Terra Cotta Warriors, but let me explain. We went to Xi'an just to see them. We were trying to save money by taking the train from Beijing. 20 hot hours later, we were there, tired and a bit miserable. This was late June and it was bloody hot! Had we either paid for a sleeper car or airplane ticket (or had the train be on time), I believe we would have had a totally different experience. We struggled to be excited about them.
