Where does 一丝不苟 come from?
丝 is a thread of silk, and in classical Chinese it also named a minute unit of measure; to say someone is not 苟 ("sloppy, careless") by even one 丝 is to say they never let up, not even on the smallest thing. The fixed form is usually traced to the Qing novel 《儒林外史》 (The Scholars) by Wu Jingzi, where it appears in praise of how meticulous an official is in carrying out his duties. Today it describes careful work of any kind: accounts, inspections, skilled handiwork.
