Goguryeo, the greatest power in Northeast Asia.

 What kind of country was Goguryeo? 1. A giant kingdom of 6,000 miles east-west. According to Suseo, one of the 25 history of China, Goguryeo's territory was recorded as "6 thousand ri from east to west." Six thousand ri east and west This means that the territory from east to west of Goguryeo is six thousand ri. As can be seen from the word 6,000-ri, Goguryeo was a huge kingdom that owned more territory than we thought. Considering the capital of Goguryeo, Pyongyang Castle (or based on domestic castle), it can be assumed that Goguryeo's territory reached south of the Great Wall to the east (Yoha, the lifeline of Goguryeo, is not the current Liaohe River, but the western boundary of Goguryeo can be seen as south of Taewon). In addition, according to Suseo and Goguryeojeon, it is surprising that it has been a long time since Goguryeo people secured large land from Balhae to Galseoksan Mountain in Yoseo region before the Goguryeo invasion. As such, Goguryeo was a giant kingdom that occupied more territory than we imagined. **The Sogu of Goguryeo was confused, so they were not polite, gathered groups in Balhae and Galseok Sushi, and encroached on the land of fluctuations and Yemaek. As the Han Dynasty and the Wei Dynasty repeated the conquest, the nest was disturbed for a while, and then the race huddled together and flourished like the beginning of a stream. "(Joongchak)-Yangje's record- *2. The image of Goguryeo, a rich economic power, comes to mind when it comes to the geographical location. Therefore, people think Goguryeo is a poor country with insufficient food. However, Goguryeo was not a poor country, but a rich economic power. Of course, at the time of the founding of Goguryeo, the surrounding area was a mountainous area, so they had to loot and feed on the surrounding villages and countries. However, after the constant expansion of Goguryeo and the foreign conquest of King Gwanggaeto Ho-tae, Goguryeo was no longer a poor country to loot and feed on the surroundings. After King Gwanggaetohotae's foreign conquest, Goguryeo became a rich country to the extent that it no longer suffered hunger by securing the plains of Liaodong, Yoseo, Pyeongan-do, Hwanghae-do, Hangang River, and Songhwagang River and Usuri River. Queen Hote recorded this situation as follows. Unlike the Joseon Dynasty, where the country was rich, the people were comfortable, and the five grains were ripe abundantly, Goguryeo greatly encouraged commerce. According to the History of the Three Kingdoms, there is a record that King Micheon of Goguryeo played a salt merchant when he was chased by King Bongsang. Salt is a country's resale and is prohibited from doing business by individuals and controlled by the state. However, in Goguryeo, salt sales were relatively free compared to other countries. Of course, the owners of salt farms that produce salt would have been aristocrats and countries, but the people who sell the salt would have been ordinary commoners such as Eulbul and Jaemo. The fact that individuals were able to sell salt shows that Goguryeo encouraged commerce. In addition, Goguryeo was interested in trade, such as installing bookcases in the border region with Han Dynasty at Gukcho to exchange supplies. In Goguryeo, where commerce was developed, there was a market. The existence of the market appears when you look at "Three Kingdoms History" and "Ondaljeon." From here, Ondal buys national horses sold in the country, and in Goguryeo, it can be seen that commerce was so popular that the state sold goods to the market. In Yuseong in the Daerungha basin, there was Goryeo Market, a large-scale international market. This is an international market where nomadic peoples, agricultural peoples, and hunter-gatherers from the north gather and trade on a large scale. However, according to the Suseo Yu Ungijeon, it is recorded that when the Sui Dynasty conquered Khitan, 20,000 soldiers disguised them as merchants going to the Goryeo market to reassure the rebellion and attack the rebellion to win. You can guess what the size of the Goryeo market was like so much that 20,000 disguised merchants were mistaken for trade groups by the Khitan people. Goguryeo, which recommended commerce, knew the importance of carts early and recommended transportation through carts. Carts are useful for moving loads in large quantities, which is a catalyst for the development of all social fields such as commercial development, urban development, and construction of huge buildings. The cart is the crystal of the scientific knowledge of the old people developed by today's cars and trains, and is also the same as the standard that characterizes civilization. Earlier, Park Ji-won mentioned the importance of carts in the History of the Year. If there is a means of transportation called carts, transportation develops, and supplies between regions also promote national wealth. Goguryeo encouraged carts, so it was possible to secure a nationwide distribution network, which helped strengthen its national power. With this commercial policy, Goguryeo was able to engage in tremendous trade with the Northern Wei, which is 200 geun of gold and 400 geun of white every year. 3. Not only did he like books, but he also installed large structures on all four streets, and he enjoyed archery while reading here day and night before his marriage. There were Ogyeong, Sagi, Hanseo, Bumyeop's Huhanseo, Samgukji, Jinchunchu, Okpyeon, Jatong, and Jarim. According to the records above "Gudangseo" and "Goguryojeon," Goguryeo people at that time were very academic that even ordinary people liked books. This shows that Goguryeo's education level was higher than that of any other country. When King Taejong sent a envoy to Goguryeo, he told Ju Ju Ju-sa, who was selected as a envoy, that the Goguryeo people had a very high academic level and valued their studies, and that the Goguryeo people's academic level was equal to that of Tang Dynasty people. This means that King Taejong recognized Goguryeo as a cultural powerhouse. In addition, many Han Chinese moved to Goguryeo to avoid the chaos of the Five Kingdoms Period, but many naturalized Han Chinese moved back to the midfield when the continent of Jungwon stabilized during the North-South Dynasties Period. However, as soon as they moved to the Middle East, they received high government posts. This shows that along with the breath of Goguryeo, they learned learning properly in Goguryeo and showed their advanced academic level without regret. In other words, it can be said that Goguryeo's academic level reached a considerable level at the time. High enthusiasm for learning... This can be said to be the driving force behind Goguryeo's maintenance of a powerful empire. Goguryeo's construction technique also had considerable skills. Unlike Chinese castles, Goguryeo castles were built using natural environments, and Chinese castles used bricks, while Goguryeo castles were built with stones, so they were able to defend firmly against enemy invasions. In addition, Goguryeo was built in a terraced manner when the castle was built to strengthen the castle. Goguryeo Castle is a defense facility, and representative facilities such as Chi and Ongseong were also installed. Among the walls surrounding the castle, Chi was advantageous when attacking enemies from all sides. Ongseong Fortress is a defense facility built by rolling the castle gate in a circle, and is a useful defense facility for trapping and annihilating enemy troops. Thanks to this construction technique, the Han Chinese evaluated Goguryeo as building a good castle and keeping it well. It can be said that the Sui and Tang kingdoms invaded Goguryeo earlier and failed to win because of the unique castle structure of Goguryeo. The murals of Goguryeo's ancient tombs show that Goguryeo is a civilized country with an outstanding cultural level. Usually, ancient murals are usually dewy due to the temperature difference from the outside of summer, and the walls are shiny and paint flows, so you cannot see their original appearance properly. In addition, lime painted on the wall often falls off and the painting itself disappears. However, many Goguryeo tomb murals, including the Tomb of Ohhoebun No. 4, maintain their original colors perfectly. This is impossible without scientific knowledge. Goguryeo tomb murals were painted using a fresco technique, and thanks to these techniques, Goguryeo tomb murals could remain to this day without losing their original color. This shows that Goguryeo people's mural processing technology possessed the world's best technology of the time. The mural, which is considered the most outstanding of Goguryeo's ancient murals, is definitely a Sashindo mural. The envoy is the guardian deity of the four directions of east, west, north, south, and west of Cheongryong in the east, and is a basalt in the north of Jujak in the south. The Sashindo Ancient Tombs are well-known for their excellent vitality and colorful colors, and their artistic value is very high. It's not just that. Goguryeo was a science powerhouse with excellent astronomical observation techniques. The Cheonsang Train Field Map depicting the sky of the Goguryeo period is said to be an astronomical map depicting the sky of a domestic castle around the 1st century AD. It is a record indicating that Goguryeo people possessed astronomical observation techniques that were so outstanding that they doubted whether such astronomical observation was possible at that time. It is said that there was an observatory in Goguryeo in "Pyongyangbu" in "Geography of the Annals of King Sejong." In addition, astronomical management related to heavenly observation existed as the date. The development of astronomy enabled Goguryeo people to sail offshore, travel long distances on grasslands or continents, greatly contributed to the development of agriculture and fishing, and also contributed to enriching the spiritual world of Goguryeo. Goguryeo's astronomy spread to Baekje, Silla, and Japan, and had a great influence on later generations. As such, Goguryeo was a great empire with an outstanding civilization that surpassed China.

Therefore, Dr. Kim Yong-man, a researcher in Goguryeo history, once described Goguryeo as a civilized nation. 4. Another Chinese and Heavenly Kingdom Goguryeo with its own view of the world! Goguryeo was almost the only country in our history with its own view of the world. (According to Handango, which is not recognized as an official librarian by the domestic Gangdan history community, Cheonja and Cheonson are Korean people, and Gina stole the concept of Cheonja.) Goguryeo's great conqueror Gwanggaeto Ho Taewang  It means that Goguryeo's affiliation is not a local government of the Jungwon Dynasty, but Chinese historians who are currently distorting Korea's ancient history by promoting Northeast Gongjeong ignore even basic common sense. If you look at the old records of Handango, it is written that Goguryeo used the name from Gukcho. When you look at the Queen Ho Tae, the son of King Gwanggaeto Ho-tae, who was founded after the death of King Jang Su-tae, the Yeonho of King Memorial, the Goguryeo people call themselves "Cheon-son," which means descendants of heaven, and is like the Chinese heavenly son. In addition, the founder, King Seong, is expressed as Cheonjeja and Ilwolja, literally referring to Cheonja, the son of God. The Goguryeo people believed that King Tae, the monarch of Goguryeo, ruled the world under the command of heaven. In addition, there is a part that the power of King Gwanggaetohotae was in the Dead Sea, where the Dead Sea can only be used by the Chinese Heaven, and Goguryeo's use of the expression Dead Sea means that Goguryeo is heaven. If you look at the name of Moduru Myoji, it can be said that Goguryeo shows Goguryeo's view of the world well by describing it as "the holiest place everywhere in the world. Looking at the Jungwon Goguryeo Monument, Goguryeo describes Silla as Dongi, which gives a glimpse of Goguryeo's central view of the world, which sees neighboring countries as orangkae centered on Goguryeo. According to the Joseon Sangosa written by Danjae Shin Chae-ho, it was recorded that Goguryeo is called Gauri in pure Korean, and Gauri means Jungang, Junggyeong, and China. Goguryeo's view of the world differs from that of China's view of the world, while China showed a narrow and closed appearance that only recognized its view of the world, Goguryeo had the idea of coexisting with that of other regions along with its own view of the world. Goguryeo viewed the entire East Asia, consisting of the first worldview, which is directly controlled by Goguryeo, the second worldview, including Goguryeo's subordinates, and several parallel worlds, as the third worldview. In other words, Goguryeo shows a pluralistic appearance that recognizes the view of the world in other regions while establishing their own view of the world. Therefore, Goguryeo, which has openness, not a closed Chinese view of the world, can be said to be a heavenly nation with a true view of the world. 5. Goguryeo, the largest military power in ancient East Asia. Goguryeo was not only the largest territory in our history, but also a military power with powerful military power. Goguryeo was a heavenly kingdom that dominated East Asia based on its strong military power. Goguryeo's founding place is today in Nammanju, where there were basically many mountains and insufficient plains. Therefore, Goguryeo looted the surrounding area early to supply food. This can be seen as similar to the flow rate of the ancient nomadic peoples. Goguryeo showed off its strong national power from the beginning of the country, and Han Dynasty, a neighboring country, was in a hurry to please Goguryeo by allowing trade in Bookguru. King Daemushin, the third king of Goguryeo, conquered Nakrangguk, the empire of Dangun Joseon, and Buyeo, a powerhouse that dominated the northern Manchuria area at the time, and attacked King Movon, the fifth king of Northeast Asia. According to the History of the Three Kingdoms, "In the spring of the second year of reign, the king mobilized the great army to attack Han's Bukpyeong, Eoyang, Sanggok, and Taewon. It is recorded that Liaodong Taesoo Chae-dong treated them with silver and good faith, so they became friends again." According to this record, it shows that Goguryeo was strong enough to attack Han at the time. However, these areas were very far from the Dongga River basin, the center of Goguryeo, and Goguryeo was able to raid and occupy this area, indicating that Goguryeo had a powerful equestrian corps (Gamamu Private) at that time. According to the History of the Three Kingdoms, it is recorded that during the 8th King, King Sindae, "Huhan led the great army and invaded, but Myeongnim Dapbu defeated Han's army in the left, so no one could survive." This record can be said to be a record that can gauge Goguryeo's national power at the time. The official name of King Gwanggaeto Hotae, who achieved the heyday of Goguryeo, is King Gwanggaeto Gyeongan Hotae, meaning "the great king who greatly expanded the territory of the country buried on the Gukgang River and made the people peaceful." Like King Gwanggaeto Ho-tae pioneered territory in all directions and occupied Siberia in the north, East Mongolia in the northwest, Maritime Province in the east, Hangang River in the south, and Yoseo and Yellow River basins in the west. His son, King Jangsu-tae, made Goguryeo stronger. King Jangsu-tae took advantage of the international situation at the time to develop Goguryeo's national power. Around the 5th century AD, Goguryeo's strong period, Jungwon was divided into the northern latitude in the north and the southern latitude in the south, and there is a record indicating that the northern latitude, which boasted a powerful national power, was stuck in Goguryeo. ① Goguryeo gave the genealogy of the northern royal family, and at the request of Goguryeo, the northern royal family gave the genealogy of the northern royal family to Goguryeo. In general, the genealogy of a country's royal family is the country's historical book, and the country that can dedicate the country's historical book is an act that only the country's upper country can do. During the Warring States Period, the reason why the Ju royal family was able to receive genealogy from various empires was because the country's upper kingdom, that is, the Zhou Dynasty, was the Heavenly Emperor of the Middle East. However, Goguryeo's demand to dedicate the genealogy of the northern royal family and the Northern Wei's offering of the royal genealogy suggest that Goguryeo's national power was stronger than that of the northern Wei at that time. ②When King Jangsu-tae died, Gojo of the Northern Wei wore a so-called white hat and four-seam and went to the eastern suburbs to express his condolences, and King Sejong of the Northern Wei built a shrine called Goryeomyo, where Goguryeo's founder was held in 508. When King Muyeol of Silla died, King Gojong of the Tang Dynasty held mourning, but even built a shrine and the king did not practice it himself. No country in the middle of the country wore mourning clothes because the king of another country died, and there was no case where the king directly organized the mourning ceremony and built a shrine where the founder of another country performed ancestral rites. Likewise, Goguryeo has never worn mourning clothes directly even if any king in the midfield died. How should we accept the fact that the Northern Wei, which was powerful in the North-North Dynasties period, provided Goguryeo with examples of a new kingdom? We didn't know the glorious fact. Through these fragmentary records, we can take a step closer to the true face of Goguryeo. Do you happen to know? If this record is true, Goguryeo is a tremendously powerful great empire and a kingdom of heaven that used the Jungwon Dynasty as a subordinate country......6. Goguryeo, the center of the world. It is the victory of Suyeo Daejeon and Dangyeo Daejeon that prove that Goguryeo, the Suyeo Daejeon and Dangyeo Daejeon, are the powers that will shine in the history of world war. The Su Dynasty, which unified the midfield, invaded Goguryeo with an unprecedented great army in history, but was rather defeated by Goguryeo's war of war, and the Tang Dynasty also invaded Goguryeo, but had to taste the bitterness of defeat several times. In particular, Su's expedition to Goguryeo caused the collapse of its own country, so in a way, it can be said that Goguryeo destroyed the Su Dynasty. The invasion of Goguryeo by the Su Dynasty was a phenomenal event. This is because as many as 4 million people were mobilized to hit the country called Goguryeo. With 4 million people, this number was about a tenth of the total population of the Jungwon at the time, indicating that the Su Dynasty at that time devoted all its efforts to attacking Goguryeo. However, the first battle of Suyeo Daejeon began with Goguryeo's invasion of Yoseo. The Suhwang issue, which unified the midfield, sent an arrogant national document saying that the Su Dynasty was incomparable to Goguryeo, so it should surrender quickly, and King Yeongyangtae, then king of Goguryeo, accepted General Kang Yi-sik's command and attacked 60,000 troops. We knew Goguryeo as a passive country that had always defended itself. However, this is due to wrong history education. In fact, Goguryeo was not a passive country only defending, but rather an active country with the ability to attack the enemy.(This can be seen from King Mobon's invasion of the Han Dynasty.) With 1.13 million soldiers, Emperor Yangje, who invaded Goguryeo, surrounded Yodongseong Fortress, a key point of Goguryeo. However, when Goguryeo's defense was excellent like an iron wall and could not be captured, Umunsul and Ujungmun were called in to give 300,000 stars to attack Pyongyang, the capital city of Goguryeo. In the Battle of Salsu, where Goguryeo defeated 300,000 troops from the Su Dynasty, there is one fact that we overlook. In fact, the brilliant victory of the Battle of Salsu was possible because there was a victory over the Paegang River (the Daedong River in academia, but considering various books, the Paegang River was not the Daedong River, but the Liaohe River tributary). What is the Battle of the Fallen River?

This battle is a battle in which Nae Ho-a, the naval governor of the Sui Dynasty, was defeated by Goguryeo naval forces led by Wang Je Geon-mu in the Paegang River. Due to this battle, the naval forces of the Su Dynasty fell into a state of inability to comeback and could not provide food to Byeoldongdae (300,000 troops) of the Su Dynasty led by Wu Mun-sul, which caused Byeoldongdae of the Su Dynasty to suffer from hunger. General Eulji Mundeok, who saw through the situation of the Su Dynasty's troops, engaged in seven battles and lured the Su Dynasty soldiers to the vicinity of Pyongyang Castle and attacked them at Salsu, and about 2,700 of the 300,000 troops died alive. This is the Battle of Salsu, which shines in Goguryeo's war history. We understand that General Eulji Mundeok's transmission of the Battle of Salsu is the one. Of course, the major of General Eulji Mundeok is so great that the Salsudaecheop would not have been achieved without General Eulji Mundeok. However, it is wrong to see the protagonist of the Salsudaecheop as a general Eulji Mundeok. In the Battle of Salsu, there was another hidden protagonist, which was the king Geonmu. Due to the defeat of Geonmu, a brilliant warrior called the Battle of Salsu was able to emerge. Danjae Shin Chae-ho commented on the victory of the Battle of Salsu as follows. "Goguryo already took the position to win at this time (the battle of defeat by Gunmu) that destroyed Naehoa's naval forces), so if it were to take the turn of the major, it would be said that the king Geonmu was ahead of Eulji Mundeok. Although King Geonmu's contribution has been so great, what kind of connection does it mean that people who read history often only know Eulji Mundeok? According to the Tonggamgoi of Samaongong, it is usually right that there would have been no defeat in the sprinkling of Umunsul if Hoa had not lost his aquaculture boat." As Danjae pointed out, the sprinkling battle is not the only major of General Eulji Mundeok. That doesn't mean that Geonmu's ball is all the more. The majors of the Salsudaecheop can be said to be the majors of General Eulji Mundeok, General Geonmu, and all Goguryeo people who wanted to protect the country. Without the Goguryeo people's love for the country, if Gunsin Gwan-min had not united, without General Eulji Mun-deok and General Geonmu, Goguryeo's brilliant victory would not have been achieved. The Su Dynasty was defeated in the repeated war against Goguryeo, and the morale of the people was reduced due to excessive Goguryeo expeditions, and to make matters worse, the Su Dynasty collapsed more than 30 years after its foundation and the warring era in Jungwon. If Goguryeo had not missed this opportunity, it would have been able to enter Jangan and become the loser of the midfield. Personally, it is regrettable that Goguryeo missed this opportunity. It was Gojo Lee Yeon, who founded the Tang Dynasty, who unified the midfield in the chaos of the Joseon Sangosa Temple by Shin Chae-ho Co., Ltd., who unified the confused midfield with the performance of his son Lee Se-min and opened the Tang Dynasty. At this time, King Goguryeo was crowned King Yeongryutae after King Yeongyangtae, the main character of the Battle of Paegangseungjeon. Unlike the spirit of defeating the Su Dynasty in the past, King Yeongryutae pursued a safe route against the Tang Dynasty. He tried to avoid conflicts with the Tang Dynasty as much as possible, paying attention to the restoration of the Liaodong region devastated by the war. The Tang Dynasty also did not pay attention to Goguryeo because it was in the early days of its founding, but they were aiming for Goguryeo, just like in the Sui Dynasty. King Yeongryutae, who does not know what the Tang Dynasty is thinking, conducted humiliating diplomacy as the Tang Dynasty wanted, drawing complaints from the warriors, and further gave up the policy of Namsubukjin, Goguryeo's traditional policy, and advanced to the north, protecting the north. It has been changed to a policy. King Yeongryutae's policy caused complaints from the non-class, and in particular, the opposition of Yeon Gaesomun (which comes out as the western great according to the records) was great. King Yeongryutae allowed Jin Daedeok, a spy dispatched from the party, to travel to the mountain stream of Goguryeo when he asked for permission to travel around the mountain stream of Goguryeo, which was tantamount to causing Jin Daedeok. In addition, at the request of the party, the landscape, a memorial tower for transmission, which was built after winning the war against the Sui Dynasty, was demolished. It was the act of trampling the pride of Goguryeo people that destroyed the landscape. King Yeongryutae lost trust in the people due to the police incident, and King Yeongryutae, who was afraid of criticism from the hard-line faction, appointed Yeon Gaesomun, the leader of the hard-line faction, as the head of the construction of Cheonrijangseong Fortress, but King Onryutae and King Yeonggeon. Yeon Gaesomun, who took power, turned the policy from the Daedanghwa Chinchaek to the Daedang Ganggyeongchaek, and Goguryeo and the party were engulfed in an atmosphere of war. In July 644, Taejong Lee Se-min, who abolished his father and killed his older brother and younger brother to ascend to the throne, carried out an expedition to Goguryeo despite opposition from many officials. In the name of the war, Lee Se-min said, "How can we tolerate Goguryeo Gaemun because he is killing the king and abusing the people?"Using Iranian Confucian logic as the justification, he revealed the cause of the invasion he caused. In 645, Danggun, led by King Taejong, invaded the Liaodong region of Goguryeo one after another. Several castles, including Yodongseong Fortress, Gaemoseong Fortress, and Baekamseong Fortress, have already been captured by Danggun, and Danggun has gathered in Ansiseong Fortress, a key point of Goguryeo and a mountainous area of iron. In order to save Ansi-seong, Yeon Gaesomun dispatched 150,000 troops led by Boulevard Go Jeong-ui, Northern Yoksal Go Yeon-su, and Southern Yoksal Go Hye-jin to Ansi-seong. Ko Yeon-soo and Ko Hye-jin attacked the party forces without listening to Jeong Eui-ui, fell into a trap and lost 3,6800 Goguryeo soldiers, and they became prisoners of the party. Fortunately, many Goguryeo troops, led by Go Jeong-ui, were almost wiped out by the Wadang. In general, it is understood that Goguryeo troops were defeated in the rest of the region except Ansi Province due to the invasion of the party, which is different from the fact. Of course, Goguryeo faced a crisis of falling major castles such as Liaodongseong Fortress, but Goguryeo was still dominant. In the victory of Geonanseong Fortress, the party was tired from guerrilla operations by Goguryeo troops everywhere. According to the eight-year history of the Three Kingdoms, he said, "The army combined with Goguryeo and Malgal reached 40 ri in the Battle of Jupilsan Mountain, and Lee Se-min was afraid that the army could hardly shake off and spy Lee Se-min was greatly surrounded." Although he said he escaped by himself, the danger is the same as mine, but he did not mention it in Shin and Gudangseo and Samagwang's Autonomous Tonggam, so it is recorded that this is to hide something shameful for his country. It can be seen that the Tang army was greatly damaged by the Goguryeo army in the Battle of Jupilsan Mountain. Panicked Taejong tried to attack Ansi Castle to overcome this situation, but let alone fall the castle due to persistent resistance from Ansi Seongju Yang Man-chun, he lost one eye due to Yang Man-chun's attack. Soon, winter came, and the Tang army, tired of Goguryeo's guerrilla war, began to retreat. However, it was not a Goguryeo army that would send the Tang soldiers safely. King Taejong, whose retreat to the Tang Dynasty was blocked by a group of Goguryeo forces that blocked the retreat, took the retreat as a fortress with swampy areas. The retreat to the Yotaek region, where mudflakes spread out everywhere, was too harsh for the Tang army. It was a hard march for Taejong himself to put logs on his horse's saddle and carry them himself. Nevertheless, the pursuit of Goguryeo troops was not delayed. Meanwhile, Goguryeo troops, led by Yeon Gaesomun, crossed the Great Wall and approached Sanhaegwan. The Joseon Commercial History records the situation at this time as follows.

"Yeon Gaesomun left the fluctuating fight to two people, Yang Man-chun and Jeong Sang-guk, and went out to Jeokbongjin to 30,000 Jeongbyeong, and went south again to announce Sanggok, the prince of the party, and stayed in Eoyang." King Taejong soon tried to return the military after learning that a rebellion had occurred in Imyugwan. Ogolseongju Estimation Bureau and Ansijeongju Yang Man-chun guessed that Yeongaemun Gate had already reached its destination and that King Taejong would escape in the future, so the estimated bureau rushed to the narrow valley southeast of Ansiseong Fortress and rushed to attack the party's military. Dang's soldiers trampled on each other and ran away." (중략) "It was not seen in the records that Yeongaesomun Gate broke through, but today, 7 Ridge's Hwangnyangdae, including Beijing Joyangmun Gate, was named Hwangnyangdae, which was built by King Taejong. As it is said to be one place, it is a relic of Yeon Gaesomun chasing Taejong to Beijing, and there is a place name for the two characters of Goryeo in Shandong and Jikye, and legend says that this is the highland occupied by Yeon Gaesomun, and the lowest one is Goryeojin and Haganhyeon in Heo 60ri, Bukbuk-ri." According to Handango, which has yet to be recognized as an official librarian in academia, it has been defeated since Tang soldiers invaded Goguryeo, and Go Yeon-su, who was obsessed with King Taejong of the Tang Dynasty recorded in Chinese librarians and Samguksagi, rather cheered Ansiseong from the east. What's surprising is that Goguryeo troops chased King Taejong, who was tired of chasing and his life was at stake, and Lee Se-min asked Yeon Gaesomun to surrender, and Yeon Gaesomun entered the party's capital Janganseong Fortress. Although Handang meat is currently causing pros and cons from the public, academia will ignore the dubious fact of King Taejong's invasion of Goguryeo (the loss of troops by King Taejong of Tang Dynasty, the party won all battles except for the Battle of Anshiseong). The fact that Suyeo Daejeon and Dangyeo Daejeon returned to Goguryeo's victory is of great significance not only for Goguryeo and Tang Dynasty, but also for the situation in East Asia at that time. With the defeat of the party, the party's plan to directly territorialize the Korean Peninsula was committed, which means that the plan to unite East Asia into a single culture was thwarted. The party tried to directly dominate the area by integrating the fallen Goguryeo Castle into the administrative district of the party, and also tried to carry out their view of the world by reorganizing all countries in East Asia into vertical tribute relations. However, the party's intention was frustrated by its defeat to Goguryeo. Tang Tae-jong, who tried to crush the world of another country to carry out their own world, was eventually completely defeated by another Chinese Goguryeo with another worldview. Rather, he died due to the aftereffects of the Goguryeo War. The victory of Suyeo Daejeon and Dangyeo Daejeon further strengthened Goguryeo's view of the world. The victory of Suyeo Daejeon and Dangyeo Daejeon proved with their skills that Goguryeo was the loser of the East with its own worldview as before. The victory of Suyeo Daejeon and Dangyeo Daejeon is not just Goguryeo's, but the victory of the entire Korean people. According to ☞ Handango, it is recorded that King Yeongryutae killed King Yeongryutae instead of Yeon Gaesomun killing King Yeongryutae. ☞ In fact, the justification for Taejong's invasion of Goguryeo is only an absurd theory. Tang Tae-jong is one of the most sinners in the world who killed his brother and younger brother to ascend to the throne, forcibly deposed his father, and insulted his younger brother's wife. How can he put forward Confucian logic to Yeon Gaesomun, who killed the king for his country? In order for the ☞ Tang Dynasty to defeat the 150,000 troops of Go Yeonsu, it is necessary to mobilize more soldiers than this, but only 30,000 troops were mobilized by the party. Also, on June 23rd, when Ko Yeon-soo surrendered, what did the Wanggunak unit, who died while taking the lead against Goguryeo forces, say? If Ko Yeon-soo's 150,000 troops surrendered, Wanggunak's troops do not have to fight Goguryeo's This suggests that the actual main force of the 150,000 troops of Ansi Province's support forces is the army led by Go Yeon-soo, not the unit led by Ko Yeon-soo. In other words, it can be said that the defeat of Wanggunak's army and the rescue of 30,000 Goguryeo troops led by Ko Yeon-soo were Goguryeo troops led by Jeong Jeong-ui.
