She is a 13 year old athlete who has won taekwondo titles both in Hunan and at national level. But in order to raise money for her father's kidney surgery, she has decided to sell her two gold medals.

Zeng Yalin is a student at Hunan Sports Vocational College. She is an ambitious girl with a very promising future. Like many other teenagers, she was rebellious, arrogant, and intractable. But now, because of her father's illness, she has became a completely different person. She works twice as hard as her fellow students, and always listens carefully to the teacher… She says she wants to give her father peace of mind.
