we are going to visit beijing on 10-14 november.can we visit Great Wall of China during that time?

You must refer to Badaling Great Wall, right?
If yes, the temperature may be around 45 F. It will be a little bit cold. But you can still visit there. Don't worry. However, generally speaking, it won't have snow at that time. You are suggested to prepare overcoats, sweaters, long johns and pants. Have fun!
