All eyes will descend on Gangwon, South Korea on Friday as the fourth Youth Winter Olympic Games begins with a stunning opening ceremony before 13 days of intense competition. One athlete who knows all about success at these Games is China's Eileen Gu who rose to global prominence with a stunning performance in the big air freestyle skiing competition in Lausanne four years ago. Gu then followed that up by delivering a sensational double gold display two years later in Beijing. Speaking to CNN's Amanda Davies, the 20-year-old sensation began by reflecting on the transformative nature that the Games can have on athletes.
