What's Carmen playing?

Carmen, the masterpiece of the famous French writer Merimee, was born 150 years ago. The composer Bicai adapted the novel into an opera. Carmen is a woman with a bad temper. She is beautiful, sexy, full of irresistible vitality and independent. She despises law, faith and society, and doesn't want any shackles to restrain her unrestrained mind, including love. Carmen and Don Jose are entangled in love. From the moment they met, they were attracted to each other and crazy about love. This love pushed Don Jose into darkness and violence until both of them were destroyed. Just as Bizet wrote her last lyrics: "Free Carmen was born and free Carmen will die".
