📖 Meaning
To smear or dab colors recklessly. 'Nie' means to dye or blacken, and 'zao' means black. The idiom originally describes someone obsessively working with dyes and colors without rest, and by extension refers to aimless or compulsive activity.
📜 Origin Story
The phrase comes from the Tang dynasty work 'Youyang Zazu Xuji' (Supplement to the Miscellany of Youyang Mountain) by Duan Chengshi. It tells of a certain Magistrate Yao who lived in Fenzhou. After a year, his two daughters became mentally dazed and disoriented, keeping lamps lit at night to sew, constantly dyeing blue and black without ever resting—yet no one ever saw what they actually produced.
💡 Example Usage
