Date of Entry, visiting address and phone numbers?

I am travelling with a friend from Canada to China for our holidays. We don't have a exact day for entry and don't know where we will be staying at yet, so we do not have any phone numbers or addresses for you. We plan to enter China in the first week of March, 2012 and do some travelling around there. I could pick out a few addresses and phone numbers from my guide book if this helps with filling out the application form.
