China’s Zhang Yin has become the richest woman of the world exceeding the enormous amounts of wealth of the likes of Oprah Winfrey and Harry Potter author J.K. Rowling. She is the founder of Nine Dragons Paper, which buys scrap paper from the US for use in China. 49 years old and still striving forward, Nine Dragons’ shares have almost tripled in value since they were listed on the Hong Kong stock exchange.

Zhang Yin managed to top the list with a whopping accumulated wealth of $3.4bn (£1.8bn).
