical of literary prose and proverbs. In the frame 无 X 不 Y it means "there is no X without Y" (无风不起浪 = "no waves without wind", i.e. every rumour has a source). When 无不 or 无一不 precede a verb, they mean "all, without exception": 无不动容 = "everyone was moved". 无 is the written form of 没有, so this turn of phrase sounds far more literary than the colloquial 没有…不…的, which conveys the same idea in everyday speech.
