Dong Mingzhu, one of China’s richest and most powerful women, has reportedly dropped hints suggesting that she wants her 22-year-old secretary to be her successor as president of Gree Electric. The hint: Dong, 65, dropped the clue during a company event, jokingly telling investors and reporters that she was teaching her newly promoted secretary, Meng Yutong, to follow in her footsteps, according to Business Insider. “I hope she can stay by my side," Dong, known as China’s “Iron Lady” for her strict work ethic, said as she introduced Meng on stage.
