I stopped reading after the Xiangu. This is too cancerous.
My conclusion: this guy has 0,00000% skill in programming and designing. Yes, of course many things are bad form a historical view of point. Sho-ko-nu's are probably still there as it is an iconic weapon. You should be proud of that. It would surprise me if you could say anything iconic about my country, Belgium. And believe me, if the devs could get their hands on a very interesting replacement for it, they would take the opportunity.
Another thing: change your tone. The complaints about the refugees cards is most probably true, these "errors" are still there due to these being minor but time-consuming to change (considering the team has no Chinese insiders). If you had made a much clearer (the font size makes it difficult to read) and nicer request, I'm sure the team would've taken this into consideration. As I said, the team has no Chinese history experts, so your help could be very welcome.
