Not all the beds on the train were full until 4AM. That’s when I was woken up and had to move my backpack off the empty bed above me for new people. Some people bring there small children and sleep in the same small bed. I think in my 6ft by 6ft space there were 8 people sleeping in 6 beds. I don’t think they get many foreigners on this route either. I think most foreigners either fly or go to different cities, so I might be the only one on the entire train.
I got to Hangzhou about 4PM I think. It gets dark about 5PM, so I found a place to stay and then didn’t really see anything.
