As a cosmopolitan city teeming with more than 20million people, Beijing is used to seeing some strange things.

But despite the eclectic characters that make up the bustling capital, this is a sight that will shock even the most hardened citizen.

A naked man was seen dashing through the city carrying a life-sized inflatable doll – hotly pursued by a nude woman.

Run for your life! For some unknown reason, the man dashes through the streets naked with a sex doll, while his female companion follows

Hold on tight! The man leaps across the road – and is now the subject of intense scrutiny from Chinese bloggers

Bloggers are baffled after the naked trio were caught on camera streaking through the streets – with the grimace on the man’s face plain to see, as he clutches his blow-up companion.

Some have suggested it’s a romantic game gone terribly wrong, while others mused that it was an art project.

On Shanghaiist, a confused citizen wrote that the pictures are sweeping across Chinese social media, and people are trying to piece together what happened and the identity of the daring duo.

They wrote: ‘Is it an art project? A sex game gone wrong? A woman jilted by a silicone mistress?’

The man seems more concerned about his inflatable friend than the woman dashing behind him

The naked dash happened at around 3am in the Wangjing neighbourhood in Beijing.

The South China Morning Post said that speculation was rife about whether it was a publicity stunt.

‘Is this a real-life Temple Run?’ wrote a blogger, referring to the game where players become an explorer who steals an idol from a temple and flees from monsters chasing it.

The people of Beijing are no stranger to the odd nude streak.

In February people took part in the Naked Running competition at Olympic Forest Park.

Around 300 participants took part in the annual 3.5 km Undie Run, which promoted environmentally-friendly lifestyles.

Wanging is a busy residential area in the northeast of Beijing, China.

‘Wangjing’ translates into English as ‘View of Beijing’.
