Open the book mall page, display the list of e-books, and click the plus sign in the red box.
The method of adding books will be displayed, because the e-book is in the palm, so you can choose local books.
Inside, you will see your latest downloaded e-book, HTML 5 from entry to mastery.
Check the radio box behind the ebook. When checked, "Add Bookshelf" (1) will be displayed.
Click Add Bookshelf (1), and a warm reminder will appear. If you don't import directory grouping information, confirm it directly.
Click OK.
