     When I crossed a small road on my first day in Kolkata, I was surprised because I heard a bell-not a horn (喇叭),  It was a tiny man pulling a rickshaw, He stopped and picked up two children from the front door of their house and pulled them to school. For many people, the rickshaw in Kolkata has many advantages, When the traffic is bad, rickshaws find a way through the traffic. If your miss your bus and there aren't any taxis, you can always find a rickshaw in Kolkata. Rickshaws are from your house to the market and waits for you.
