Title: Initial removal of english books from chinese(zh) books list.

Removal decisions were made comparing it with the english(en) books list; itens with the exact same link were removed.
Further removal may need a more careful consideration, since for some reason these book's titles were translated to chinese in the *zh* list. Also, I'm tired for today.

Added 3 chinese(zh) books.
