Shanghai is a city of two faces. It is home to some of the world’s tallest skyscrapers, miles of luxury goods shops, and scores of trendy bars and restaurants. But look just beyond the main streets and you’ll find narrow alleyways packed with traditional lane houses, where laundry billows from bamboo poles, and local communities are alive and well.Shanghai has always been China’s most Westernized city. In its heyday, Shanghai had the best nightlife, the greatest architecture, and the strongest business in Asia. Nearly a century later, after extreme tumult and political upheaval, it’s back on top.Shanghai’s charm lies not in a list of must-see sites, but in quiet, tree-lined streets, the Bund’s majestic colonial buildings, sweet boutiques, and a dizzying array of places to eat and drink, from literal hole-in-the-walls to celebrity chef restaurants.Today, Shanghai has nearly 24 million people, the skyscrapers keep getting taller, the metro keeps getting longer, and the historical buildings continue to evade the wrecking ball. For how much longer is anyone’s guess.
