I am back from Hangzhou, and I would say, I will never drive to Hangzhou again.
Hangzhou is only 45 minutes away via high-speed rail, and the transportation to and back the railway station is so simple for me, and the only bottle neck is to get to hotel from the Hangzhou railway station. It takes for ever to build the metro in Hangzhou. Despite that, I should enjoy the relaxed time in Hangzhou via taxi, or local cars, not driving. I am very tired after the long trip.
