Ancient China
Modern China
In Ancient China, maps were considered classified unless you had authorisation from the generals. Also many people didn't try looking for maps because if you were to find one you would immediately think it was fake because a lot of countries would fake their maps in case of enemies finding the locations of cities and colonies. The difference between the Ancient Chinese and Modern Chinese maps were that the Ancient maps were much more simple and easy to understand whereas the Modern map is more complicated with all the new and differently named cities.
