Lualaba (sounds like lullaby) is a province on the bottom of Congo. And Congo is a huge (compared to the other ones) country in the middle of Africa.
For our US visitors, Africa is a continent which is to the right and to the left of America at the bottom if counting from the South Pole.
So, what about Lualaba? I don’t know yet. But people are interested in it. Cool, init. Maybe that’s because the name sounds a bit interesting.
