The company Zhang, 46, co-founded with husband Pan Shiyi, is now the largest commercial real estate developer in Beijing. (Her latest project is a Zaha Hadid-designed, 50,000 square meter complex called SOHO Galaxy.) SOHO isn't just riding China's coattails: Sales last year grew 132% to $2.8 billion -- far outpacing the growth rate of the Chinese economy.
