The closure of the Eastern Tibetan border forces the Pyle brothers to travel by plane reconnecting with their bikes in Shangri-La. From here they head to Guizhou province, but the improvement of the road tarmac and heavy rain make the road travel incredibly dangerous and Colin smashes his bike into a tree. Back on the road with new street tyres, Ryan and Colin make their way through the mystical karst landscape of Guilin and on to the manufacturing heartland of China before striking out for Shanghai, via Putoushan island and the Yangshan Port, the biggest and busiest port in the world.
