Opinion | Who are Beijing's naked 'sex doll' couple? Bizarre photograph goes viral

Is it art or madness?

A series of photographs which went viral on China’s social media this week show a naked man running across a street late at night.

The man is holding what looks like a sex doll and is closely followed by a woman who also appears to be naked.

The photos, which were apparently taken in Beijing, drew heated discussion and speculation online.

"Is this a real-life Temple Run?" wrote a blogger, referring to a popular game where a player takes on the role of an explorer attempting to steal an idol from a temple and outrun monsters chasing from behind.

"It must be some kind of publicity stunt," said another.
