I will be in Chongqing for 1 day, arriving in the evening then leaving tomorrow evening. I wonder if I should stay in Chongqing and explore the city, or go visit the Dazu Carvings for the day instead? This is part of a larger trip that includes Chengdu, Hangzhou and Nanjing, and I've seen plenty of temples and Chinese architecture already. The attractions at Chongqing don't really seem that interesting to me, just similar attractions in other Chinese cities, so I'm tempted to go to Dazu instead. Is there anything I would miss in Chongqing?
Also, I would be there on February 10th, during Spring Festival, do you think the Dazu Carvings will be crowded? And do you think it is easy to go from Chongqing to Dazu and back in 1 day, since my train leaves in the evening, around 8 pm?
