touchNbook - New way to touch a book description

Cartoons and novels can be fully enjoyed through eBooks that you can only view.
However, studying with an eBook that only views learning/educational content such as math books or English books is as difficult and ineffective as learning'biking' or'swimming' with only books.
Write English words or math, listen to the pronunciation of a native speaker, and experience a three-dimensional study of watching video lectures on the page you are viewing through touchNbook.
