差以毫厘,谬以千里 is a Chinese idiom (chengyu) meaning “a minimal error or slight deviation at the beginning can lead to a significant divergence or serious mistake in the outcome”. Literally, “A difference of a hair's breadth leads to an error of a thousand li”.
During the Western Han Dynasty, Zhao Chunguo was ordered by Emperor Xuan of Han to suppress a rebellion in the northwestern regions. Observing that the rebel forces were disunited, he adopted a strategy of conciliation, which led most of the rebels to surrender.
However, Emperor Xuan then ordered him to launch a military attack, which resulted in an unfavorable outcome.
Later, when he collected military provisions according to the emperor's command, it inadvertently triggered another rebellion. Zhao Chunguo sighed and remarked, "Indeed, a miss by a hair's breadth can lead to a divergence of a thousand li!"
