In The Zombie Shadows Chapter 102

Blue Star has twelve districts, and Jake Qi's territory is in district eleven. Apart from the territory, he currently only moves between the 8th and 9th districts, and rarely even sets foot in the 12th district when he traveled through.

For example, the desert in District 5, because it is close to District 8, I saw it twice during the flight. If you have the chance, you can check it out. As for the third area where zombies live, I have only heard about it from other people's mouths, let alone set foot in it, and have never even glanced at it.
