A 19-year-old backpacker from China has been lambasted, after she posted an ad offering to have sex with a different man in every city she visits, to fund her travels.

Ju Peng, a student from Shanghai, posted the online ad on Weibo, in which she says she is seeking "temporary boyfriends."

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

She added that 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."

Peng said that she has already travelled all over eastern China by offering the pleasure of her company to men in exchange for their generous hospitality and now plans to see the rest of the country in the same way, as she does not have enough money to fund her trip herself.

Critics have described her conduct as tantamount to prostitution and have called for the ad to be removed.

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

Defending her actions Peng said: "It is sort of like hitch-hiking. It's nothing to be ashamed of'."
