The Chinese term for mutually beneficial relationships essential to success in the Middle Kingdom, tells the story of the juggernaut research lab that underpins Microsoft's relationship building in China. Unfurled through a gripping narrative that moves between Beijing and Microsoft headquarters in Redmond, WA, it follows the lab's emergence as a Mecca for Chinese computer-science talent - a place where 10,000 resumes arrive in a month, written exams are farmed out to 11 cities to screen applicants, and interns sleep on cots next to their cubicles. So far, the company has invested well over $100 million and hired more than 400 of China's best and brightest to turn the outpost into an important window on the future of computing and a training ground to uplift the state of Chinese computer science creating dramatic payoffs for both Microsoft and its host country that are helping the company overcome many of the challenges of China.
