===================== Egypt's Suez Canal ===================== The first canal was planned in 2100 BC, where Neko began connecting with the Mediterranean Sea, causing numerous casualties, and then Darius I succeeded in connecting it to the Nile River Bubastis via the Red Sea and Great Bitter Lakes around 500 BC. This waterway became an important transportation route for Arab merchants in the 7th century to transport Egyptian agricultural products, and was used for more than a hundred years before the transport of grain using the waterway was stopped due to the Muslim infighting. In 1798, Napoleon began the construction of the Red Sea and the Mediterranean Sea, but due to a miscalculation by the chief engineer, the company was reopened in 1859 by Ferdinand, consul of Cairo's French Republic, and a total length of 161 km was opened in November 1869. In July 1956, the Suez Canal Company was nationalized by President Abdel Nasser, who took power through the 1952 military revolution, and the conflict continued, with Britain and France, which lost its vested interests, mobilizing troops to take advantage of it. The canal was then closed due to the Six-Day War in 1967, and with President Sadat's recapture of the Sinai Peninsula in 1973, it was reopened in 1975, eight years after the Egyptian government's closure. An average of 100 ships use it a day, and 14% of the world's traffic passes through the canal, and it takes about 15 hours to pass. The canal is 200 meters wide and the average depth is 20 meters, and as traffic increases, dredging continues to expand steadily, and the canal is now 173 kilometers long. The connection point across the canal to the Sinai Peninsula is four ferry stations and one undersea tunnel, which has a total length of 4 kilometers, including an access road. The canal's harbor is Suez on the Red Sea and Portside on the Mediterranean Sea. ============================= Panama Canal of Panama =========================== During the colonial period of Espanya, the Isthmus of Panama was called the "Kingdom Road" as a route for transporting silver produced by Peru's father's decree to his home country. The Spanish planned to build a canal on the Isthmus from the 16th century, but the gold rush occurred in California in the mid-19th century, raising the need for easy access from the east coast of the United States to the west coast. In response, a U.S. private company began construction of the Trans-Panamanian Railway in 1850 and completed it in 55. When the transcontinental railroad of the United States was not completed, it played an important role as a transportation route between the Atlantic and Pacific Oceans. It was a French private company that first undertook the construction of the canal in 1881 under the direction of F.M. Lesseps, who acquired the right to build the canal from the Colombian government. However, the company went bankrupt in 1989 and the canal construction was halted due to unimaginable difficulties, running out of funds, and threats of malaria and yellow fever. After a French private company failed to build a canal, it was completed by the U.S. government in the early 20th century. At that time, the United States began to advance into Asia and the Pacific region by acquiring the Philippines and Guam in 1998 due to the war with Espanya and merging Hawaii. To make this entry easier, the need for a route from the eastern coast of the United States to cross the Central American Strait to the Pacific Ocean has increased. The 67-day voyage of the Oregon warship from San Francisco to Florida via Cape Horn at the southern tip of the Americas during the war against Spain inspired American politicians and the public to realize the need for canal construction. After the war, the U.S. government began negotiations to revise the Clayton-Bulwer Treaty, which banned the U.S. and British governments from exclusively building canals in Central America. In 1901, the Second Hay-Ponsport Treaty recognized the right of the United States to build a canal and fortify the canal area on its own. At that time, Nicaragua and Panama were expected to be candidates for canal construction in the Central American Strait. The United States decided to take the Panama route, negotiated with the Colombian government, and in January 1903, signed a treaty that recognized the U.S. government's construction and control of the canal in the Isthmus of Panama. However, the threat posed by the U.S. government of T. Roosevelt over the ratification led to a backlash from the Colombian parliament, which eventually refused to ratify the treaty. Meanwhile, the people of Panama, which had been increasingly separated from Colombia, were disappointed by the Colombian parliament's refusal to ratify the treaty and campaigned for independence. On November 3 of that year, they achieved independence from Colombia in the hope of support from the U.S. government. The independence was successful with the help of a U.S. warship, and the U.S. government approved the Republic of Panama on November 6. The United States soon signed a treaty on the canal with P. Vinovarya, the French ambassador to Panama. The treaty was far more favorable to the United States than it had previously signed with Colombia, and the U.S. government decided to pay the Panama government $10 million immediately and $250,000 annually nine years later to "own" the 16-kilometer-wide Panama Canal. Later, disputes continued between the two countries over which side of the treaty was the sovereignty of the canal zone, but it was in favor of the United States. When the canal was opened due to construction between 1904 and 14, it became easier for the United States to enter the Asia, Pacific, and South American Pacific regions. The Panama Canal and the Caribbean region at its mouth have increased strategic importance to the United States. Meanwhile, Panama was semi-colonial and the huge toll from the canal was taken by the United States, so it was stagnant without utilizing the country's biggest resource of transportation. In this way, Panama's economic disadvantages and discrimination against Panamanians in the canal area increased, triggering a conflict over the flag-raising of Panama in the canal area in 1964. In this case, the U.S. government began negotiations for a new canal treaty. But Panama's pressure to return the canal zone to sovereignty grew even higher under the leadership of nationalist General O. Torrijos, a coup d'état in October 1968. The canal has a huge U.S. military base and the Southern Command, which governs U.S. operations in Latin America, which is important to the U.S. military, while on the Panamanian side is at risk of becoming involved in war. Here, as several Latin American countries supported Panama's demands, the United States made concessions, signed a new canal treaty with the Panama government in September 77 and ratified it in April of the following year. The new canal treaty stipulated that the ownership and operation of the canal would be transferred to Panama at the end of 1999, a significant increase in annual payments to Panama, and Panamanians would be involved in the operation of the canal. However, due to the disadvantage that the current canal is old and it takes time for ships to pass, and ships of more than 65,000 tons cannot pass due to its narrow width, the construction of the second Panama Canal is under consideration, with three countries launching the Panama Canal Alternative Investigation Preparation Committee in 1982. For the next 85 years, U.S. control of Panama was transferred to Panama on December 31, 1999.

The Statue of Liberty, a great gift from France to the United States in the late 19th century
Some people seem to think that the "Goddess of Liberty" is rumored to be black, and that it means a slave revolution because there is a chain at the foot of the statue that symbolizes slavery. Of course, the broken chain, which means freed from slavery, means freed from all kinds of slavery, not especially for blacks. Black people aren't the only ones sold as slaves in history. If, as the rumor goes, the Statue of Liberty had modeled a black woman, would the United States have received it as a gift? I don't think it's possible right now. Let's find out about the goddess Sang-ae, who has many half-brothers all over the world! From the Egyptian statue to the Statue of Liberty... Impressed by the huge monuments in Egypt, Bartoldi wanted to create a work worthy of the giant pharaohs, and dreamed of being built at the entrance to the Suez Canal Canal de Suez, creating a female figure who acts as a "lighthouse" rather than a "lighthouse." Egyptian woman, not black! The plan, which was not completed due to capital problems, changed the much advanced hairstyle of the statue, removed the veil from its face, and added a law code to its broken chain and left hand, sending the Egyptian lighthouse, the Statue of Liberty, in European form, to the United States. In 1867-1868, plans to build an Egyptian woman-like lighthouse at the mouth of the canal were canceled, but when the French government heard that something would have to be presented to commemorate the 100th anniversary of American independence, it left for the United States in 1870. Bartoldi, whose work was based on the Bedloe he saw on arrival at New York Harbor, met important people during his stay to explain and persuade them of his ideas and began producing the Statue of Liberty with financial support in 1875. Based on the construction process and technical originals, it began to be made in 1875 in the studios of Mont du Monduit, Gaze Gaget, and Gauthier, located at the 17 Chazelles in Paris. The best architect of the time, "Violet Dook Eugene Viollet-Le-Duc" (1814-1879), who left numerous works during the reign of Napoleon III, as well as the restoration of the Notre Dame Cathedral, will begin work in charge of designing the structure of the statue. When the work was done in the early days of the hip sticking out, it faced structural problems, and it was transformed into a goddess with a more stubborn image than the Egyptian woman who put the protruding hip in and stood upright. The 1.25-meter-tall prototype submitted to the committee was enlarged to 2.11 meters, and then made again to 8.5 meters high, measuring the model accurately and quadrupling it, is the current statue of the goddess. The copper plates, which were up to 1.4 meters long, were screwed and then assembled in the U.S., stacked exactly 25 centimeters over each slanted plate and fixed with a rivet of 5 millimeters thick, and the seam was barely noticeable. It was good that the wealthy Pierre Eugene Secretan donated 300 2.37 millimeter copper plates to surround the exterior of the statue and received the Legion d'honneur, the highest honor medal from the government, but it collapsed in 1889 when the Eiffel Tower was completed. Also, in 1876, a temporary assembly was under way, but it was still incomplete, so only arms with torches could be sent to celebrate the 100th anniversary of American independence, and the atmosphere was chilly. The construction of Gustave Eiffel's role was delayed, and furthermore, the architect Violle-le-Douck, who designed the core structure, died in 1879 without completing the interior structure, and civil engineer Eiffel Gustave Eiffel (1832-1923), who was famous for building a railway bridge for trains, was involved. Ten years later, the Eiffel Tower first reinforces the fragile structure, and then puts copper plates on top of a gridded frame of 5 x 0.8 centimeters of iron bars, which face problems of contraction, expansion, and insulation due to climate change. The problem of contraction and expansion was solved by the flexible structure and wrinkles of clothes, and the insulation problem for electricity generated when copper plate and iron lattice were connected by excellent was solved by inserting a copper plate with waterproof paint between the copper plate and iron lattice. You didn't know the U.S. would take it? It would be understandable to imagine the statue sticking out of the roof until it was dismantled to send it to the United States in January 1884. The completion ceremony was held, numbered each part, and completely dismantled, a total of 214 boxes were loaded into 70 trains, sent to Luang Rouen, one of France's three largest port cities, on a ship called Jezhe Isere, and departed for the United States on May 21. The statue, which arrived in the U.S. in June but completed with a four-month assembly, was said to have been standing in the courtyard of a warehouse called Fort Wood because the pedestal was not yet completed. The Statue of Liberty, which stands on the Seine River, was donated to France by the American Society Community America to commemorate the 100th anniversary of the French Revolution, and was made by reducing the size of New York's big sister (?) to a quarter. On November 15, 1889, the centenary of the French Revolution, it was built on the current location of the Swan Island l'ileaux Cygnes, facing the Eiffel Tower in the Palais de l'Elysee, where the president was in office, and changed its current position to face her sister in 1967. The Statue of Liberty, located near the University of Sorbonne in the Luxembourg Garden Jardins du Luxembourg, where the Senate is located, was donated to Paris by the creator Bartoldi Frederick Auguste Bartholdi for the 1900 World Exposition. The bronze statue, cast with a 2.743-meter-high bronze at a factory called Thiebaut Freres, stands in a pigeon poo with its sisters turning their backs. Following the death of Princess Diana in an underground tunnel at Place de l'Alma, the International Heralt Donation in 1987 is celebrating the 100th anniversary of the International Tribune, which has been used around the world to commemorate the deceased with postcards and flowers. It was chosen as a place of mourning for death.
Reasons why the Song Dynasty's great poet So Dong-pa opposed trade with Goryeo
During the reign of King Munjong of Goryeo, diplomacy and trade with Song were active. In the 34 years from 1047 to 1081, during the reign of King Munjong, Song's official trade ship entered Goryeo 39 times. Goryeo imported more than 100 kinds of goods from Song, including books, clothing, medicinal materials, and musical instruments. Song also imported paper, brushes, lacquerware, pottery, and silk from Goryeo. It is said that a large-scale trading company went back and forth, with the number of merchants reaching 200 once the trading ship entered. In addition, trade was so constant that guesthouses for envoys and merchants were installed in both countries. However, opposition to this active exchange occurred during Song's mediation. Song's representative poet and well-known to us (the pen name is Dongpa-ro, then Byeongbu Sangseo) was a representative anti-communist. The biggest reason he opposed trade with Goryeo was, "We have no profit at all, but Goryeo is taking great profits." In addition, the Sodong faction was lactatively opposed to trade with Goryeo for the following reasons. First, it causes inconvenience to entertain envoys and merchants, and second, it is too expensive to send and receive goods. Third, the goods sent from Song are introduced into the enemy country of Kitan through the hands of the Goryeo people. Fourth, wherever Goryeo envoys and merchants go, Song's mountain stream map is prepared, so state secrets are leaked. Fifth - Koryo is an ally of Kitan. However, these objections were not encouraged. This is because Song, who is confronting Kitan, could not ignore Goryeo, a powerhouse in the northeast. Through equidistant diplomacy with Song and Geoga, Goryeo was able to occupy an advantageous position not only in defense but also in trade.
Confused by Comparison of Buildings
<Territory of Korea and Japan and EEZ> <The Old Holiness of the House> --- After the article <5621 Cultural Heritage~> Do you think that the harsh words and actions such as Hikaru Sun, Red Ki Ho Sun, and Kkukkuh Ha Sun/hyn 217 Sun are somewhat confusing? Not only have they never shabby or disparaged their own culture, but they have not unfairly criticized other cultures...Based on the existing relics, the intention was to recall that Korea's history was a history of division rather than integration, and that the results were completely melted into cultural heritage. I think descriptive errors such as the misunderstanding of the sun and the inappropriate praise of the sun were also factors that contributed to the turbulence. 1. I would like to recommend one or two of the cultural heritages of Korea, Mongolia, and Turkey that represent the country, or compare and discuss the world cultural heritage of the national level. (I would like to cite Turtle Ship as a representative cultural heritage under the assumption that the main seat is existing) There are still many suns that recommend Seokguram Hermitage in Bulguksa Temple as an existing cultural heritage. I don't watch it, but... 2. I don't think this area, where the old capital of Goguryeo and the Hongang River (Biryu-su) was located, including Hwanin and the family, is contrary to reasonable arguments such as Dasan's theory of agitation.Was it historically so hard to protect this place? Reflecting on the history of division since the beginning of the reign of Gojoseon, the vision of the Baikal Alliance, if not the land, is like Russia, Kazakhstan, Turkey, Baikal South, and Russia, but it seems impossible to stand against the Pax American or Chinese hegemony. Rather, isn't it ideal than a creaky Northeast Asian community? There's no such thing as easy.Add a Baikal National Union Map to one of the most talented suns. Just-->5621. A marvelous relic that Korea doesn't have? Let's take a quick look at the beautiful, great, and mysterious cultural heritage left by mankind! Not to mention superfluous Greece, Italy, Rome, Germany, France, Britain, Austria, Spain, the pyramids of Egypt, Iran, Babylonian ruins of Iraq, India, Cambodia, the Great Wall of China, and Japan's Himeiji are amazing, and the pyramids of Machu Picchu Sun. Potala Palace in Tibet... These are the cultural heritage of mankind. These countries and peoples are not one or two... Korea? Bulguksa Temple, Gyeongju Gyeongbokgung Palace, Suwon Hwaseong Fortress, Jangsu Royal Tombs, Goguryeo Castle... The Dolmen of Balhae Palace Site, Jikji of Hangeul, Daejanggyeong, Turtle Ship... It's cute and creative, but it's not too small, not surprising, or mysterious! What else? Well, if the eastern pyramid in the west coast of China has nothing to do with Gojoseon... What could there be? What is the world heritage that you want to show off that represents Korea? Personally, I think the turtle ship is great...You don't have any real ones left, do you?…ㅠ.ㅠ I would like to criticize the history of lack of initiative and division, not cultural disparagement. Overcoming division and dreaming of reunification...You were so hopeful! ->5645 Until a realistic alternative... What if we don't have any historical significance? First of all, it could be plagiarism of the Statue of Liberty. Isn't the harmony of the outlook, the harmony with the surroundings, the religious symbolism of the country, the most wonderful thing? I think it's better than the oddly large Buddha statue that's common in Korea. It seems that Namsan Tower has more commercial quality and national competitiveness. Isn't there any Korean image that anyone on earth would like, representative relics, or Korean scenery that can be used as a wallpaper? Oh, there's "Winter Sonata" Except for the center of character (Korea is the best...) If it's not exclusive to Japan, Himeiji Castle would be cool and if it emphasizes archaeological significance...There's a lot of great ancient ruins in the world, right? America has very little history, but...It was worth boasting about the scenery of the skyscraper, Mother Nature, and the Grand Canyon. The image of Rio de Janeiro, which is one of the world's top three U.S. ports, is used as the desktop of my current computer. There's no other cool image that you'd like even if you weren't Korean. Europeans know how to make buildings big, pretty, solid, and sometimes detailed. Neuschwanstein Castle in Germany? I highly recommend doing it. It sounds like it's burnt out and gone. It's like a piece of course.
If Rhee Syng-man, Park Chung-hee, Chun Doo-hwan, and Roh Tae-woo were in the development dictatorship, there was Yang Kim in the democratization process
Kim Young-sam, who started his political career almost at the same time as Korea's politics in the 1950s and took control of the opposition party in the run-up to Yushin's declaration in 1970, Kim Dae Jung...Yang Kim! After that, he fought with Park and temporarily formed three Kims with Kim Jong-pil. The Reagan administration saved Kim Jong-pil from exile, Kim Jong-pil from the U.S. for corruption, but Yang returned to the presidential election after the June 1987 uprising. If Kim Young-sam and Kim Dae Jung unified their candidates, they would have beaten Roh Tae-woo, leaving a fatal moral error. In January 1990, Roh Tae-woo, Kim Young-sam, and Kim Jong-pil joined the three parties. Everyone was shocked to hear that Kim Young-sam was involved, but in 1992, he won the seat of the ruling party and took office the following year. The fatal mistake of the IMF economic panic in later years. Kim Dae Jung temporarily retired from politics after a defeat in 1992, but returned to power in the run-up to the 1997 presidential election, thanks to the IMF economic panic. It is meaningful that Kim Young-sam was the first democratic force to take power, but the weakness of taking power while being scouted by the ruling party due to the integration of the three parties. Kim Dae Jung was the first to achieve a regime change, but Kim Jong-pil and Yang Kim both succeeded in taking power, but it was inevitable to join hands with the civil affairs community or Kim Jong-pil or some of the military dictatorships. I'm going to throw it out later. Kim Dae JungIn the early days of his administration, he was busy trying to heal the economic depression of the IMF, and had to divide his power with his predecessor. Of course, a summit meeting with North Korean leader Kim Jong-il in the 21st century? What is a top here? Tosa-Gupin...........take advantage of it and throw it away when it's not needed...........they've run for president several times since the 70s and hammered a five-year democratic president in the 90s.................did they want to do that after decades of fighting against military dictatorship? A democratic president has limited power. Roh Moo Hyun is their son.......................after the June 1987 uprising was successful, Kim Young-sam scouted Roh Moo Hyun, a famous human rights lawyer, and emerged as a star at the 1988 hearing. In 1990, the three parties were united and separated from Youngsam to remain as an opposition party, and in 1995, Noh Sa-mo was founded... After that, he went under Kim Dae Jung and won the presidential nomination in 2002 and took office in 2003. Jong-pil has always been the second and third-in-command, but he was virtually defeated by the public in the new century, lost the parliamentary election last year, and retired from politics. The end of Kim Jong-sik's reign has been claimed by those who have been absent from meetings since the 1990s after the failure to unify the candidates, but it is now over after 10 years of presidential election and two or three people. Are you saying that this is reality... ...I personally think that the development dictatorship forces and these Yang Kim democratization forces... ...are great people. What is the current power of the muhyun or nepotism? I don't know... ================================================================ An indispensable rival in Korean political history. President Kim Young-sam and President Kim Dae Jung. These two people were commonly called Yang Kim, and later they were also called Sam Kim, including Kim Jong-pil. After the Roh Tae-woo military regime, he was the president of the Civilian Government and the People's Government. These are the characters who left a great mark in the history of the Korean constitution. Geosan Kim Young-sam was born in Geoje, Gyeongsangnam-do, graduated from Seoul National University's Department of Philosophy, became the secretary of Prime Minister Jang Taek-sang, and was elected to the National Assembly in 1954 as the youngest ever (26 years old). Since then, he has served as a spokesman for the opposition, five floor leaders, and three floor leadership posts. He is the youngest member of the National Assembly in Korea and the most elected (9th) in history. He failed in the 1987 presidential election, but he merged with the Democratic and New Republicans in 1990 and became the supreme council member of the Democratic Liberal Party. The announcement of a series of reform policies in power did not lead to full public support, but in 1995 he accused former presidents Chun Doo-hwan and Roh Tae-woo under the pretext of "straightening history" but was controversial, and in 1997 he received the I.M.F. bailout. At the end of the reign, the people will be blamed a lot. Huguang Kim Dae Jung was born in Sinan, Jeollanam-do, graduated from Sanggo and worked as a businessman, entered politics in 1960 and faced President Park Chung-hee in the 1971 presidential election, but unfortunately lost. He was imprisoned for the 1973 Kim Dae Jung kidnapping, 1976-78, and when the Gwangju Uprising broke out in 1980, he was sentenced to death for conspiracy against insurrection by the new military. He retired from politics after losing consecutive presidential elections in 1987 and 1992, but returned in 1995 and was elected the 15th president of the Republic of Korea in 1997. The first inter-Korean summit, known as the "Sunshine Policy," improved the economic situation by escaping the IMF bailout, but it is also fatal to morality as immoral political reform attempts and corruption by close aides and family members appear one. Kim Young Sam and Kim Dae Jung... They are the president and politicians of the Republic of Korea, fighters who took the lead in democratization, and great figures who contributed to the political development of the Republic of Korea. There were also many evils such as politically promoting local sentiment and realizing boss politics by one person.
To be honest, Rhee Syng-man and Chun Doo-hwan are shameful and shameful human trash in history.
a township in the Joseon Dynasty that had no salary
When it comes to Hyang-ri during the Joseon Dynasty, I think of Ibang, which is said to be "Yeah~ Sato" and makes a fuss to local leaders. The people saw Hyang-ri as the main culprit of the exploitation of taxes, and the leader treated him only as an unbelievable junior official who always tried to deceive him. Local officials could not perform their duties without Hyang-ri's assistant when they took office, but for them, Hyang-ri was only an object that "should not be treated as a person's duty, should be supervised and controlled by law." It was Joseon's court that structured the bad image of Hyang-ri. The court entrusted Hyang-ri with the work without paying him an inch of land or a penny. It was given as a kind of honorary position. However, Hyang-ri had to take charge of all the practical affairs of the government office, from tax collection to the execution of servants. Without them, work was paralyzed. And the expenses for carrying out the heavy work went in prohibitively. Yangban was a landowner with land in the provinces, but Hyang-ri did not have much land. They had no choice but to commit public embezzlement in order to raise living expenses and job performance costs. To do so, the people had to squeeze in to collect more taxes than they had allocated. In other words, the Joseon government forced Hyang-ri to cheat structurally, but not everyone could win the favor of Hyang-ri Lee Im-jari, who performs the duties of the government office in Hyang-ri, was able to take over after more than 5:1 competition. Yi Bang, the epitome of Hyang-ri, was the highest position and yolk seat for Hyang-ri to climb. It is said that he had to wait for 30 years to become a foreign room. In the late Joseon Dynasty, when corruption was prevalent, Lee Im also became a place where money was needed. It goes without saying that he carried out intensive exploitation to get his money's worth as much.

A Case Study on the Inspection of Spanish and Ming Dynasties Using the Tactics of the Jangchang Unit
If there was a Nagayari in Japan, there was a pike in Europe, and there was a jangchang in the Ming Dynasty. At that time, as gunpowder weapons began to be introduced in most cultures, infantry units armed with long spears along with gunpowder guns pushed swords, irons, and Mays out of the battlefield and emerged as the main force. They were used as defensive defenses to protect our gunmen from cavalry charges, and in some cases, they lowered their spears horizontally and advanced, pressing enemy infantry or forcing our gunmen into positions that were easy to fire. However, even in the situation where Jangchang is becoming the main cold weapon, each soldier uses a sword to break into the enemy's spear corps and disrupt the ranks only has a low proportion, but it has not disappeared. In the case of Espanya Tercios, in order to protect the Pike Corps, they placed a group of soldiers on the side of the spearmen, along with a round shield called Rodelas, and a sword-armed force. In particular, shield soldiers often used tactics to break into the flank or rear of enemy Pike units during combat. At that time, European soldiers, like Japan, had guns, pikes, and barons on their backs, and even if an enemy swordsman broke into the ranks, they would have to throw their spears and pull out their swords to fight, so even if they tried to fight against the enemy's invasion, they would have to collapse. Of course, he didn't miss the moment when he found out that the orderly ranks were collapsing, so he fired fire guns and cavalry and Pike soldiers attacked. Let's take a look at the case of Yuanangjingyo, an infantry tactic created by Cheok Gye-gwang, a general of the Ming Dynasty who was suffering from Japanese pirates at the time. Wonangjin is the card of victory created by Ming, who had been suffering from Japanese aggression since before the Japanese Invasion of Korea in 1592, to fight against the Japanese sword and the Chochong. It's a method that the famous General Cheok Kye-kwang made. In a one-on-one individual fight, he invented a tactic that responds in groups because he can't be beaten by Japanese pirates. The Yuan Dynasty basically consists of 12 soldiers, of which the main combatants are 10. One is a captain and one is a reserve. These 10 soldiers are arranged in two rows and each soldier uses a weapon that suits him, the first two armed with a dorsal plaque, the next two armed with a dorsal gland, the next four armed with a javelin, the last two armed with a partisan. They move closely like a rope and a rope to defeat the enemy. The reason why the name of Jin was called Yuanangjin is because Yuanangjin emphasizes harmony and harmony with each other, just like a mandarin duck bird that dies after one dies. In fact, these mandarin ducks were very powerful to the Japanese army, armed with a long spear and a Japanese sword. It was also thanks to Yuanangjin that Chukga was able to win consecutive victories over Japanese pirates. The Byeonghakji Namyeon, a Byeongseo compiled in the late Joseon Dynasty, states the power of Wonangjin. After Ming troops entered Pyongyang, they fired artillery first, followed by slash-and-burn fire, and smoke. The Japanese invaders were finally discouraged. When the enemy rushed first, they concentrated the Nangseon unit and waited, and if the enemy did not move, the back losers advanced with their back plates, and the Japanese lost and ran away. It's invincible." You can't see Tersio and Yuanjin the same way, but they have something in common in that they understand the weaknesses of a unit made up of only soldiers, and they operate a single-armed unit, especially a sword with a shield. During the Warring States Period and the Japanese Invasion of Korea in 1592, there was a batdo-ashigaru unit armed with a large sword, but they were used to fight close to the enemy in chaotic situations where they could not use guns or arrows at the end of the battle, rather than to break into the enemy's camp.
