A thread-bound book is a traditional Chinese book format, usually made of paper and thread. The following are the basic steps to make a thread-bound book: 1. Choose a paper: Choose a soft, easy to tear paper that is of a suitable size to accommodate the contents of the thread-bound book. Cutting paper: Cutting paper into a suitable shape, usually 16 inches long and 16 inches wide, about 25 inches thick. 3. Make the cover: Draw the title, author, publication date, and other information on the paper and sew them together using a thread-binding machine or hand thread. 4. Sewing the cover: Sewing the paper and sewing machine thread or handmade thread together to fix the whole book. 5. Fill the spine: fill in the spine paper and use the thread to fix the spine. 6. Cover: Make the cover and sew the two together with thread. 7. Book Assembly: Assembly the chapters of the book in order and fix the cover and cover together. [8. Retouch: Retouch the book includes checking the order and content of the pages, as well as adjusting the overall shape of the book.] Making a thread-bound book required patience and care. It required mastering the skills of the thread-bound book machine and a certain degree of hand-made ability. These steps required a certain amount of time and effort, but the thread-bound book produced had a unique cultural and historical value.
