Beijing is one of the last ambassadors of an ancient culture that has been mesmerizing mortals seeking to understand this world for thousands of years. The Chinese capital’s 16,800 square kilometers are home to over 17 million inhabitants, and its multilane highways accommodate over two million cars each day. As a first-time visitor, one might be overwhelmed by the incomprehensibility of this city, which seems to run on endlessly; Beijing appears to have neither an end nor a beginning. But that should not trick any visitors: the city’s perfect square base, built in the fifteenth century, is arranged deliberately, so that everything has its perfect place. Millions of workers rush through this meticulously set system by their bicycles, tricycles, mopeds, cars, vans or even by foot, all crossing at the same intersection.
