Zuo Si, a famous poet in the Western Jin Dynasty in China, spent ten years writing the famous Sandu Fu. In order to write Sandu Fu well, whether eating or sleeping, he is conceiving the language, ideological material and artistic realm of this Fu.

In order to record his sudden inspiration in time, whenever and wherever he thinks of any good sentence, he always takes a pen and paper with him and writes it down immediately.

Everything comes to him who waits, and every day is worth it. Ten years of cold and heat have passed, and Zuo Si has finally finished his "Sandu Fu", which is famous all over the world and spread through the ages. Sandu Fu is rich in language and fluent in writing, and has made great artistic achievements in materials and forms.

Once the article was published, Luoyang was a sensation and everyone rushed to reprint it. Because this article is long, writing with a brush also consumes paper. Of course, the most important thing is that too many people plagiarize. All of a sudden, the supply of paper in Luoyang became in short supply, and the price of paper soared. This is the origin of the famous idiom "Luoyang paper is expensive", which is really an extremely elegant event in the ancient literary world of China.

It took Zuo Si ten years to write an article that will make him immortal, and it is said that some young people can write a novel in a week now, which is really remarkable. The so-called "one second on stage, ten years off stage", any successful person has paid unimaginable hardships to realize his life and social value.
