A year ago, Zhang was considering quitting the entertainment industry after a string of failures.

However, her schedule now only allows her to do an interview during lunch just before setting off for the airport.

Her career has seen a Cinderella-like transformation thanks to her role in a 36-episode online comedy, Go Princess Go, made by online video company LeTV that premiered in December.

"My life was reshaped after I accepted that what I was doing was wrong and opted to try something different," the 26-year-old says.

Go Princess Go is about a playboy's transgender time travel to become a princess and later the empress dowager through conspiracies in imperial harems.

Each episode is 30 minutes.
