一诺千金yī nuò qiān jīna promise worth a thousand pieces of gold—a promise that can be counted on;a solemn promise
❍ 曹丘至，即揖季布曰：“楚人谚曰‘得黄金百斤，不如得季布一诺’，足下何以得此声于梁楚间哉？ ……” (《史记·季节栾布列传》2731)When Cao Qiu appeared he gave only a slight bow and said to Ji Bu, “People in Chu have a saying that'a hundred catties of pure gold are not as good as one of Ji Bu’s promises.’ I wonder how you have managed to get such a reputation in this region of Liang and Chu? …” 一诺千金yī nuò qiān jīn诺：许诺。一许诺下来就价值千金。比喻说话算数，讲信用。a promise that will be kept, a promise worth a thousand piece of gold, be as good as one’s word |
