Maybe you checked the episode online before, but you couldn't find it. The online versions are all The Yellow River Cantata's Turkish March, Rock on the New Long March, The Same Moonlight, Flower Girl, Leaving by Jet, Running with Bulls? "Broad Sky" and "The Story of Time"

However, when Cheng and Su Mei met in the library (14:5 1 sec), the episodes were Joe Hisaishi and Life Carousel. After listening, don't just listen to the front, the front is the piano, and the middle should be what you want.
