Am I allowed to travel all cities in China? Are there any limitations?

Answer 1

There is a number of so called "closed areas", that you are not allowed to travel to on a normal tourist visa. For some you can obtain an "Alien Travel Permit" but some are downright off-limits for foreigners. You won't get a permit for these and get into trouble if you're caught there.
But nearly all places of any interest for a tourist are free to go with the notable exception Tibet.
The regulations about the permit you need for Tibet are changing frequently, but expect that you need a travel permit for Tibet and that there are only three legal ways to go there: fly into Lhasa, or overland from Golmud or Kathmandu. All other routes, especially the one down from Kashgar are closed areas.
I travelled a lot in China and the only other time I had to obtain an Alien Travel Permit was to get to a village on the Amur river right on the Russian border, so unless you plan to go to Tibet it's quite unlikely that you'll face problems with closed areas.

Answer 2

If you are American, no limitations - but in some towns, you may have to register stating that you are staying there for the night.

If you are following a tourist group, stick to the group and you will face no problems.

If you are traveling alone, with a companion or not in a group, the authorities have a right to question your coming ins and going whereabouts.

Detention is possible if they felt that there is a violation of your visa.

I have been traveling in and out and no problem so far.
