Need to have hotel names on form?

I'm going to China as a tourist in May. Because I'm traveling elsewhere beofre this time (and need my passport in March and April), I need to apply for a visa sooner, rather than later. However, I do not have any hotel reservations yet. Is it required to have all hotel reservations confirmed, or can one simply put down the cities (Shanhai, Beijing, Xian) where I'll be going? Is that good enough
