In the fifth and final episode of our Bridge Builders Season 3, we meet Stuart Wiggin, a British vlogger who has changed people's views of China. Now more widely known to the Chinese as Situ Jianguo, Wiggin arrived in China in 2007, intending to stay for two years to learn the language. A decade and a half later, he's still here, and learning more than just the language. Thousands of miles from his British birthplace, he travels around China making videos to create a picture of his adopted homeland, for an ever-growing audience.
