fly zone

Are you allowed to fly if you register online in China? I am mostly looking to fly in empty places around Himalaya. Where is a good no fly zone map?

I am going to have a tour in Rome, Florence, Vince, Milan in Italy and Paris in France. can i fly drone in those cities? where can i check the fly zone information? of course, i do not plan to fly in those government building. but how about in the air of attractions in those cities?
