A free-of-charge group purchase of Vietnamese girls as brides on a group-buying website has attracted nearly 15,000 Chinese single men who want to register and try their luck.

The generous offer said it will cover the expense of a trip to Vietnam and help a single Chinese man find his true love on the upcoming Singles Day, which falls on Nov 11. Most of the Vietnamese brides are white collar workers who do not mind cash gifts, as many Chinese do, according to the website.
