There is no such person. At the age of 11, he was studying in Yen-j, a junior high school in San Francisco. He heard a miracle that changed him from the music teacher's fingertips ... It was a jazz music with a speed of over 351, far exceeding the speed of ordinary pop music fast songs of about 151. The piano keys were like a rainstorm, and one key hit Yen-j's heart crazily. Every key is like a wake-up call, a sign of a miracle arrival. How can there be such a cool voice in the world? Yen-j, who had always rejected his mother's proposal to learn piano, took the initiative to learn jazz piano and embarked on the music road. This piece of music is called "Donna Lee", written by jazz legend Charlie Parker, Yen-j, who is 11 years old, and began to look for all the historical sources of jazz, looking for stories about Donna Lee, like tracing back to his innate sense of music. To pay tribute to Charlie Parker, Yen-j wrote Donna Lee in Chinese and told the story of a girl who was moved by music and left home to learn jazz.
