We took an overnight train from Shanghai to Xi’an to see the Terracotta Warriors. There was very little privacy on the overnight train. Compartments had six berths and an open doorway to the corridor. We shared our compartment with a university student and a lovely Chinese family. In fact, there were many families with young children on our train car. The next morning, as I was stretching my legs in the corridor, two mothers with young children wandered by our compartment and popped in to visit the family. They sat on my berth and played for nearly an hour while I snapped a few photos. Poor Sarah was trapped in the middle berth the whole time.
