According to a recent study by the Chinese Academy of Social Sciences, 24 million Chinese men will be unable to find wives by 2020 because of the country's gender imbalance. Before the mass migration from the villages to the cities, young men could rely on their parents to find them a wife. Now many of those single women live in the cities, working in factories. They only see their parents during the spring festival so the chances of finding a wife are limited. It's a particular challenge for men with low income, who don't own their own apartment or who don't have a good job. In some parts of rural China there are several communities with so many single men they've been labelled 'bachelor villages'

The trend has led to a growth in internet dating while at the high end, rich men join 'single entrepreneur' clubs that run competitions to find them that someone special.

Lucy Ash reports from China on the ways in which both parents and the single men are attempting to make the perfect catch.
