To some Americans, Iowa, a rural state in the middle of the US, is dismissively thought of as "fly-over country".
Yet the Hawkeye state is well-known in China. Chinese President Xi Jinping has visited twice - before he took office in 2012, and in an earlier stay as a low-level local official on a 1985 trip to study farming technology.
Iowa was once again a destination for Chinese visitors last week, though those who descended upon the state were not there to study soybeans, but democracy in America.
Amid its chaos, young "democracy tourists" learnt first-hand that it can be a messy way to govern.
