Sorry for so many questions. In your reply, you gave some explanations. Some places you mentioned, I do not know why and the reason. From the website, I can not search much information about the page flip and copy. 

I have all these questions,  because I want to know why and this  is a learning process. 

Whether the essay you write is shared? If it is open, can you send the link?
