This is the fixed ming daoshi strat-model - required for most Chinese mod campaigns to work on Western systems - including for this mod Republic of China 1924. The folder needs to be extracted using the latest or most recent version of WinRAR (WinZip could also do) and then you'd just have to place it inside of the SEGA\Medieval II Total War\Mods\"Your-Chinese-Mod"\data\models_strat-folder - replacing the files already there. When this is done you should be able to enter the campaigns of most Chinese mods - without getting the graphical error CTD.
