但有一个新的问题,在名誉头衔中,天子头衔 title_china_emperor = {# this title is not granted by a character to another, it is automatically obtained # when one character becomes emperor of china. It is used solely to identify them as such is_offmap_holder = yes offmap_power = offmap_china show_as_title = yes dignity = 1000 # this should always be higher than 0, or it won't be applied in all cases } 其中is_offmap_holder = yes与offmap_power = offmap_china这两句表示什么意思?
