In ancient times, people who used block printing to print books needed not only calligraphy skills, but also skillful knife skills to carve the corners and verve of calligraphy and painting. Book engravers need to learn skills such as engraving, inking, printing and binding, which are all done by hand and need a solid professional foundation.
The engravers in Song Dynasty cherished their own creations. They often engrave their names, hall numbers, or store names, engraving dates and other matters on books, which should be the earliest copyright.
The "Jinxi Book", which enjoys a high reputation in the collection of ancient books, refers to the woodcut of Wan Hu in Jinxi County. The old version of Ci Yuan recorded that "both men and women in Wan Hu in the west of Shanxi are good at lettering and printing books". "Paper is untidy in the bay" and "It is not safe to publish books in Jiangxi". The prosperity of woodcut book industry won Jinxi the reputation of "Jiangnan Book Town" and created the title of "Jiangxi Edition".
