Because of China's one child policy to control its ever expanding population - now numbering 1.3 billion people - there has been a lopsided explosion of young boys. It's a cavernous gender gap that is unprecedented worldwide. The ratio is up to 130 boys to every one hundred girls in some areas of China.
Traditional preferences for a son influence many women to abort their baby if an early term sonogram shows it's a girl.
In the next 20 years, it's estimated that 30 million Chinese men won't be able to find wives.
