One of the highlights of our trip to China was Xi'an, where we saw the Terra Cotta Warriors. They were so impressive, but there is also a lot of other things to see here. The city wall is impressive and there is a great Tang Dynasty dinner show that was very entertaining.
What a beautiful and amazing place in Xi'an. You can see the history and the heritage of China. The more you see, the more you are interested the history of China.
I enjoyed visiting Xi'an-- it's a very walkable city with a lot of history and great food. We may have come on a good weekend, but the air quality wasn't as bad as I was expecting. I recommend it if you're in Beijing or Shanghai for at least 7 days and want to take a couple of days to go elsewhere.
Incredibly cheap, if you are willing to haggle for prices. Renting can be a bit pricey, considering that expats do not wish to purchase furniture as well relocate from one city to the next very often. As with the rest of China, you can not drink the water, but the air is only bad in winter, mostly---plenty of medical grade masks available at the local pharmacies
