Great wall

Today I went on a 10 Km walk along the Great wall. It was an unrestored part so the terrain was very rugged. It was really beautiful though, and definitely worth it.
Yesterday, I went to the underground city. Its a huge series of tunnels that Mao built during the cold war in case of nuclear attack. It has the pottential to house 300,000 people, and has movie theatres and an ice skating rink. People used to live down there but its closed down now because there was too much disease. I also saw an acrobatic show which was great, although the costumes, music and set hadn't been changed since the 80's. I'm taking the train to xi'an tomorrow night. I've been travelling with Michelle, a girl from New Zealand, which has been nice.
