A word about Ka Kui Wong, see what it means.

I don't think so. The theme of Jiaju music is not the love between men and women, but the pursuit of ideals, freedom and freedom. Ka Ju's words are telling us that the music scene in Hong Kong has been commercialized, full of money transactions, and music has lost its meaning. So he dreamed of seeking an idealized space, the true meaning of music and the bondage of dating commercialization. The "openness" here may mean that there is no distractions, no commercialization, and everyone only appreciates pure music!
