It is normal to be at a loss when in a foreign land so a tourist usually asks for information. The best bet is a cop in uniform who can readily give you the correct information you need. However, there are times that you have to rely on the first person you see especially when you are in a hurry. But sometimes you need to be discerning especially when the person would give you added information. When we were in Beijing and walking towards the Tiananmen Square, there were many people walking. We asked one guy if we were on the right path, he said yes and then he offered us a short cut. The square was just straight ahead so what shortcut was he talking about? And he clarified that it is a hassle to pass by the checkpoints. So we went with him on a detour and landed in an art gallery - he is an artist and trying to sell his art works. That means we were fooled by him in going to a wrong direction. Naturally we didn't buy and then we walked back to where we were before.
