下面一堆TXT文件。看英文知道有东亚、中亚等等
就好比11_east_asia.txt这个文件下面有一下内容(STATE_ANNAM等于里面的安南)：
STATE_ANNAM = {
id = 290
subsistence_building = "building_subsistence_farms"
provinces = { "xEF3060" "xEDBFB1" "xFAB663" "xC46194" "xA01EF1" "xB070A0" "xC08B17" "x3070A0" "x5109BC" "x2A870A" "xF22C8B" "x307020" "x0BE805" "x7A5ACC" "x9E5CF8" "xEEB5DD" "xE63DDE" }
traits = { state_trait_indochinese_forest }
city = "xA01EF1"
port = "x2A870A"
farm = "xB070A0"
mine = "xEDBFB1"
wood = "x307020"
arable_land = 548 这里可用土地面积我改的
arable_resources = { bg_rice_farms bg_livestock_ranches bg_coffee_plantations bg_cotton_plantations bg_silk_plantations bg_dye_plantations bg_tea_plantations bg_sugar_plantations bg_banana_plantations }
capped_resources = {
bg_coal_mining = 274 煤矿数量，本来没有煤矿，我加的
bg_iron_mining = 68 铁矿
bg_lead_mining = 80 铅矿
bg_sulfur_mining = 78 硫磺矿
bg_logging = 78 树木
bg_fishing = 8 鱼点
}
resource = {
type = "bg_rubber" 橡胶树
undiscovered_amount = 46 数量46
}
resource = {
type = "bg_oil_extraction" 石油
undiscovered_amount = 155 数量
discover_amount_max = 155 最大数量改成一致就好了
}
naval_exit_id = 3054
--------------------------------------------------------------------------------------
以上的你可以把我加的中文去掉就能直接用来替换你里面的安南，当然最好把那个文件夹备份一下，万一改爆机了。
{ bg_rice_farms bg_livestock_ranches bg_coffee_plantations bg_cotton_plantations bg_silk_plantations bg_dye_plantations bg_tea_plantations bg_sugar_plantations bg_banana_plantations }
分别是大米、牧场、咖啡、棉花、丝绸、染料、茶叶、糖类作物、香蕉（不是橡胶）因为安南是热带所以我没有加上黑麦和小麦。

再说一点，改了之后只有开新档才会生效的。
另外，我发现一开始我没搞明白，那里只有地区，兰芳是政权名称非地区名称。
兰芳所在的地区叫STATE_WEST_BORNEO 在12_indonesia.txt 这个文件下面
