At this moment, the suona of folk music sounded, and Bai Le gave way. So far, folk music has won. They were brave in the movie. They try their best to do what they like, do what they want, and are not afraid of others' eyes. At that time, no one learned folk music and the school didn't want to teach it. They changed the world with their own small power. This is their enthusiasm when they were young. Finally, they succeeded.
