Lin Yi believes in being professional, even if it means standing around all day on high heels that are killing her feet, and dressed in a heavy lace gown on a mid-summer's day, sweating and itching in her costume.

This is the fourth year running that 23-year-old Lin has taken part in China Joy.

Although it was 35 degrees outside and she was standing eight hours every day during the four-day show, Lin says she was quite happy with her job, which pays her 2,000 yuan ($323) a day.

That sum should be kept a secret, Lin says, as the other girls in the same booth were getting just 1,200 yuan a day. An average China Joy show girl gets paid about 500 yuan a day.

But then, not all of them are as popular as Lin.

Two days before the gaming expo, there was a competition "to find the most gorgeous show girl" on WeChat, and Lin came in second out of the list of 50,

"The salary was based on the popularity of each show girl. As I have a larger number of followers on Sina Weibo and I'm better known among online gamers, it was totally fair to pay me a little more," she says with confidence.
