We still think of Silicon Valley as the world's technology hub, but China's quickly catching up. For one, consider this stat: China has created as many billion-dollar startups this year as the U.S. This week, Bloomberg Technology's Peter Elstrom and David Ramli travel to Shanghai to visit Colin Huang, the man behind the latest business to join this rarefied club of unicorns. Huang recounts his humble origins in Hangzhou and the various turning points in his life that took him to where he is today, at the center of China's bustling tech scene. At 37, now leading his fourth startup, Huang's just getting started.
