What was a small market town 1,000 years ago has become a booming metropolis, the most populous in the world, in fact. Amid the motorbike-clogged traffic, ornate parks, shopping areas, and the artsy scene thrive, offering something for each of its 23 million inhabitants and tourists that come to take it in from all corners of the world.
