"The Big Momma in question is Zhang Yin, a 49-year-old paper recycler who has just emerged not only as the richest entrepreneur in China, but also as the wealthiest self-made woman in the world. According to the Hurun Report rich list, Zhang, despite being almost unknown in the wider world, has suddenly arrived at the top of the list with a net worth of $3.4bn.
Zhang, who continues to hold a 72% stake, had some powerful champions who helped put her on the map, notes the FT. Three of Asia’s most influential businessmen, Cheng Yu-tung, Robert Kuok and Lee Shau-kee, snapped up some $20m worth of shares, leading to a stampede of interest in Nine Dragons: the shares have since rocketed by 165%."
