Many people have made a detailed comparison between Goguryeo and Goryeo, and the conclusion is very clear. The two are different in terms of origin, geography, ethnicity, history, politics, customs, etc. The ancients were very strict in writing, and "Guryeo" and "Goryeo" had nothing to do with each other, but some people in the Central Plains were similar in pronunciation and both in the Northeast, so they subjectively thought that the two were the same. Summarizing the Book of the Later Han Dynasty, the Chronicles of the Three Kingdoms, the Northern History, the History of Goryeo and related historical materials, the following results can be obtained:
The accurate name of Juli should be "Gao's Juryo". It is also called Gou Lou, and Gou Lou, 貊, Da Shui and so on. About 130 B.C. (Western Han Dynasty), a good shooter named Gao Zhumeng from Fuyu Kingdom, with Gao as his clan, founded a country in the northeast of Susheng Bone City. Their kingdom was in the northern section of the Songhua River and to the south, and they claimed to be the sons of the sun and the grandsons of Hebo (from the Book of the Later Han, the Chronicles of the Three Kingdoms, and the Northern History). Fuyu Kingdom is from Gu Suo Liguo, from Gu Xishen, and is a descendant of Emperor Yan. Therefore, the country of Juli must also be a descendant of Emperor Yan, believing in the sun and fire, and advocating red. The kingdom of Juryo originated in the northern part of the Great Plain of the Northeast and developed from north to south in the central part of the Northeast. After several ups and downs, it fought tenaciously in the Northeast, and at its peak, it almost occupied the northeast and the northern part of the Korean Peninsula, which lasted about 800 years.
"Book of the Later Han Dynasty" contains: Juli "is said to think that the husband is more than another species", and also said: "Juli is a husband, and there are other kinds of living according to Xiaoshui, because of the name Xiaoshui". Therefore, the Gyeo people are the people of the country, which is different from the Koreans in the southern part of the Northeast.
"Chronicles of the Three Kingdoms" contains: "Those who ditch Lou, the famous city of Juli", "Juli is a country, and lives according to the water,...... The other species of Guree are based on small water as a country". Thereinto:
The word "sentence", "Kangxi Dictionary" has an explanation of: "sound ditch, vulgar hook, song also". In the dictionary, the word "ditch" is: "water sound", which also means a small river. Obviously, whether it is a sentence or a ditch, it is a gurgling and crooked flow of water here, which indicates the characteristics of the place where the people of Juli lived.
The character "Lou" is also a common name used by Northeast Chinese people in ancient China. In the "Kangxi Dictionary": Lou - the horse cow is called Lou Ma Niu, which means the majority; It is also the name of the Northeast place, the name of the river, the surname, the name of the stars, etc.; In addition, "Lilou" is the one who is clear-eyed, and it also has the meaning of small and micro.
The original meaning of the word "Li" should be the word "Li", which is the sound "Li" often made in the end of the discourse of the ancient Northeast people in the mainland, so the Northeast people commonly used this word when they founded the country, such as: Suo Li, Tie Li, Ju Li, Gao Li, etc. In the Chinese innate eight trigrams, the east is "li", which contains the following contents: fire, sun, beauty, gorgeousness, samurai, red, for... And the northeast belongs to the east in the ancient map, not the northeast. Most of the people here believe in the sun and fire, so the word "li" is a script that the people of Northeast China are willing to use.
By 668 A.D. (the first year of the general chapter of Tang Gaozong), Juli was destroyed by the Tang Dynasty.
The surname of the king of Juryo was "Gao", and before and after the founding of the People's Republic of China, until the destruction of the country in Jureo, it has always been dominated by the area north of the Yalu River. Only after the prosperity of the country, it occupied a large area of land south of the Yalu River to the north of the Datong River. But this land has been one of the inseparable territories of China since ancient times. During the Sui and Tang dynasties, the capital of the country began to move to the vicinity of present-day Pyongyang, North Korea. However, unlike Silla and Baekje on the peninsula at that time, they have always been an integral part of the Chinese nation, and they are one of the 100% ancestors of China.
A large area of land south of the Yalu River was a natural part of China from ancient times to the Qing Dynasty. After the fall of Jureo, the Bohai Kingdom, the Liao Kingdom, etc., all occupied this place. Later Goryeo wanted to occupy it, but the Liao Dynasty did not give it to them, and the Jin and Yuan dynasties were in turmoil, and this land still belonged to Huaxia (at that time, Later Goryeo and Later Korea both belonged to China).
Although the Juryo Dynasty was in the late Northern Wei Dynasty, when she was the Empress Dowager Ling, she was canonized as the "King of Goryeo" by the Northern Wei Dynasty. After the fall of Guryeo, the last king, Gaozang, and his descendants were also canonized as "King of Joseon" by the Tang Dynasty for a period of time. But their main jurisdiction is not on the Korean Peninsula, but in the Liaodong region in the southeastern part of the northeast. Especially after Gaozang, the area under its jurisdiction was only a territory within the jurisdiction of the Tang Dynasty, all in the eastern Liaodong region, and did not cross the south of the Yalu River. Gao Zang became the governor of Liaodong and the king of Joseon, and began to rebel when he returned to Liaodong New Town (now southern Fushun, Liaoning Province) from the Tang Dynasty. Before he could have a seizure, he was re-recruited by the Tang Dynasty and placed in Qiongzhou (now southern Sichuan Province) until his death. The Tang Dynasty buried Gaozang on the east side of the Jieli Tomb. Jieli was a Turkic khan who was captured by the Tang army and died in the Central Plains for violating the Tang border.
The historical information of the Goryeo Kingdom is more detailed, and it was founded in 918 AD (the fourth year of the reign of Emperor Zhenmyeong of the Later Liang Dynasty) by the Silla king in the northern part of the peninsula south of the Yalu River. This area was once a pure traditional area of ancient Goryeo (ancient Korea), Samhan, and Silla. The post-Goryeo people are descendants of the purely traditional ancient Goryeo (ancient Korean). Before the demise of Guryeo, the ancient Goryeo people had experienced a transitional stage between Samhan and Silla. In the later period of Guryeo's existence, it corresponded to the kingdom of Silla, but Silla was squeezed by Guryeo to occupy only a part of the southeastern part of the peninsula.
For 250 years from the demise of Go's Guryeo to the establishment of Wang's Goryeo, it was mainly the territory of Silla. Although in the late Goguryeo period, especially before its demise, some Goguryeo people may have fled here. However, because Guguryeo and Silla had a feud, and at that time, Silla and the Tang Dynasty allied together against Goguryeo and Baekje. Baekje, located in the southwest of the peninsula, had already been destroyed and occupied by the Tang army three years before the fall of Guryeo. Therefore, it is very unlikely that the Goguryeo people fled to the south of the peninsula, and even fewer people should have gone to Silla. Even if some of the Guryeo people fled to Silla and the Tang Army-occupied areas, they would never become the mainstream of the people here. The people who live here are mainly the indigenous ancient Koreans, Samhan, and Silla. Therefore, it is extremely unlikely that the Goryeo Kingdom of the Wang clan established by some Silla people has elements of the original Juryo people. In other words, among the ethnic groups of the Goryeo people, it is impossible for the ethnic group of Haraguryeo to exist.
The hometown of Baekje in the southwest of the peninsula, although Baekje and Gureo have the same roots, was completely controlled by the Tang Dynasty army at that time. The Tang army occupied this place only to fight against the Guryeo, and it was impossible to allow the perished Guryeo people to gather in this direction. Therefore, when the Juli people perished, there was basically no possibility of fleeing to the southwest of the peninsula. Both, in this direction, it is also impossible to appear in the Guryeo.
The southern part of the Korean Peninsula, after the fall of Baekje and Guryo, was filled by the Silla people, and finally became the land of Silla until the south bank of the Yalu River. However, after the withdrawal of the Tang army, Baekje was quickly revived, so the southwestern part of the peninsula was still controlled by Baekje. The northern part of the peninsula was soon occupied by the Balhae Kingdom, and Silla retreated to the southern part of the peninsula. By 918 AD, the state of Goryeo was established in northern Silla. In 935 AD, the Goryeo Kingdom completely destroyed the Silla Kingdom, and the following year destroyed the Baekje Kingdom and unified the Korean Peninsula.
Goryeo people, mainly from Silla. Silla came from Jinhan and Benhan, and its ancestral origin was the ancient kingdom of Chen. Guchen Kingdom is a branch of Gugoryeo (Gujizi Joseon), and Gujoseon is the place where King Wu of Zhou canonized Jizi as the Marquis of Goryeo. Jizi Joseon is also called Gugoryeo, and the people are mainly pure Koreans. Jizi Joseon was later captured by the Yan people Wei Man and became Wei Man Joseon. The descendants of the Minzi were hidden among the people with the surname Han and built Korea on the island. After the destruction of Weiman Korea by Emperor Wu of the Han Dynasty, the Koreans of the island country moved to the Korean Peninsula and became the later Koreans, namely the Samhan (Mahan, Jinhan, and Benhan) people.
Books such as "Book of the Later Han", "Chronicles of the Three Kingdoms", and "Northern History" all say that during the Weiman Joseon period, the state of Guryeo was established in the northern part of ancient Korea (ancient Goryeo). Therefore, the fact that ancient Korea and the state of Guryeo once existed in the present-day Northeast region at the same time fully shows that they were two different countries.
From what was said above, North Korea is from Wang Jian, and Wang Jian is a descendant of Changyi, the second son of the Yellow Emperor. So Gujoon (Gogoryeo) is also a descendant of the Yellow Emperor. By 108 BC, Emperor Wu of Han destroyed Korea. When Korea was divided into four counties, Xuansu, Lelang, Lintun, and Zhenfan, the state of Juree was not wiped out. Instead, it was set up as Juli County by Emperor Wu of the Han Dynasty and placed under the administration of Xuansu County, which was still led and managed by the former Gao family group in their own region.
Goryeo, which was founded in 918 AD, destroyed Silla in 935 (the second year of Emperor Cheongtae of the late Tang Dynasty) and Baekje in 936 AD (the first year of Gojo Cheonbok of the Later Jin Dynasty), making the peninsula three into one. Since then, the Baekje people, the descendants of the Fuyu people, have been added to the Goryeo region, and the Han people, the Jin people, the Hao people, and the Khitan people have successively defected to the Korean region, and the Goryeo nation has become a large hybrid people mainly Koreans.
Until 1392 A.D. (the 25th year of Ming Taizu Hongwu), Li Chenggui destroyed Wang's Goryeo, established himself as king, and changed his name to Joseon. In 1393 (the 26th year of Hongwu Taizu of the Ming Dynasty), the Ming Dynasty made Li Chenggui the king of Joseon, legitimizing the usurping Li dynasty.
The name of Goryeo was not an original invention of the Silla king when he founded the country, but a new kingdom established more than 1,000 years after the fall of ancient Goryeo by taking advantage of the title of the ancient Jizi and the favorable condition that the Wang family was the ancestor of the ancient Koreans.
Unlike Goryeo, which is dominated by the central part of the Tohoku region, Goryeo never crossed the northern part of the Yalu River. It is a native of the Korean Peninsula and its customs and country, but its culture is 100% inherited from the Chinese nation.
The kingdom of Gogoryeo (ancient Joseon), especially during the Mija Joseon period, included the southeastern part of the Northeast and the Korean Peninsula, and even reached the southern part of Mt. Ikooroksan.
When the state of Juryo was strong, it included not only the central and eastern parts of Northeast China, but also the southern part of Northeast China and most of the northern part of the Korean Peninsula. Therefore, some people in the Central Plains are accustomed to calling "Goryeo" by the name of the place.
But:
Juli is a descendant of the Hui and Zang people, and originated in the north-central part of the Northeast.
Goryeo is a descendant of the ancient Koreans who originated in the central part of the Korean Peninsula.
Although there are duplications in the areas of activity of the two, especially the late King of Guryeo was once canonized as the title of "King of Goryeo" by the Northern Wei Dynasty, the difference between the two is decisive and cannot be confused.
