Just put down the hotel your staying at, your going there as a tourist, on a tourist visa.
I would never put down a ladies name, ID, or her address. I've always found the less you tell them the better....
There are very few restrictions on where you can go in China. There are hot spots from time to time where there is a bit of civil unrest going on, and a couple of political gremlins they would rather you not know too much about, like Tibet. But apart from that you can go pretty much anywhere you want to visit....
By the way, Tibet is not totally out of the question if you want to visit, but there will be a few more questions and answers as why you want to visit Tibet!! So best, you don't state that your profession is a journalist...haha!!
