在很久很久以前，有一个叫季布的人。
他是一个乐于助人、讲信用的人，他答应过别人的事情，一定会想办法做到。
所以，大家都很喜欢他，他的名声也越来越大。
有个叫曹丘生的楚国人，他喜欢用财物去结交有权势的官员，这样可以提高自己的地位。
有一天，他听说季布做了大官，就想要去见他。
于是，他去找窦长君帮忙介绍。
可是，窦长君告诉曹丘生，季布不喜欢他，让他不要去。
但是，曹丘生还是坚持要见季布，他就请求窦长君写一封介绍信。
窦长君虽然不愿意，但最后还是答应了。
曹丘生拿到介绍信后，立刻去拜访季布。
见到季布后，他深深地鞠了一躬，并且说：“我们楚国有句谚语：‘黄金百斤，不如得季布一诺。’你的名声之所以这么大，都是因为我帮你传扬出去的。我们都是一家人，为什么你一直都不肯见我呢？”
季布听了这句话，非常开心，他以贵宾之礼招待曹丘生。
曹丘生在季布那里住了几个月，离开的时候，季布还送给他一份丰厚的礼物。
曹丘生继续帮季布宣传，季布的名声也就越来越大。
后来，“一诺千金”这个成语，就是从“黄金百斤，不如得季布一诺”这句话演变而来的，用来形容一个人说话算数，信守承诺。
In ancient times, there was a man named Ji Bu.
He was a helpful and trustworthy person who always kept his promises. He would do whatever it took to fulfill what he had promised to others.
That's why everyone liked him, and his reputation grew bigger and bigger.
There was a Chu man named Cao Qiu Sheng who liked to use wealth to make friends with powerful officials so that he could raise his own status.
One day, he heard that Ji Bu had become an important official, so he wanted to meet him.
So, he went to Dou Chang Jun for help in introducing him.
But Dou Chang Jun told Cao Qiu Sheng that Ji Bu did not like him and advised him not to go.
However, Cao Qiu Sheng insisted on seeing Ji Bu, so he asked Dou Chang Jun to write a letter of introduction.
Although Dou Chang Jun was unwilling, he finally agreed.
After obtaining the letter of introduction, Cao Qiu Sheng immediately went to visit Ji Bu.
When he saw Ji Bu, he bowed deeply and said, 'In our Chu state, there is a saying: 'A hundred catties of gold are not as good as one promise from Ji Bu.' Your reputation has grown so big because I have helped spread it. We are all family, so why have you been unwilling to see me?'
Ji Bu was very happy when he heard this. He treated Cao Qiu Sheng as an honored guest.
Cao Qiu Sheng stayed with Ji Bu for several months. When he left, Ji Bu gave him a generous gift.
Cao Qiu Sheng continued to promote Ji Bu, and his reputation grew even more.
Later, the idiom 'A Promise of a Thousand Gold Pieces' came from the saying 'A hundred catties of gold are not as good as one promise from Ji Bu.' It is used to describe someone who keeps their word and honors their commitments.
