Is traditional handmade paper expensive? Why?

The word "Luoyang Paper Expensive" comes from the Biography of Jin Wenyuan's Zuo Si, and the sentences in it come from Zuo Si's Sandu Fu. He created a good book, and many people bought it and read it, which made the book expensive, and then the paper was expensive.

There is a saying in the Biography of Jin Shu Wen Yuan Zuo Si: "Therefore, luxury houses compete for biography, and Luoyang is also expensive." It means that nobles and giants spread words to each other, and Luoyang's paper is therefore expensive. Let's just say that the price of paper has risen for thousands of years. This sentence comes from Zuo Si Zhuan. Compared with Zuo Si, Zuo Si is a great man.

Zuo Si was rejected by his father when he was a child, but he didn't care about it. He was deeply influenced by Sidufu and Liang Jingfu, and was determined to write articles as excellent as them. It is said that Zuo Si collected a lot of information about history, geography, products, customs and human feelings in order to create Sandu Fu, and worked hard behind closed doors. It took ten years to write Sandu Fu.

Although he wrote a book, no one looked down on him, so he found a famous writer, Zhang Hua, who spoke highly of the book. Zuo Si also made a man named Huangfu Mi cross his eyes. After reading Sandu Fu, Huangfu Mi also spoke highly of it and wrote a preface. Zuo Si was very moved. So Zuo Si became so popular. His "Sandu Fu" became popular, as did those who sold books and papers.

This is the origin of the word "Luoyang paper is expensive", because a book by Zuo Si has also become expensive, and the chain effect brought by economic development cannot be underestimated. One industry drives the rapid development of another industry and is closely linked.
