Using the Sun to navigate...
In Canada (for example, any northern latitude), the Sun is low enough that it gives a good hint about the direction towards South. It's a natural guidepost.
I was in Taipei once (during summer), and the Sun was as near as makes no difference, directly overhead during the middle of the day. Useless for navigation. Combined with the Chinese signs and symmetrical bowl-shaped topography, forget it.
