Need a bit of guidance

Hi there,

I am hoping to travel to china in a few weeks time. But the only documents I have at the moment are my round trip tickets which are about 5 weeks apart. I am just wondering if this will be enough to obtain my L visa or will I have to have all the reservation booking before I apply for it? I would prefer not to have to book everything as this will restrict things if I want to stay a few days longer in a certain area.
