A 19-year-old female backpacker from Shanghai, China named Ju Peng has been lambasted, after she posted an ad  to Chinese social media website Weibo, offering sex with a different man in every city she visits, so she could have funds for travelling the country.

Couchsurfing is quite common amongst travelers. A hospitality exchange and social networking website, Couchsurfing provides travelers a platform where they can find other members who will allow them to "surf" on couches by staying as a guest at a host's home. But in Peng's case, Elite Daily calls it  "bedsurfing."

Many critics are saying her "bedsurfing" ad is the same as prostitution and they are calling for the ad to be taken down, according to the Telegraph.

"If she was taking cash we'd all know what to call her. This is a disgusting way to carry on," said Weibo user Hsin Tao.

But as much as many people what Ju is doing is tantamount to prostitution, Peng said "bedsurfing" has already allowed her to travel all over eastern China. She defends her actions saying she simply wants to see the rest of the country through the ad.

"It is sort of like hitch hiking. It's nothing to be ashamed of," Ju added.

A student from Shanghai, Peng posted the online ad offering sex for travel on Weibo, which said the 19-year-old is seeking "temporary boyfriends."

Instead of paying lodging in China with money, she opted to pay with sex.

"They will fund my transport to their city and all my expenses while I am there and they need to be generous," she explained.

Every night, Peng said she is willing to stay at a different wealthy host. She gets a bed, while her host gets sex along with Peng for an arm candy. Apparently, she believes "bedsurfing" to be a foolproof way to find funds for her trips around the country.

Not only do the guys need to be rich, but Peng said they must be "good looking, under 30, taller than 1.75 metres and, of course, rich. In return, they get a whole night with me, my undivided attention, and a chance to show themselves off in the company of a truly beautiful girl."

According to Peng, "bedsurfing" has paved the way for her to travel all over eastern China, whilst offering her company to men. She thought of posting the ad since she doesn't have the funds to travel herself, according to the International Business Times.

Prostitution is the business of engaging in sexual relations in exchange for payment. Elite Daily calls the line between free love and sex trade in Peng's situation "blurry." In China, prostitution is widely accepted, though illegal.
