This morning I took a cab and, thanks to intense road construction, walked the last five blocks, out to Beijing’s hopping Wudaokou district, home to more techie types than anywhere else I’ve seen in Beijing. Entering through a cozy bookstore as it opened for the day, I climbed a flight of stairs up to Lush, an international student hangout—with pancakes and great coffee, at last—to meet Calvin Chin, the guy behind the Web startup Qifang.cn.
