1. The two versions of the book cover adopt different designs.
2. The crowdfunding version has specially designed the cover and inner cover, which is more exquisite and beautiful.
3. The crowdfunding version will adopt the binding method of sewing thread (that is, the back of the book is bound in series and then bonded), and the paperback version will only adopt the binding method of bonding (that is, the back of the book is bonded), so that the book after thread binding will be stronger and can be stored for a long time.
4. The outer cover and the inner cover of the crowdfunding version will be bronzed, and the paperback version will only be color printed with coated paper.
5. The crowdfunding version is a specific version and only provides crowdfunding. After crowdfunding, it will be printed in whole numbers. After crowdfunding delivery, the remaining copies may be sold at a higher price than crowdfunding in the official online store.
