how is the weather for next week in jinzhou?is there any foreign or islamic restourant or fast food?

Well, it will be a little cold. The average temp during next week should be nearly zero centigrade and you may meet rainy day next Friday. Therefore, I suggest you take along the wool coat or jacket plus cardigan.
Don't worry! The Halal Restaurants are easily to be found there and you can also enjoy the fast food at the local McDonald and KFC.
