Very uncomfortable train journey. Lights stayed on, no room for feet, chatter all night long, noisy people selling food....... thank God for the sleeper on the return. Walked to 7 Sages YH. Great place and excellent room. Crashed on the bed for a couple hours. Lunch at hostel then ride on Xian City Wall; excellent but very hot. Spent the early evening at the Big Goose Pagoda for the light, sound and laser show. Taxi back to hostel; a very vibrant city.
