...Although the aura of Zheng's expeditions may somehow bolster China's budding soft power, it's unclear what lasting impact the visiting fleets had on medieval Africa.

"When you go through what I've gone through, you come to appreciate who matters and what and why," he says, referring to his family. "But you also lose a bit of the edge that leads you to tilt at windmills. Maybe you might call that ambition. Silda used to say, 'Being right isn't the only thing.'
