In order to change the monotony and rigidity of books in font, some booksellers put some famous manuscripts on the basis of retaining their calligraphy style, and wrote down samples to engrave books in the first edition. This kind of engraving has existed in all previous dynasties since the Tang and Song Dynasties, but few have been preserved. For example, Banqiao Collection, a collection written by Zheng Banqiao, a famous painter in Qing Dynasty, is not only a representative of printmaking, but also has its unique artistic characteristics.
