I traveled with a friend from south to north, starting in Guilin and passing through Yangshuo, Fenghuang, Changsha, Chengdu, Leshan, Xian, and finishing in Beijing. We traveled via a combination of foot, train, bus, taxi, motorcycle taxi, and airplane.
A short paragraph can hardly do my experience in China any justice, but it was an amazing trip where everything proved to be some sort of adventure. I was most impressed by the kindness of the people we met, who were often curious about us, asked for photos, and helped us along.
I spent quite a bit more time cycling through China on a later trip, here.
