DPRK/ROK Borders Should Not Be Included?

@Qiushufang: Hey- I think that the boundary lines near Ongjin County, Incheon and between the PRC and DPRK are a little strange here- did you intend to include them? It seems a little odd to me for us to project the borders of the 20th and 21st century onto ancient ages of history. Otherwise very interesting work! --Geographyinitiative (talk) 23:10, 25 February 2021 (UTC)
