Nine years ago, Tom Carter traveled from San Francisco to China, responding to a job posting that turned out to be a scam. He managed to find another job as a teacher, and saved enough money to embark on a 56,000 km trip through all of China's 33 provinces that lasted two years. Carrying a camera – just a a 4-megapixel point-and-shoot – Carter captured some amazing images of the widely varying landscape, people, and architecture across the nation.
