Blair Sugarman loved studying language from a very young age. He majored in Chinese and Russian studies at Edinburgh University, and went to the Chinese city of Dalian in 2009. Language learning opened a door to a life on the other side of the planet. He moved to China, started a business, and became a well-known face on TV. "One of the things that the show taught me about building bridges between cultures was that you have to keep an open mind," he says. Learn more about his story in the last episode of Season 4 of The Bridge Builders.
