From the left side of the screen, I live in the second house, which is the yellow house.When I go to the post office, usually I take my car. I drive in fornt of my hosue towards the post office. First of all,I make a right turn on the street, then left turn on the same street, and then take a left turn.I reached my destination.
Look at the map. Imagine you're at home and you want to go to the post office. Which way should you go?
