>>507599499>That's Korean my guy. But it basically says the "Hwan-Guk" (fictional Korean empire) and it's spheres of influence.To be honest, it's not really without basis, as in some myths, Koreans are the descendants of Chiyou, who lost against Huangdi for the domination of China, so it's no brainer that they still keep that bitter loser mentality. Moreover, we know that Chiyou and Dongyi people after all were just a branch of Shennong tribe, so that even reinforce their bitter mentality.
A little interesting trivia is that there is a "fake story" from history of Nguyen clan of Vietnam, claiming that the ancestor of Shennong tribe, Fuxi, was originally from Kunlun mountain (Taklamakan desert), after being defeated in battle, they ran to Long (Loess plateau) then became Shennong, so the map of Hwan-Guk might not totally be fiction.
The problem of East Asian historical research is that:
1. The tendency to claim oneself as the "true descendant" of "great ancestors", the devalue or outright disregard other branches as enemies, fakes, unorthodox, etc. (all East Asians are guilty of this, even China as the "orthodox" branch)
2. The method of writing in the ancient times. They used short-lived materials as media of information storage (bamboo for example), therefore, it's very hard to uncover primary sources intact (so the Bamboo Annals https://en.wikipedia.org/wiki/Bamboo_Annals can be considered as a very valuable source, even if we cannot confirm the content is true or not, kek). Moreover, in the more ancient times (maybe antideluvian), the myths said that people in that era used tied-knots as a way of keeping information instead of writing, at first I didn't know if it's true or not, but after reading about Incan Quipu: https://en.wikipedia.org/wiki/Quipu I think it's totally true, and then it means a lot of valuable historical sources can be considered lost forever, unless by some miracles, you uncover those knots intact after ten thousands of years...
