Beethoven-a famous German composer and a world-famous music master. He loved music all his life and was engaged in music creation all his life. But just as his career was at its climax, disaster befell him-he was deaf! This is undoubtedly a bolt from the blue for a musician. You know, listening is so important to a musician! For ordinary people, in this situation, they will definitely be devastated and lose the courage to live. But Beethoven was a great man. He didn't give up. He defeated the devil of fate with his firm belief and indomitable spirit. He finally succeeded. He has succeeded since he wrote the Ninth Symphony. It is precisely because of this success that Beethoven's life bloomed with dazzling light.
