Ever wanted to see how your legs compare to Taylor Swift's? Social media users from China certainly do.

A picture of a woman who's identified as the pop star crossing her legs over three people has triggered envy in the country and prompted many to copy the pose to show off their long pins.

The 'how many people can your legs cross?' call-out follows the 'belly button challenge' and 'collarbones craze' as the latest trending topic to put people's figures to the test, reported the People's Daily Online.

Challenge accepted: Chinese women have been posting photos on social media of their attempts at the craze

Hot: The trend started earlier this week and has already become a big hit with challengers in China

Working it: Other tests include women holding coins on their collar bones and the belly button challenge

New craze: The post challenges people to find out how many people their legs can spread across

The trend sprouted when Kris Wu, 24, a Chinese actor and pop-star, sent Weibo users wild when he posted a photo in which his legs take up a whole sofa.

Over 42 million users saw the image on the site, which is the Chinese equivalent of Twitter, since it was put up on Sunday.

However, the craze really kicked off after a picture of a woman identified as Taylor Swift emerged in which she showed off her leggy figure by crossing her limbs over three people.

The innovative photo inspired fans to imitate the pose by seeing how many people they could spread their legs over.

So far, the original topic post has amassed 250,000 clicks since it was put up on Tuesday.

Testing the length of your legs is the newest challenge in a long line of 'figure-testing' trends that are taking China by storm.

Other social media tests have included seeing how many coins women can hold with their collarbones and the belly button challenge.

The belly button challenge involves people posting selfies of whether they can touch their belly buttons by reaching around their back.

As in many countries, long, skinny legs are seen as highly desirable in China.

This was shown earlier this month when Chinese model, Dong Lei, gained recognition for her incredibly long legs, which measure 45 inches - the same height as a seven-year-old child.

Dong first gained fame after appearing on the TV show, 'Supermodel' and earned herself the nickname 'Tui Tui,' which means long legs.
