Regarding the reality of Dangun Joseon,

 First... Issues related to Jeon Sam-han The theory related to Jeon Sam-han has not been able to provide any significant argument on this issue since some ethnic historians such as Shin Chae-ho and Jeong In-bo argued. However, academia only speculates that some of the members of Samhan may have migrated from north of the Korean Peninsula. However, I am confident that some of the issues of ancient Korean history cannot be solved without acknowledging Jeon Sam-han. For example, the problem that a reporter from the Eun Dynasty became the king of Joseon, that Wiman of the Yeon Dynasty drove out the descendant of the reporter and built Wimanjoseon on the land, that Jinguk appeared in the historical image after Wimanjoseon was established, and that a private army was established. These problems were taken very sensitively because they were waiting for expansion as a problem that Korean history began under Chinese rule. Thus, the current historical academia argued that Wiman, who denied the reporter Joseon at all or established Wiman Joseon, was a Joseon person because he had worn Joseon clothes and topknots. More and more theories were raised when the issue of Hansagun, which was established at the site of the collapse of Wimanjoseon. The theory that Hansa-gun was installed in Yoseo, Liaodong outside the Korean Peninsula, and that it was installed around Pyongyang on the Korean Peninsula was raised. This started from the difference in perspective between seeing defeat as a orchid in the Yoseo region or the Daedong River in the Korean Peninsula. This problem also led to the theory that the center of Gojoseon and Wimanjoseon was Yodong and Yoseo, and that Pyongyang was initially Yodong and Yoseo to compensate for this, but Pyongyang was the center in the late period. However, neither theory was able to clearly explain without contradiction. Among them, there was also a theory that confused the Nakrangguk of Choi Clan and the Nakranggun of Hansagun established by Koreans. In addition, more confusion was brought about in the issue of the true country. Because the records of "Jinhan is the true country of the past" in KEPCO and "Samhan was all the true country of the past" in "Huhanseo" made the existence of the true country more ambiguous. This is also the case in explaining the process of establishing Samhan. In "Buksa", "Byeonhan was in the land of the...Han Dynasty." It was 2,000 ri in width and 3,000 ri in species." Records such as "Bunhan-hyeon in Liaodong refers to the old land of Byeonhan" in the <Donggyeong Notice> made us doubt the existing theory that Samhan was on the Korean Peninsula. These records are ignored by the current history academia because they do not make sense or are misunderstandings of future generations. The reason for these problems was that all of the current historical academia influenced by Lee Byung-do interpreted Joseon as a governing area. However, ethnic historians solved this problem by revealing that Samhan (Jeon Samhan) already existed before Samhan, south of the Korean Peninsula. This theory of three-han movement is not limited to three-han problems. It is a fundamental problem across the entire Korean history. If these important arguments are ignored because they are not clearly recorded in any literature, various problems in the ancient history of Korea will remain as homework that lingers forever. Thus, I intend to continue to present various issues related to the existence, location, domain, and Samhan movement theory in this historical special, especially the issue of Giza Joseon, Wiman Joseon, and Hansa-gun. Second... This is an overview of the Samhan migration theory. Samhan Lee Dong-seol was the first argument presented by Shin Chae-ho in "Before and After Samhan High School" and "Joseon Sanggosa," and has since been supported by some re-night scholars such as Choi Dong and Moon Jung-chang. However, there were no significant papers in academia after Shin Chae-ho and Jeong In-bo, but the theory of Samhan movement was ignored after Lee Byung-do conducted a study on Samhan in <The History of the Samhan Problem>. The theory related to the movement of Samhan or the separation of Samjoseon is the argument that Joseon was politically separated and governed by Baljoseon, Balsiksin, Bunhan, Jinbeonjoseon, Makjoseon, and Beonjoseon, which are occasionally seen in the literature. According to this, Jinjoseon is the center of the Gojoseon ruling system, where Dangun is located, and Makjoseon and Beonjoseon are the places where Buwang are located, and were indirectly ruled by Jinjoseon. The Jinjoseon Line extends roughly to Nammanju and Liaodong in the east of Yoha and Manchuria in the north of the Yalu River, and Makjoseon is located on the Korean Peninsula and Beonjoseon is located in the northeastern part of China. In particular, Shin Chae-ho said that in the 4th century of the B.C., Gojoseon became the king of Beonjoseon, and from then on, the era of separation of the Three Kingdoms has arrived in earnest. In particular, after the collapse of the Beonjoseon, some of the immigrants migrated to Makjoseon (Mahan) on the Korean Peninsula to form Byeonhanbu and Jinhanbu, thereby establishing the Later Three Kingdoms. Among the three Joseon Dynasty, Jinjoseon was a political center, Beonjoseon was a cultural center, and Makjoseon on the Korean Peninsula appeared in the literature only after the standards of King Beonjo moved. Third... The representative scholars who recognized Jeon Sam-han, a scholar who recognized the reality of Korea, are Shin Chae-ho, Jeong In-bo, Ahn Jae-hong, Choi Dong, and Moon Jung-chang. Shin Chae-ho, who claimed this argument for the first time, explained the separation of the Three Joseon Dynasty in "Before and After Samhan High School" as follows, focusing on the theory of Samhan Lee Dong-seol. First, Dangun Wanggum established the Three Kingdoms of Sinhan, Bulhan, and Malhan based on the concept of Samshin Ohje, and placed Samgyeong, and below them, there were five-part systems such as Dotga, Gaega, Soga, Malga, and Shinga. Second, as for the location of the Samjo Line, Shinhan used the capital of Asra, that is, Harpin, as the capital of Manchuria, such as Gilim, Heukryong, and Bulhan as Ariti, and Gaepyeong as the capital of the present Pyongyang and the Korean Peninsula. Third, it was around the 4th century BC that the Three Kingdoms were completely separated politically and began to take on the character of an independent state. Fourth, regarding the surname, Shinjo-seon is the descendant of the Dangun Wanggeom clan, Buljo-seon is the descendant of the reporter, and Maljo-seon is the Han clan. Fifth, emphasizing the theory of Samhan Lee Dong-seol, after the collapse of Shin and Bulyang Joseon, immigrants flowed into Maljoseon on the Korean Peninsula and established Jinhan and Buhan, respectively, to form Samhan along with Mahan. Although Jeong In-bo did not publish a separate paper on the separation of the Three Joseon Dynasty, he agreed with Shin Chae-ho's claim in the Chosun History Study, and it can be seen that Ahn Jae-hong was divided into three and governed by Shin Chae-ho was influenced. After Shin Chae-ho, Choi Dong, a doctor of literature and medicine, studied the separation of the Three Kingdoms in depth. He published a research paper titled "Chosun Sanggo National History" and conducted intensive research on Gojoseon. Unlike Shin Chae-ho, he identified the full-fledged separation period of the Three Joseon Dynasty as the Journalist Joseon Dynasty (BC1200-BC194). In particular, regarding the reporter who led 3,000 people from the Eun Dynasty, he said that he only stayed in Beonjoseon and was confused with the reporter, the king of Joseon, and was misled as if he had ruled Joseon. Moon Jeong-chang also agreed, but it was found that there were more Yemaek Joseon in addition to Jin, Beon, and Mak Samjo. Fourth...According to Jeong In-bo, the name of Joseon, which appeared in the literature, Jusin, Jiksin, Suksin, Yeojin, etc., which started from Jusin, meaning Gwantojigyeong, that is, the world, all have the same tone and represent Joseon. Choi Dong, a doctor of literature, said that Joseon originated from "Siujin," which means the presidential country of the East. "Shi" means the east of ancient Joseon, "Woo" means large, and "Jin" means gun and representative. Therefore, it is said that if Joseon is marked in letters of meaning, it is Dongdaejin, and if it is marked in sound, it appears in the literature as Joseon, Suksin, Sinju, and Yeojin. Therefore, Jinjoseon, which can be said to be the ruling country of Gojoseon, was also described as Jinguk-General Gojoseon. The record of "Jinhan is the Jinguk of the past" in <Samgukji> and "Samhan was all the Jinguk of the past" in <Huhanseo> show that Jinjoseon (Jinhan) was the Jinguk and the governor-general of Samhan. In addition, the "beon" of Beonjoseon corresponds to the "beol" of Korean, and can be marked as Bal, Mac, Byeon, Byeon, Byeon, and Bun. Therefore, Beonjoseon was expressed in "Gwanja" as Baljoseon, Balsiksin, Balsuksin, Yemaekjoseon, and Mac, and later appeared as Byeonhan, Byeonhan, and Bunhan. In addition, Makjoseon's membrane corresponds to "ma" in Korean, meaning south, and can be seen from the name of "Maparam" and Namsan Mountain as "Mamoe". Ma can be written in Chinese characters such as Mok, Ma, Mae, and Ma, so Makjoseon was later written as Mahan. Samjoseon was marked in various ways on Chinese literature according to the times. An article from the time of Hanara says, "Sagi" refers to Sanyong and Balsiksin to the north, Jangi and Doi to the east, and Sanyong is the jurisdiction of Beonjoseon, Jangi is Jinjoseon, and Doi refers to Makjoseon across the sea. In addition, Sindangseo said, "There is Janginguk to the east of Byeonhan," but Byeonhan refers to Beonjoseon, and Janginguk to the east of Byeonhan refers to Jinjoseon. In general, Jinjoseon appeared in Chinese literature as Dongho, Zhang Yi, Jang In-guk, and Dae In-guk, while Makjoseon was marked as Mahan and Doi. Since Beonjoseon is attached to China, it was marked in various ways such as Baljoseon, Balsiksin, Buhan, Yemaek, Maeksuksin, Mac, and Yemaekjoseon, and its jurisdictions were replaced by Gojukguk, Sanyong, and Yeongji. Fifth...In order to prove the location and area of the former three countries, the location of Yosu and Yosu Jeon Samhan must be confirmed. This is because depending on where Yosu and defeat are located, the center of Gojoseon may fluctuate outside the Korean Peninsula or become the Pyongyang of the Korean Peninsula. Ethnic historians generally viewed the river as outside the Korean Peninsula, and empirical historians such as Lee Byung-do, who led the Korean historical community after the Korean War, viewed it as on the Korean Peninsula.

First, I will testify the position of the ascetic. It can be said that the historical evidence of Yosu is very important because the location of Yosu varies depending on where Yosu is, as well as whether the Joseon area is outside or inside the Korean Peninsula. It is said that the east side is Yodong and the west side is Yoseo, so if you know the name of Yodong, you can see which river Yoha was. In <Seojeon>, it was said, "The lord is a fluctuation", and in <Yosajiri>, it said, "Youngju was originally Gojukguk during the Eun Dynasty, belonged to Yoseo-gun during the Qin Dynasty, and became Changnyogun during the Han Dynasty." This means that Yeongju was today's Changryo (in the Yoseo region), and that the fluctuation at one time was today's Yoseo according to the record of "Youngju is fluctuation." It distinguishes between yoseo and fluctuation based on yoseo, which means that today's orchid was yoseo at the time. At that time, fluctuations were today's yoseo, and the yoseo at that time became today's Habukseong Fortress. In Tongjeon, a record of the Tang Dynasty, it was said that "Yodong is the land of the old Byeongju and Yeongju." Based on the Tang Dynasty, it means that in the past, Byeongju and Yeongju were in Liaodong, and since Byeongju pointed to Yuju and Yeongju pointed to Changnyo, it can be said that Liaodong at that time corresponds to today's Yoseo region. - Yuju and Changryo are both in the Yoseo region. - In other words, it can be seen that fluctuations are related to today's orchids. In the "Daemyeong Il Notice", "Both Yodong and Joseon are in the territory," but since the territory is Yeongju, it can be seen that Yodong and Joseon were also related to Nanha. "Yeo Si Chun-chu" said, "Yosu comes out of Jiseoksan Mountain and flows east from the north of the bird and flows straight into the sea at the southwest of Liaodong." This was explained in the same book, "Yosu comes out of Jiseoksan Mountain and flows east from the north of the bird and enters the sea at the southwest of Liaodong," and these two records suggest that Jiseoksan Mountain is Galseoksan Mountain. However, according to the records of the Han Dynasty on Galseoksan Mountain, Galseoksan Mountain is located in Nakrang Suseonghyeon, the Han Dynasty. Jangseong is cut off from Yosu in the east and originates here, he said. If so, it means that Galseoksan Mountain is in today's Changryo region (downstream of Nanha). What can be seen from these three documents is 1) Galseoksan Mountain is located in the Changryo region, 2) Yosu is today's orchid, and 3) Birds penetrate the orchid from Joyang to Galseoksan Mountain in the Changryo region. 4)Jangseong (the Great Wall of the Qin Dynasty) is also consistent with birds. Therefore, Yosu refers to today's orchids until the Han Dynasty, and it is said that Yosu in the west and fluctuated in the east centered on this orchard. Next time, I will testify the defeat. According to the Joseon Yeoljeon, a record of defeat in the Han Dynasty, it was said that " defeat comes out of the southwest of the bird of Liaodong and enters the sea in the southwest of Nakrang-hyeon." This is in line with the record and expression of "Hoe Man", "Yosu leaves Galseoksan Mountain and flows eastward from the north of the bird and enters the sea at the southwest of fluctuation." In other words, in these two records, there is a strong possibility that the defeat will be a constant or its tributary, and that the defeat will be as difficult or its tributary as the constant. In addition, there is a similar phrase in "Hanseojiriji," "Paesu comes out of the bird of Liaodong and reaches the west of Nakranghyeon to the southwest and flows into the sea." In the same book, Pesu is also expressed as Pesu, and it is said that "Pesu comes out of the southwest of the outside of the bird and enters Buhan-hyeon." In other words, 水는 is the same word as 水와 and refers to Nanha, suggesting that Bunhan-hyeon is near the downstream of Nanha. It also supports the record of "Loser leaves Nubang-hyeon, Nakrang-gun and goes east to sea" and "Loser leaves Nakrang, passes Impae-hyeon southeast, and enters the sea eastward." From these records, it can be seen that defeat and demand were Nanha or its tributaries until the previous time. Sixth... The capital and location of... The capital of Joseon on Gojoseon Island was usually called Pyongyang, Imgeomseong Fortress, Wangheomseong Fortress, Wanggeomseong Fortress, Yangpyeong, Humdok, etc. However, since there are several places in the literature about the capital and location of Gojoseon, the theory of fluctuation, yoseo, and Pyongyang confronted the capital of Gojoseon. However, this is also a problem that cannot be solved by the existing view of history that sees Joseon as a system. Therefore, in this argument, the capital of Joseon shown in Yoseo was viewed as the capital of Beonjoseon, the capital of Gojoseon in Liao-dong was viewed as the capital of Jinjoseon, and Pyongyang on the Korean Peninsula was viewed as the capital of Makjoseon. First, let's consider the capital of Jinjoseon. As for the capital of Jinjoseon, Shin Chae-ho was called Harbin, and Choi Dong was called Haesung and near the nursing home in the current Liaodong area. Looking at the capital of Jinjo Line, it was said in <Hanseo>, "Gaemasan Mountain is on the west side of Pyongyang Castle, and Pyongyang Castle refers to Wangheomseong Fortress." Here, Gaema-hyeon was located in the current Haeseong Fortress and is also called Gaemaseong Fortress. In other words, Pyongyang Castle here refers to the sea castle in Liaodong, and refers to the capital of the Jinjoseon Line. In "Yosa Jiriji", "The nursing home was originally the land of Joseon..." It means that Pyongyang was in the current nursing home, where Yu Je-mu dispatched envoys to live in Pyongyang Castle. In other words, these records show that the capital of Jinjoseon was near Haeseong and nursing homes, which are fluctuating regions. Second, looking at the capital of Beonjoseon, Shinchaeho Lake was called Gaepyeong-hyeon (northwestern part of the Yodong Peninsula), and Choi-dong was called Gwangnyeong-hyeon (upper part of Daeneung in the Yoseo region). Then, we will consider where the capital of Beonjoseon appears in the literature. There is a specific record of mentioning the capital of Beonjoseon, and Seo Chang commented in "Sagi" and said, "There is Humdokhyeon in Changnyeo." Changryo is today near Galseoksan Mountain in the Yoseo region, that is, near Sanhaegwan. However, since "Sagi" said, "There is Humdokhyeon in Yodong, but it is the old capital of the Joseon Dynasty." Like the upper comment, if Humdok was the current Yoseo, Humdokhyeon was in Yoseo, and Beonjoseon was located in Yoseo, so it is highly likely that Humdok was the capital of the Joseon Dynasty. In other words, the fluctuation referred to in "Sagi" is today's Yoseo, and it means that Humdokhyeon is also in Yoseo. Looking at the records of the Han Dynasty, it was said in "Hanseojiriji" that "Wangheomseong Fortress is on the east side of the defeat of Nakrang-gun." If so, if the Wangheumseong Fortress in "Hanseojiriji" is Humdok, it means that there is Humdok in the east of the defeat, and because Humdok is said to be in Changnyo, the defeat here refers to Nanha. As we have already seen, if we look at defeat as orchids until the Han Dynasty, it means that Wangheomseong Fortress is on the east side of the orchid. Among the records after the Han Dynasty, Tongjeon, the record of the Tang Dynasty, said, "Wiman Bay's capital, Wangheom, is on the east side of defeat," indicating that the capital of Beonjoseon and Wiman Bay matched. There is Humdokhyeon in Changnyeo, and when Humdok is called Wangdok, the defeat becomes difficult, so it can be seen that Wangdok, the capital of Wiman Bay, was also in Yoseo. In addition, in the record of "Huhanseo", "Yangpyeong is a prefecture, but it belonged to Yodong-gun." It is recorded that the old castle is now in the southwest of Noryeong-hyeon, it is recorded. Since Pyeongju was near Changnyeo, and Yangpyeong refers to Pyongyang, or Wangheomseong Fortress, it is evidence that Yangpyeong was located in today's Yoseo region, and it can be assumed that the capital of Beonjoseon was located in Yoseo region. However, the Daecheong Il Notice, a record from the Qing Dynasty, supports Choi Dong's claim that the capital of Beonjoseon was in Gwangnyeong by saying, "The old castle of Humdok was in southeast Gwangnyeong-hyeon and belonged to Yodong-gun during the Han Dynasty." Gwangnyeong-hyeon Island is also located in the Yoseo region, and is located in the mid- to upper-middle area of Daeneungha. In other words, it can be seen from this record that Yodong-gun was also a Yoseo region at the time. However, it seems that the Humdok of the Gwangnyeong region was a temporary capital that took away the capital of the Changnyo region and moved to the east when Beonjoseon was invaded by Jingae of the Yeon Dynasty. Third, we will consider the capital of Makjoseon. As for the capital of Makjoseon, both Shin Chae-ho and Choi Dong agreed that it was Pyongyang on the Korean Peninsula. Since Makjoseon was far from China, it does not appear well in Chinese literature, so it can only be examined with the literature remaining in Korea. In "King Ungi", it was said, "Mahan's Wanggeomseong Fortress is now Seogyeong." Seogyeong at that time refers to Pyongyang now and is the capital of Makjoseon before the Later Three Kingdoms Period. There is also a phrase in "Samguk Yusa" that suggests that the capital of Mahan was originally Pyongyang. "Hanhan was named after Maeupsan Mountain in Pyongyang." This means that Mahan Mountain in Pyongyang was named after Mahan because it was the center of Mahan, which suggests that Mahan's original center was the present Pyongyang. In this way, Gojoseon was implementing the three economic systems as claimed by Shin Chae-ho, and considering Gojoseon as a country under a system, it cannot be solved for the capital of Gojoseon, which appears in various places. Seventh... There are records in the literature that before Jinhan and Mahan, the original locations of 韓韓과 and 韓의의, were moved south of the Korean Peninsula, Liaodong, Manchuria, and the North Korean Peninsula were the central areas. In general, academia tends to think or ignore these records as future errors. The territory of Jinjoseon (Jeonjin) and Makjoseon (Jeonhan) did not fluctuate much until they collapsed, and because they were far from China, the contents do not remain as abundant in Chinese literature as those of Bunjoseon (Jeonjoseon (Jeonhan). However, records indicating Jinhan and Mahan before being moved to the south of the Korean Peninsula are occasionally noticeable. First, let's look at the records that the original location of Jinhan was fluctuating and Manchuria before it was moved to the Korean Peninsula, and let's look at the area of Jinjoseon, which was advanced in a natural way. Regarding the area of Jinjo Line, Shin Chae-ho said that the northwestern part of Bongcheonseong Fortress is bordered by Yoha to the west and the southern end of the Yodong Peninsula to the south via Gilin, Heukryong, Yeonhae, Nongan, Jangchun, and Bongcheon. Since Jinjoseon is the presidential state of Samhan, it can include the areas of rule, such as Beonjoseon and Makjoseon.

An expression of the realm of Joseon with such a concept appears in "The Emperor Ungi". " The eastern land, including Sanhaegwan, and the eastern part of the Daeheung-Ansanmaek Mountain Range, developed and survived, so it was all the lands of the Eastern Kingdom and the boundary of the land under Joseon's jurisdiction. " Here, Dongdaeguk is an expression of "Siu," a combination of "Si," which means the east, and "Woo," which means great, in Chinese characters, and is written as Sayuguk and refers to Jinjoseon. When the meaning of presidential rule is combined with Jin, it becomes Siwoojin, and Siwoojin is said to be Jusin, Joseon, Suksin, Siksin, and Yeojin in Chinese characters. Here, Sanhaegwan is located on the east side of Nanhaha Stream, and the Daeheungan Mountain Range is a mountain range that crosses the northwest of Yoseo. In other words, it is said that Jinjoseon, the Eastern Kingdom, had jurisdiction over Yoseo (the location of Beonjoseon), located in the eastern part of the Daeheung Ansan Mountain Range, bordered by Nanha. In addition, in the same book, Dangun lived in Joseonseong Fortress and became the king of Goshira, Gorye, and the north-south Okjeo. Dongbuk Okjeo, Ye and Mac were all under the jurisdiction of Dangun." Goshira refers to the current Gangneung, and Gorye refers to Gyoryo, or Changnyeo, and Namokjeo and Bukokjeo refer to the Liaodong Peninsula and Seogando provinces, respectively. In addition, Mac refers to Beonjoseon, so it can be said that Dangun's ruling areas are Yoseo, Liaodong, Manchuria, and the Korean Peninsula. However, there is a record that tells the territory of Jinjoseon Bay, so "Bokju was the boundary of Joseon during the Zhou Dynasty, and Yeonghae was the boundary of Joseon during the Zhou Dynasty, and Yeonghae was the boundary of Joseon during the Zhou Dynasty." It's a phrase that says " Both Bokju and Yeonghae are in today's Liaodong Peninsula. In other words, the boundary of Joseon referred to here is the boundary with Byeonhan (Bunjoseon). From this record, it can be assumed that the western boundary of Jinjin (Jinjoseon) was important today. In addition, the same book said, "Gaepyeong-hyeon belonged to Joseon during the Zhou Dynasty, but it was originally dark land. He said, " Since Gaepyeong-hyeon is located in the northern part of the Yodong Peninsula, it can be seen that Yodong was also an area of Jinjin (Jinjoseon) during the Zhou Dynasty. There is another phrase that tells us that Goguryeo's Gaemoseong, or Jinju in the past, was the territory of Jinjoseon. Jinju, originally located in Gaemoseong, Goguryeo, was changed to Gaeju, and then to Jinju and was called Jinji Land. It's a record of ". Gaemoseong Fortress in Goguryeo is located in the northern part of the current Yodong Peninsula, suggesting that Yodong was the center of Jinhan before examining the authenticity of this record. A similar phrase is shown in the Bible Notice. " Originally, Goguryeo Gaegalmoseong Fortress was changed by Tang Tae-jong to Gaeju, and it was also changed to Jinju, so it was called Jinhan Land. " Here, it is also said that Goguryeo's Gaemoseong (or Gaegalmoseong), that is, the current sea castle, was later changed to Jinju, and that place was called Jinjin. Although this is a record written by a later mistake, it can be assumed that the original dark land was outside the Korean Peninsula, such as Liaodong, not the Korean Peninsula. The place names shown in the literature so far, namely, today's Geumju, Bokju, Gaepyeong, and Haesung, were all in Liaodong, indicating that the center of the Jinjoseon Line was the Liaodong Peninsula. In addition to fluctuations, there is a passage that tells us that Manchuria, such as Harpin and Nongan, and Buyeo in the old days were also the territory of Jinjoseon, and Buyeo in "Yosajiriji" made thick land (territory land). " is a record. It shows that Buyeo took place in the land of Jinjin (Jinjoseon), and through the fact that Buyeo was in Manchuria, it can be seen that Manchuria was also in the area of Jinjin. Second, there are not many documents related to Makjoseon, that is, Mahan during the Warring States Period, because Makjoseon was separated from China and the period when the Korean Peninsula entered the historical era in earnest was a prosperous period. However, there is a record indicating that Mahan was originally not the south of the Hangang River, but the north of the Hangang River and Pyongyang of the Daedong River. "Mahan" is named after Maeupsan Mountain in Pyongyang. "It's a record of Rahan. This phrase suggests that Maeupsan Mountain in Pyongyang was originally the center of Mahan. Jamhwaryu Book tells the approximate area of Makjoseon. " Hwanghae-do and Gojoseon are the old lands of Mahan. It's a record of ". This is from the central view of the peninsula that Gojoseon was on the Korean Peninsula centered on Pyongyang, but it was recognized that the central area of Mahan was the Yellow Sea south of the Yalu River and north of the Hangang River. From these records of Jinhan and Mahan, it can be seen that before the Hangang River was moved to the south, Liaodong, Manchuria, and the Hangang River were the central areas. The eighth...The problem faced by the former territory of Korea Last time, the realm of Jinhan and Byeonhan was proved, and today, before the realm of Jeonbyeonhan (Bonjoseon), let me tell you the problem faced by the realm of Beonjoseon. In short, it is difficult to pinpoint the area of Beonjoseon. This is because Beonjoseon was connected to China, and its area changed with the times according to the rise and fall of China. In addition, numerous small countries and ethnic groups entered China in Beonjoseon (Mac). Most of the struggles of the Ha and Yi tribes seen in Chinese literature during the Hanara period were related to the Beon Koreans, and strictly speaking, it can be said that it was also related to Jinjoseon because Beonjoseon was a jurisdiction of Jinjoseon. Beonjoseon has been marked in various ways in Chinese literature, including Mac, Mac, Mak, Bak, Bal, Yemaek, Bakmaek, and Gumaek. Looking at a recent study related to the Maek people (Bunchon Koreans), first, most of the origins of the Dongi people active in eastern China are based in the northeastern part of China (Habuk, Yoseo, and Liaodong), and second, all of these Dongi people are deeply related to the Maek people (Bunchon Koreans) and Jinguk (Jinjoseon). From these research results, it can be said that the area of Beonjoseon was also related to the Dongi tribe or the Macs who were active in eastern China until the time of the Silver Dynasty. If so, it means that the eastern part of China, such as Habuk and Shandong, the western regions of Nanha and Baekha, was also considered the territory until they were expelled to Nanhai-dong by the Qing Dynasty. This is because until the Zhou Dynasty implemented the feudal system and moved the western empires to the east, the Dongi or the Macs were active in the eastern regions of China, such as Habuk, Shandong, and Gangso. In other words, until the Zhou Dynasty moved empires such as the Qian Dynasty, the Yeon Dynasty, and the No Dynasty from the western inland region to the east, it was an active stage for the Dongi people. In the process of the movement of the Zhou dynasty, struggles with the same people are seen in the literature, and the same people are gradually pushed back to the Yoseo region, northeastern China. Here, such the activities of the same clan were viewed as the areas of the activities of the Bunchoseon people, and in proving the areas of Bunchoseon (changed), they will be classified by period as follows. First, the area of Beonjoseon during the reign of Hana Eun Dynasty, the area of Beonjoseon before the invasion of Jingae in the Yeon Dynasty, and the area of Beonjoseon after the invasion of Jingae in the Yeon Dynasty were adjacent to China, so there were many changes in area. Next, we will consider the area of Beonjoseon before the invasion of Jingae in the Yeon Dynasty, which is clearly recorded in the literature. Re: ...I referred to such things. I can say that there are many things. It's a Korean book by Kim Jungbae.Choi Dong, <National Origin and Formation of Korea Ancient Era> Shin Chae-ho, <Chosun Sanggo National History> and <Chosun Sangosa> Lee Man-yeol.<Korean History> Moon Jeong-chang <Korean History Research> Cheon Kwan-woo.<The Formation of the Nation of Samhan> Jeong In-bo. <The Study of Joseon History> Yun Nae-hyun <Theology of Ancient Korean History> Lee Seong-gyu <The Culture and Trends of the East Central Stage> Lee Byung-do <The History of Samhan> Chinese literature> Daecheong Ilji Yeomcheolji, Tongjeon Samgukji.<hereinafter referred to as East-West Theory> Heo Heon-beom <Nationality and Culture of Ancient Northeast Asia> Oh Yeo-jo <Oriental Culture Collection> Ko Gwang-in <Shandong Dictionary Culture Collection> Eom Mun-myeong <Dongi Cultural Collection> Ahn Geum-mog <Shi Ha Yong-san Culture> Jingwang <Anti-Hak Culture Collection> Hwang Joong-yeop> Here, Chinese literature and Chinese scholar books are excerpts from what they refer to as a group of ancient Eastern family-related history or mentioned in research papers by other scholars. Among my papers I wrote in 1996, there was a review of my problems related to Jeon Sam-han, but I can't think of it well because I'm going to write it after five years. I'll refer to the above literature a lot when I mention it in the future. And if you read the contents, you will see that it is similar to Korean short-term meat. However, it is revealed that the short-term meat was not referenced. Personally, while studying this argument, I found that the content of Korean short-term meat was quite reliable, regardless of whether it was a consolation or not.
