I never had to worry about finding my way in Beijing before. It's not because I knew Beijing well, but because I had a local guide.
This time, I am on my own (though I can email and call for help). So, how can I NOT get lost?
I had no sense of directions until I had to drive. A friend majored in geology taught me this trick: Put yourself on the map, so you always know which direction you are going. It worked like a charm when I was in South Florida, in D.C., and in Seattle. After we have moved to Honolulu, I had to learn one more thing: toward the ocean or toward the mountain. Yes, when you are in Hawaii, that's how the locals will give you the direction.
