A married man from the eastern Chinese province of Anhui was looking for some online hanky-panky.

So the man, identified by the Market Star Dailyas a forty-something named Mr. Zhang, reached for his mobile phone and clicked on “Shake”, a location-based social plug-in service provided by Weixin (Chinese for WeChat). Zhang began chatting, and wound up setting up a rendez-vous with a 20-year-old woman at a local hotel, all the while claiming to be just over 30, rich and single.

But when Zhang got to the hotel, the mystery woman turned out to be his own daughter. Moments later, his wife, Li, came storming through the door — she had been tailing him after growing suspicious about how often he was checking his phone.

Market Star Daily reports that police were eventually called in to keep this awkward family reunion from getting even uglier.
