"I am so excited," she says.

She failed to win a volunteer spot in the third round of recruitment last year.

"But this year, I was recruited in the first round," she says.

"The conference gathers a lot of internet-industry elites. I read some of their stories. I may have the chance to meet them face to face," Wang says.

It is the second time for Jin Xianying to join the volunteer team.

Jin is in the same university as Wang and is a junior majoring in Chinese language and literature. The Jilin native from Northeast China can speak Korean and English.

She says her experience last year was "unexpected".

"Many people applied, so I followed," says Jin, who saw the recruiting announcement in a local online-chat group.

"I just wanted to give it a try. I didn't think I could pass all the tests."

But Jin had an advantage: She was the only applicant for the Korean-language service vacancy.

She worked as an one-on-one VIP service volunteer.

"Confidentiality is the prime requirement. The experience widened my vision. So I applied again this year without any hesitation."

This time, Jin had to compete with other applicants.

"More young people are willing to serve society and help others. So I had to do a lot of preparation."
