Terrible story - Irreversible "gando" theory

 Bae Sung-joon, a researcher at the Goguryeo Research Foundation, a fantasy about the "Godo issue" of the Kyunghyang Shinmun, seems to have begun to take a breather as South Korea and China verbally agreed on understanding related to the distortion of Goguryeo history at the end of August. However, few people would think that the Northeast process, which is set in the extremely sensitive and realistic problem of agitation of the Korean-Chinese and changes in the situation on the Korean Peninsula, will be easily stopped. At this time, some academia and politicians raised the "Voidance of the Liver Convention" as a card to counter the Northeast Fair, and the slogan "Voidance of the Liver Convention" was widely distributed on broadcasting and the Internet without considering the difficulties or risks of liver problems. Now, there is a rumor on the Internet that the "100-year-old theory" (a rumor that if the territorial issue is not officially mentioned for 100 years, it will be confirmed as the territory of the occupying country), which has been talked about in the population whenever the Dokdo issue arises. However, unlike Goguryeo history 2,000 years ago, the Gando problem is a realistic territorial problem. As it is a sensitive issue with direct interests between the two countries, it should be raised on a clear basis that can confirm that "Gando Island is our land" no matter who looks at it. However, the claim of the sovereignty of Gando Island, which relies only on the claim that the "Tumen" of Baekdusan Mountain Jeonggyebi is Songhwajang River, has many problems. - The geographic scope basis is weak - First, no one knows exactly which region Gando is pointing to, claiming sovereignty over Gando Island. If Tumenjang is a tributary of Songhwajang and Songhwajang enters Heilongjiang, there is no specific discussion on whether the Songhwajang movement or the southern part of Heilongjiang are all Gando, or Wangching, Hwarang, and Yanji on the north bank of the Tuman River, where many Koreans lived from the late 19th to early 20th century. The fact that the geographical scope of the area to be claimed right now is not confirmed proves how lax the claim of Gando's sovereignty is. Second, the problem between Joseon and Cheong was which of the tributaries upstream of the Tuman River would be the border. At the time of the establishment of the Jeonggyebi Monument, Cheong regarded crossing the Yalu River and Tuman River as a border invasion, and Joseon established a policy to secure the south of the Yalu River and Tuman River as a river in response to Cheong's border investigation. At the two Jocheong border talks in 1885 and 1887, the Joseon side claimed Hairanjiang or Hongsui as the border, while the Chinese side claimed Suisui, which is farther south than Hongsui. Since the establishment of the political monument, it has been known that Tumenjang is different from the Tuman River, and it has been revealed that Tumenjang flows into Songhwajang in the late 19th century, but Songhwajang has not been raised as an official border. Third, if you ignore the "Jo-China border treaty" signed between North Korea and China and claim sovereignty over Kando Island, you may lose the whole land of Baekdusan Mountain. Cheong, who insisted on the Suisui border at the border talks, confirmed political monument and Suisui as borders by the 1909 Kando Convention, and as a result, Baekdusan Mountain Heaven and Earth became the territory of Cheong. Since the establishment of the People's Republic of China in 1949, border talks have been held again between North Korea and China, and as a result, the "Jo-China border treaty" confirmed the center of Baekdusan Mountain and Hong Su-yi as borders in 1962. For this reason, Zhu De Hai, the captain of the Yanbian Korean Autonomous Region, suffered from a traitor who sold the heaven and earth of Baekdusan Mountain to North Korea. If North Korea's "performance" is ignored and the Kando Convention is invalidated, there is a risk that half of the current Baekdusan Mountain and areas ranging from Hong Sui to Sui Sui will become disputed. -  Territorial Dispute Fire Concerns - Considering this fact, we can see how dangerous some of the "fantasy" that Gando will automatically become our land if the Gando Convention is invalidated. In fact, in the event of a "territorial dispute" between Korea and China, it may not be China but us who suffer damage. Raising the invalidation of the Kando Convention not only blinds the risks currently lurking, but also stimulates China, which is sensitive to territorial issues, making it difficult to solve the Northeast Fair issue. The urgent issue now is not to urge the government to express its official position on the liver problem, but to grasp the meaning and status of the Northeast fair amid the newly organized situation in Northeast Asia after the dismantling of the Cold War.
