During the Spring and Autumn Period, there was a man named Boya who studied guqin with Mr. Cheng Lian. He mastered all kinds of playing skills, but the teacher felt that when he played, he often didn't understand deeply. He just played the notes, which lacked a little charm and could not resonate with the audience. The teacher wants to train him to be a real artist. One day, Mr. Cheng Lian said to Boya, "My teacher Fang Zichun lives in the East China Sea. He can. Let him tell you about it, which can greatly improve your artistic level. " So the master and the apprentice prepared dry food and set off by boat. After arriving at Penglai Mountain in the East China Sea, Mr. Cheng Lian said to Boya, "You stay here and practice the piano, and I'll find the master." Then he gradually shook it away. Ten days later, Mr. Cheng Lian didn't come back. Boya waited anxiously on the island and raised his eyes after tuning the piano every day. From time to time came the sound of birds singing and flying. These interesting and strange scenes made him feel relaxed like a dream, and he felt that his taste was much higher. Boya has creative passion and wants to compose his own feelings, so he set up a piano, poured his passion into the strings and wrote a song "Mountains and Rivers" in one go. Not long after, Mr. Cheng Lian came back rocking the boat. Boya suddenly realized that the sound of waves and birds are the best teachers. Since then, Boya has accumulated experience in life and art, and eventually became the piano master all over the world.
