For my own answer :
As for you know different countries like philippines have music of it's own well as for you,China music always brought messages or maybe can be use in a traditional way like their belief in gods they lend a music for some blessing from their oh-so-called gods or maybe with music they can live happily .

p.s 
    That's the best that i can do don't research much about china i just answer what my opinion is ... :)
