No, I'm just trying to set the record straight. Don't talk about politics here, we're trying to get the historical facts right. So don't use examples carelessly. I mean, look Copenhagen is linked to Malmo, hence Copenhagen is a part of southern Sweden?? Use your examples correctly, otherwise people will misread your writing.
Look, this is a very pedantic and worthless argument to be having here. I'm just trying to say, you carelessly said Viet and Tai peoples were kicked out of Shanghai. That's a dangerous thing to say (because Shanghai is totally not relevant here) because people might start quoting you and saying how Shanghai doesn't belong to China. You have to be careful in these topics as things can go wrong very quickly. You have to be precise when it matters.
