So the Chinese seem to like using cutsie music for all sorts of things. Like the garbage truck. I heard some music and immediately thought "ice cream man," but was corrected. Yes, the garbage truck runs ice cream man music the entire time it is doing it's rounds. Imagine being a garbage man.
Also, there is cute music instead of a bell whenever class starts, break begins, or class ends. Again, it is absurdly childish music, and it goes on for about 15 seconds each time.
I guess Asians are generally more excited about cute things. There's nothing wrong with sleeping with stuffed animals when you're in college. There's nothing wrong with wearing shirts with Hello Kitty on them, or with guys having phone tassles with cartoon characters. It's actually quite refreshing. Oh fer cute!
