Origin Story
唐代诗人杜甫在《戏为六绝句》中写道：“王杨卢骆当时体，轻薄为文哂未休。尔曹身与名俱灭，不废江河万古流。”诗中感叹那些轻浮的文人作品很快就会被遗忘，而真正优秀的文学作品却能像江河一样奔流不息，永远流传下去。这首诗也成为了“不废江河”这个成语的来源。传说中，大禹治水，三过家门而不入，最终完成了治水的大业，他的功绩像江河一样永世长流，后人便用“不废江河”来赞扬那些流芳百世的伟业。
The Tang Dynasty poet Du Fu wrote in his poem "Playing with Six Quatrains": "Wang Yang Lu Luo’s style at the time, frivolous writing is still laughed at. You and your name will perish together, the great rivers will flow forever." The poem laments that the frivolous works of the literati of that time will soon be forgotten, while truly excellent literary works will continue to flow like rivers and be passed down forever. This poem also became the source of the idiom "Bu Fei Jiang He." Legend has it that during the Great Yu flood control, he passed his home three times without entering, finally completing the great undertaking of flood control; his achievements will flow forever like rivers. Later, people used "Bu Fei Jiang He" to praise those eternally famous achievements.
