Origin Story
唐代诗人李白，少年时期就很有才华，但家境贫寒，不得不外出漂泊。一次，他来到一座大山脚下，抬头望去，只见山峰高耸入云，气势磅礴，山腰间云雾缭绕，若隐若现，山顶更是被云雾遮盖，难以窥见全貌。李白不禁感叹道：“这座山真雄伟壮观啊！可惜只能略见一斑，难以窥探其全貌。”后来，他凭借着自己的才华，终于名扬天下，也得以饱览祖国的大好河山，领略了无数奇峰异景。
Li Bai, a Tang Dynasty poet, was very talented from a young age, but his family was poor, so he had to wander.Once, he came to the foot of a large mountain, looked up and saw only the towering peaks, the majestic atmosphere, the mist in the middle of the mountain, which was sometimes visible and sometimes invisible, and the top of the mountain was covered by mist and difficult to see.Li Bai couldn't help but sigh: "This mountain is truly magnificent!Unfortunately, you can only see a small part of it, you cannot explore its entire appearance."Later, through his talent, he finally became famous and was able to admire the beautiful scenery of his country and admire countless strange and beautiful scenes.
