I am back from Beijing, via train. Here is a short summary.
Train is Good
As I described earlier, train is efficient for business travel. But I realized there is one criteria for it to be efficient: you have to be able to sleep very well on the train. Like me, I am always sleepy, and I can sleep from the time I get to bed on the train until train is approaching the terninal station. For my friend, Jia, the trip is not that pleasant – he wakes up every one hour or sooner during the trip.
