I was going to meet some anthropologists of religion near the new campus of East China Normal University, which is at the bottom of the third leaf on the bottom. I took the subway - line 5, my first time - to the nearest stop and looked for a bus along the main road eastward 剑川路. Down there, though, the buses don't have numbers but names and I hadn't noted which one I should take. Still, I assumed that most of the buses would be continuing on that main road, right? No such luck! When a bus finally pulled up to a stop I got in only to find it turn right and then on to the elevated highway south! Next stop ten minutes later in a sleepy country town! Thankfully a young man who spoke English helped me find a taxi - another ten minutes - and I was able to return to the charted world. I was relieved; the anthropologists were amused.
