My 34-year-old work colleague was beaming with joy, giving away sweets to everybody. Xie Fang was finally getting married and no longer felt a sheng nu (left behind woman).

I am told that the age of 28 is a most desirable age for matrimony, and when a woman reaches this time (men are given a few extra years' grace), a NASA-style countdown begins.

Xie could hear the clock ticking loudly for years so I understand her sweet gratitude. But as I was chewing on these lollies and minding that question was launched at me.
