Teachers on SexyMandarin are hired based on having good communication skills and how attractive they are.

There are no academic prerequisites at the moment.

A SexyMandarin teacher in Singapore told MyPaper last week she earns $30 an hour.

The New Paper on Sunday understands that teachers are paid extra for the private and group classes they conduct with paying subscribers.

These are just a few of the more established teachers in the school.

She says: "People say what they want to say. If you call a girl in revealing clothes 'slutty', then half of the fashion industry on this planet is slutty. I do not think my job is slutty at all. I am a beautiful, confident woman. I love my body and love being sexy."

She says: "My favourite role is the sexy nurse. I believe many guys fantasise about being treated by a sexy nurse. I enjoy role-playing and trying on all kinds of costumes and lingerie. But some fans send me annoying and flirtatious messages that freak me out a bit. I believe that I am an educator, just that I make it more fun.
