Since when Hongkong Triad call their boss: "Godfather" ???
I think you're reaching a bit hard.
I'd say your Godfather and Breaking Bad references are coincidental.
And what zoo? Did I miss something? There were monkeys around, sure. There are actually monkeys in Hong Kong.
As for Triads calling their boss "Godfather" I don't know, but it's possible this was not a literal translation.
