This idiom comes from History of Jin・The life of Zuo Si. Zou Si was a famous writer in the Western Jin Dynasty. Because of his serious attitude to writing and not concentrating on quantity, he could write excellent articles.
Capital of Qi Rhapsody, which took him one year to write, was an article about the capital of State of Qi. As the book coming out, Zuo Si displayed his remarkable talent on the literature.
Later he moved to live in the capital, Luoyang and was appointed to be "Zhu Shu Lang" (an official of writing books). Since then，Zuo Si concentrated all his attention on writing books.He began to write Three Capital Rhapsody (Three Capital refered to the capitals of the Three Kingdoms of Wei, Shu and Wu) describing the history, culture, people and customs of the three capitals.
Because he always thought about the plot of the book, he put pens, paper and ink everywhere in his house even in his bathroom, so as to write some useful words or sentences which he just thought out. After ten years' painstaking efforts, he finished Three Capital Rhapsody at last.
After it was published, it was highly praised by the leading literary figures of his time. The content of the bookandthewritingtechniquehadreachedthe unprecedented level, and the article skill was also very high. Soon it became so popular that almost all the high officials and the rich families tried to be the first to buy paper to copy it. It made paper in short supply and the price rose day by day.
From this comes the idiom "Luoyang Zhi Gui"――paper is dear in Luoyang.
Now we use it to praise good writings which are so excellent that they become fashionable for a while and are spread far and wide.
此语出自《晋书・左思传》。左思是西晋时期的文学家，由于他写作时特别认真，并不追求速度，所以写的文章质量比较高。
他曾经用一年时间写成一篇《齐都赋》，这是一篇有关齐国都城的著作。此书一出，使他在文学界崭露头角。
后来他到都城洛阳居住，被任命为著书郎。从此左思专心著书，开始写《三都赋》(三都指的是三国时期魏、蜀、吴三国的都城)。该书描述了三都的历史、文化和人民生活习惯等。
由于他时刻都想着这篇文章，所以在他家里，不管是书房，还是走廊、庭院内，甚至连厕所里都挂着纸和笔，不论何时只要想出好的词句，就记下来。这样他经过十年的刻苦努力才写成了这篇名著《三都赋》。
《三都赋》一问世，深受当时文学界的赞扬，无论是内容和写作技巧都达到了空前的水平，其艺术价值很高。所以当时都城洛阳城内一些有地位的贵族都争着买纸抄写阅读，文学爱好者也纷纷传抄。一度造成洛阳的纸张供不应求，价格很高。
由此引出“洛阳纸贵”这条成语。后用此典比喻和赞扬好的著作由于精彩动人而风行一时，广为流传。
