north korea actually gained approximately km from china in the treaty and here's a th century book by chong yagyong titled korea's northern border reigion in a korean sourcebook compilation translated by peter hacksoo lee a long time ago the area north of the tumen river was the land of the su shen people it has not been under our control since the time of the three han the ''southern slopes of mount changbaek where both the tumen and yalu rivers have their headwaters lay within our territory but the winding ridges and layers of peaks make the exact location of the border unclear however emperor k'ang hsi in the final years of his reign ordered area commander wu la wu la ts'ung kuan muk'eteng to delineate the border and erect a stone boundary marker as a result the border between those two rivers is clear as well emphasis mine here's another study of the us north korea border in by the us dept of state which makes no mention of north korea owning the entire mountain and another which says that china actually made concessions to nk on the border in the only sources that seem to claim that korea once owned the entire place are some recent tabloid news articles that protest china conducting activities on its own side of the border and of course a few ultranationalist sites but please enlighten me if you can provide other reliable sources as well on another rather amusing note it does seem my userboxes are being quite effective experiment in showing which users are capable of judging others by the content their edits and which prefer to judge a book by it's cover and lash out emotionally should be made in a new section on the talk page no further edits should be made to this section the result of the debate was no move ' requested move chonji tianchi the name was unilaterally moved from tianchi to chonji without concensus for pov reasons cited in move and talk page such as that it should be korean it's on the border between china and korea another reason cited was that the name of the baekdu mountain page is korean as well however a google search shows nearly hits for tianchi and and less than each for chonji and cheonji that's two orders of magnitude in difference the preceding was quoted by yuje survey add support or oppose followed by a brief explanation then sign your opinion with support for the most common name searches for chonji for all the most popular search engines combined give less than a thousand hits search on google scholar shows only uses of the name chonji for the lake the use of chonji as a clear common name doesn't apply because it's not common support per yuje naming conventions gives preference to the more popular name oppose per visviva and my previous comments like i said before we need to use the most common name that is the clearest because tianchi is a name for many other places in china as shown chonji is nowhere near common chonji barely shows up any hits therefore isn't a viable alternative for a clear alternative name oppose look at my reason below comment the proposition seems to be flawed given that tianchi is now an article on the lake in urumqi if this article is moved it would need to go somewhere else perhaps tianchi changbaishan or even heh heh tianchi paektusan but then again maybe tianchi jilin if we must'' have a straw poll it would be helpful to know what the full suggested title is comment''' the issue you brought up is a legitimate one and shouldn't be ignored thus perhaps tianchi could be a disambiguation page or this page could be moved back to the original and there could be a tianchi disambiguation page either one is a reasonable alterna
