A. Never take photos in sensitive areas such as military base, airfield, etc. and other sensitive areas where photography is forbidden.

B. Ask for permission before taking photos of other people.

C. Some tourist attractions do not allow photography. So you'd better look for the sign or ask for the staffs before taking photos.
