     It was a long process that involved creating a resume, submitting an online application (申请) and

attending a round of interviews. Naturally Tan Kaiyin, a 21-year-old student is excited when she was

selected, as more than 660, 000 people signed up to volunteer at the 16th Asian Games in Guangzhou,

but only less than 10 percent were finally chosen to work in the venues and wear the white and green

sport uniforms.

     Like in any major sporting event, volunteers play a vital role in assisting with operations and Tan's

function here is not any different. She is based at the Garden Hotel and is tasked with helping guests and

officials who have issues with their accreditation cards (注册卡). "I deal with guests from all over the

world, I have never met so many international people and it is very, very exciting to have this opportunity

to interact with them. They come to the office because they need to make a change in their accreditation

card and usually they are in a hurry, so we try our best to get it done quickly."

     She admits the first few days involved extremely long hours, however she likes the challenge as it

gives her an immense sense of satisfaction especially when an irate guest turns a frown into a smile and

says "thank you".

     Tan deals with people from different cultures and personalities and feels she has learned so much in

the past week, an experience that she would have never gotten if not for the Guangzhou Asian Games,

therefore she is very happy and grateful for being a part of this. She also has kind words for her

managers and fellow colleagues and says the hard work and positive atmosphere has bonded them into

a family. She enjoys her responsibilities so much that she is afraid of feeling lost when the Games finally

end on Nov. 27.

     However, she is aware of all the positive effects the Games have had on Guangzhou. From

improvements to air and water quality to better transportation and infrastructure in the city, but most

importantly to her is the fact that the Asian Games has placed Guangzhou prominently onto the world

map. This, she believes, will encourage people from all over the world to continue visiting her city, and

this in turn will give the residents of Guangzhou a fantastic opportunity to continue learning about different

cultures. The official Asian Games Volunteer Slogan is, "Together, we can make it better!" Indeed it

seems they can.
