《唐摭言》里有个小故事:自居易初次到长安应举,因为没有名声,就拿着自己的诗作去拜谒老诗人顾况。顾况见他名为“居易”,就开玩笑说:“长安百物昂贵,居住下来很不容易。”等到读了《赋得古原草送别》中“野火烧不尽,春风吹又生”的诗句,不攀击节赞赏,又改口说:“能写出这样的诗句,就是居天下又有何难!” There is a small story in Tang Yan Yan: Since the first time he moved to Chang’an, he had to give up. Because there was no reputation, he took his poetry to visit the old poet. Gu Ju saw him as “Chang” and jokingly said: “Changan is expensive and it is not easy to live.” When he read “Farewell Ancient Grass Farewell”, “Wild fire is not exhausted, the spring breeze is born again.” The verses were not praised and praised, but they also changed their mouths and said: “The ability to write such verses is what makes it difficult to live in the world!”
