You can suggest canonical city locations here. I consider the "canonical" city locations the cities you would like to see appear in most games, and encourage the AI to found. For example, in the old map the canonical French cities are Paris, Bordeaux and Marseille. This does not mean that it has to be deterministic in the game. This is part of Phase I of developing the new map, see here for a general overview. Generally, canonical locations should not be adjacent to each other, but sometimes it makes sense to denote things that way. For example, Hangzhou and Shanghai border each other and cannot coexist, they are both important cities whose canonical locations are relevant for resource placement and one of them should be founded in every game. Use your judgment for this. To make a suggestion, either place a marker with the city name on the tile, or found a city there with WB and give it the appropriate name. It's not too important which of the names of a given city you use (e.g. Constantinople vs. Istanbul or any of their various translations) as long as things are clear. Don't let resources on the tile stop you from suggesting it as a canonical location. The goal of this exercise is to find out which resources are on the wrong tiles and need to be moved.
