This is a recent article done by the Guardian on a book that is coming out covering women who experienced foot binding. Warning: this article comes with many pictures for those who are sensitive to the issue. It's an interesting article that can also be used in lessons for those who mentioned covering foot binding as a possible lesson topic.
