Just an error I noticed for a long time and still exists in the current patch, the Chinese man-at-arms (palace guards) actually call themselves “heavy cavalry” (“chong ki bing”). (of course, I think this is a good joke because the Chinese man-at-arms are the de facto cavalry for the Chinese civ)
Another issue I remember is that the Chinese grenadiers actually call themselves “archers” (“gong chan show”) throughout the previous patches. I am not sure if it is still a problem in the current patch.
I will post again if I notice other errors in the voice
