In the competition between western music and folk music in the film, the guzheng came out first, and then a harp opposite followed the erhu of folk music. Zhongruan came out, so did the opposite violin, and the dulcimer joined the battlefield. The two sides are neck and neck, and the atmosphere is anxious. 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. They made students who studied western music change their views on folk music and let more people know about folk music. They represent that I dare not dream at that age and do it myself.
