Also I'm curious since you've been taking all of these quizzes if you think that the type of questions I am doing are of good quality or if I should try to change it up a little more
There is so much to talk about for cities of this size that it's hard to not add the basic stuff, my New York and Chicago ones have alot more of the expected questions than my Sparta or Carthage ones. That's why I enjoy doing more medium sized ones more.
I'd usually aim to have at least 1 or 2 "unique questions" basically ones you won't find being asked on any other one, something wholly unique to Shanghai, obviously it's not easy to find something like that always.
The second sino-japanese war is apart of world war 2, so I suggest changing WW2 with something else.
I think the questions here are good
