Jia Ling's new movie YOLO topped this year's Spring Festival box office. The movie tells the story of a jobless woman who becomes a (success) boxer after hard work. Through this movie, Jia wants (express) the central idea of "love yourself". That is also the reason the English name of the movie is You Only Live Once. To make the movie more inspiring, Jia first gained weight and then lost50kg to show a great change from the past. She brings us not only laughter but also positive energy.
