The mountain range system of Baekdudaegan Mountain Range and Goto Basin.

 Baekdudaegan Mountain Range is a Korean spine that starts at Baekdusan Mountain and ends at Jirisan Mountain, and not only reflects the natural view of our ancestors from a long time ago, but also accurately points out the flow of mountains and water on this land, which is generally known as the Taebaeksan Mountain Range and Sobaeksan Mountain Range. Summarizing the concept of mountain stalks presented by San Gyeong-pyo, known as the work of Yeoam Shin Kyung-jun (1712~1781), is that "mountain cannot cross the water, and water does not cross the mountain." Baekdudaegan Mountain is a 1,400km mountain range that starts at Baekdusan Mountain and ends at Jirisan Mountain. In other words, you can start from Janggunbong Peak of Baekdusan Mountain and run to Cheonwangbong Peak of Jirisan Mountain without crossing the waterway even once along the ridge of Baekdudaegan Mountain. Baekdudaegan Mountain Range, which flows down from Baekdusan Mountain, passes through Geumgangsan Mountain, passes Hyangnobong Peak, reaches Seoraksan Mountain, passes through Jeombongsan Mountain and Odaesan Mountain, passes Taebaeksan Mountain, Sobaeksan Mountain, Songnisan Mountain, and Deokyusan Mountain, and ends at Cheonwangbong Peak in Jirisan Mountain. The length of the south Korean section of Baekdudaegan Mountain Range from Hyangnobong Peak at the bottom of Geumgangsan Mountain to Cheonwangbong Peak of Jirisan Mountain is about 670km. The main ridge between Seoraksan Mountain and Baekdudaegan Mountain runs through Jinburyeong Pass and Masan to Misiryeong Pass, passes through Hwangcheolbong Peak and Resistanceryeong Pass, and connects to Jeombongsan Mountain through Madeungryeong Pass, Dinosaur Tomb, Heueunggak Shelter, Daecheongbong Peak, Jungcheongbong Peak, Endcheong, and Hangyeryeong Pass. The widespread spread of the concept of Baekdudaegan Mountain Range was attributed to the pioneering efforts of Cho Seok-pil (Gwangju Hanbit Pediatric Clinic) in the 1990s when Lee Woo-hyung discovered the mountain slope at an old bookstore in Insa-dong, Seoul in 1986 and the monthly publishing of books. After that, the number of mountaineers running the Baekdudaegan Mountain Range increased, and the term Baekdudaegan Mountain Range was established in the institutional media. The concept of mountain ranges that we currently know, such as the Taebaeksan Mountain Range and the Sobaeksan Mountain Range, has been uncritically continued since Japanese geographer Goto Basin published a geological research paper in 1903. The "mountain range" is a geological line artificially processed by classifying mountains on the ground based on the geological structure line in the ground. In other words, the "Taebaek Mountains" refers to the geological structure in the ground and was created for the purpose of Japan's exploitation of underground resources, which is a necessary concept only in geology, almost useless to understand our river soil as a whole. When the flow of water originating from the mountain changes, the climate and soil change, and the characteristics of the people living against it change, and we are ridiculously insensitive to the Japanese geographical concept and destroying our land without much thought.(Refer to Data-1) Until the 19th century, there was no word "mountain range" in Korea. This word was introduced into Korea by the Japanese in the early 20th century. The Koto Basin of the University of Eastern Economy in Japan visited Korea twice between 1900 and 1902. In addition, the results of studying the geography and mountain ranges of Korea were published in 1903. When Shoay Yatsu published "Korean Geography" in Japan in 1904, the topographic sector included the framework of this theory as it was. This "Korean Geography," along with other Korean geography-related books, was published amid Japanese companies and civilians' penetration into the domestic market and Japan's ambition to dominate the colony. This is in contrast to Japan's current translation and supply of land geography textbooks from dozens of countries around the world. Korea's geographic textbook "Support for High School Sohak," published in 1908, is not much different from this "Korean Geography" published first in Japan. The terrain sector is almost the same. Geography written by the needs of the Japanese came into Korea, which was unilaterally accepted by Japan as it is in geography textbooks. Goto changed the name of Baekdusan Mountain's main peak to Daejeongbong Peak after their king's name, while disparaging Joseon's land as a rabbit-shaped national theory. They went one step further and committed abuse to create a mountain range that was missing or to eliminate the mountain range that was being removed. However, I copied these books indiscriminately without sufficient verification. Not only textbooks from schools at all levels, but also "Korea Support" published by the Ministry of Construction's National Geographic Institute accepts Goto's thesis without exception. The principle of natural geography is that mountains are trapped and water flows. It is the basis of the human geography view that the river basin surrounded by mountain ranges forms a community. Therefore, the achievements of Korean studies research and classification, such as history, folk language, music, architecture, food, climate, etc., should be based on geographic recognition. Geographic recognition, of course, refers to the actual mountain and river streams. Nevertheless, the current Korean studies are being practiced based on the invisible virtual line, that is, the mountain range. The concept of a mountain range created based on false geographic perception after touring Korea for a short period of only 14 months should be corrected as soon as possible.
