Today I traveled from Pu Dong to Hongqiao railway station (1 hour journey),

intending on traveling to Hangzhou. I COULDN'T GET A TICKET BECAUSE I DID NOT HAVE MY PASSPORT WITH ME!!!! What's up with that??? I've taken long-distance buses and ferries here, and never showed my passport. What a stupid rule. To need a passport to take a domestic train for a 40 minute ride, it took me longer to arrive to the station via the metro--only to have to turn back around. Thanks so much for wasting my time and for not informing customers correctly.
