Has it been that long? What you didn't know about this place.

I've lived here for the past 12 years. I'm going to tell you a bit about this place, you have no idea how wrong I was about this country before I moved here.  Your idea about this country may also be different.  Do you want to know which country I'm referring to? I'll give you a hint. Gunpowder was invented here. Still cannot guess? Have a listen & find out.
