34 hour Train and No sleepers

I arrived in Nanning last night after a 9 hour bus ride from Hanoi. I stopped at the train station and there were only hard seats, no sleepers, not until the 22nd. I can't stay in Nanning till the 22nd. So I bought the cheap $42 ticket and will be sitting on a train for the next 34 hours to Xian! I will leave today at noon and should arrive at 10 pm.

I am off to Wal-Mart to buy food for the train ride.
