My Chinese friend (25+) wanted to get married, so he had to choose how to spend the small amount of social time a PhD afforded. He could either try the American system which involves a lot of time at the gym and years of soul searching, not to mention racial bias. Obviously, he choose the Chinese way which involves recommendations from friends and more traditional views, that accepts that a male might spend 10 hours a day working. The guy went from virgin to hitched in a year and a half, and can still keep up high work productivity.
