It has come to my attention that the 7s deluxe hardcover edition comes with a map. I might have to make a proper post on this later but-- just as a quick thing: the map in the deluxe edition is neither official nor accurate, and should not be used for meta purposes!
There are many, many issues with it, not in the least the fact that Tian Yi Temple is surrounded by Cang Qiong Mountain's twelve peaks, and the fact that the demon world and the human world are portrayed as being on the same plane of existence (when, in fact, they are separate and can be overlaid onto one another re: merging the realms), and, while there is no clear scale (which is an issue in itself), it almost looks as though CQM takes up the area of an entire province or more.
