"Marrying the right man is our biggest dream," one young Chinese girl's song goes. But while the cars and houses are coming easily to China's successful women, marrying their dream man isn't. Despite a gender gap of 118 men for every 100 women, China's conservative dictum is that a woman should not be too independent and that over 28 she's labelled 'leftover'. It means that most successful women struggle to get a date and with a third of China's millionaires now female an increasing number of China's women are prioritising their work life. The result is "200 million singles in China and it keeps growing...", as Johnny Du, the CEO of one of China's top internet dating sites, explains. According to Johnny Du the women also set the bar too high. "Woman are really picky; they want the man to be very rich, young, handsome, educated...". Some parents have become so desperate they are taking details of their single children around "marriage markets". As the ambitions of the West meet the traditions of the East, it's a dangerous cultural hang-up that's causing a social time-bomb.
