Why not number the houses? On the one hand, we expect aliens to do things differently. On the other hand, numbering seems the simplest system. But, in Britain, we do not number the streets. We do not have Fifth Avenues. (Well, we might have one somewhere.)
A guy who had traveled in China said, "When you go to a bus station, you expect to see signs informing you which bus goes where, don't you? In China, you just see a lot of buses drawn up and a lot of people milling about." When asked, "How do Chinese people know which is their bus?," he replied, "Eventually someone tells you." It sounds like trying to find our coach after a big demonstration - except that we should remember the coach company and the registration number... Life has become so much easier with mobile phones.
So, if China is different, then Merseia should be more different - in minor and unpredictable ways like how to find where you are going.
