In order to reverse the situation of World War II, Japan developed an atomic bomb in Heungnam (now Hamheung, Hamgyeongnam-do), North Korea, and even completed an explosion test in the sea, drawing attention. MBC's "Now I Can Say It" will make the claim in the "Unfinished Secret Project - Japan's Atomic Bomb Development" (planned by Kim Hwan-kyun, directed by Park Gun-sik), which will air on the 12th. The reason why the production team raised Japan's "Development and Experiment of North Korea's Heungnam Atomic Bomb" was because a confidential information report by the Allied Command (GHQ) was discovered in 1947 by Wilcox (author of "Secret of War" who was a former U.S. journalist. The report, written by U.S. lieutenant colonel Cecil at the time and called the Cecil Report, records that Japan had developed an atomic bomb in Heungnam, North Korea during World War II. The Cecil Report is based on an article published in the U.S. newspaper "Atlanta" on October 3, 1946. "This information was obtained while David Snell, an agent of the U.S. Criminal Investigation Agency, was interrogating Wakabayashi, a Japanese officer, shortly after the end of the war," the Atlanta Shimbun reported at the time. The Wakabayashi newspaper, later named the Snell Report, said, "In the early morning of August 12, 1945, there was a huge explosion off the coast of Heungnam, accompanied by flash and mushroom clouds." In the end, the U.S. government conducted a full reinvestigation of Heungnam immediately after these reports, and concluded that Japan developed an atomic bomb in Heungnam the following year and completed a secret experiment. In addition to atomic bombs in Heungnam, the Allied Command's intelligence report also states that Japan has been carrying out production of German-made long-range missiles V1 and V2 under the code name "NZ" that terrorized the entire UK in 1944. It was later discovered that the code name NZ was the same name as Hitler's atomic bomb development plan. The production team also added testimony from those who witnessed the production plant in Heungnam at the time. Moon Bong-soo, a student at Heungnam Technical School at the time, said, "Unlike ordinary factories, it was built of concrete on all sides like nuclear power plants," adding, "I asked other people and heard that they were making high-performance bombs." Choi Ki-sun, a factory researcher at the time, also won the postwar Nobel Prize, and Hideki Yugawa, a key member of Japan's atomic bomb development, testified that he frequently appeared in Heungnam with a group of people. In addition, Leon Thompson, an American who was a member of the Atomic Bomb Investigation Team of the Allied Command shortly after the end of the war, said in an interview with the production team, "I could see the atomic bomb designation through the Japanese, and I can't remember the exact name, but I heard that the Japanese military built the largest facility somewhere in North Korea. Why did Japan set up an atomic bomb development plant in Heungnam, North Korea, not in its own country, which is the best place to develop atomic bombs under all conditions such as Heungnam and electricity? The production team is once again looking back at the situation in mainland Japan and the geographical conditions of Heungnam. After the attack on Pearl Harbor, Japan continued to win consecutive wars against the United States, but lost its leadership in the Battle of Midway in May 1942. In a hurry, Japan needed special measures to reverse the war at once, and the military ordered Dr. Yoshio Nishina, the top master of Japanese science, to develop an atomic bomb. In response, Dr. Nishina, led by the University of Tokyo's Chemical Research Institute, carried out a plan to develop an atomic bomb called "Niho Research" in secret, and finally succeeded in separating uranium 235 from uranium raw materials through particle accelerators. Uranium was imported in large quantities into submarines through Germany. However, when the U.S. launched an air strike on mainland Japan in March 1945, the situation was not favorable. The Institute of Chemical Technology, which was the center of atomic bomb development, was also destroyed by indiscriminate air strikes by B-29 bombers. In preparation for this, however, Japan built a separate research center in the village of Ishigawa, four hours away from Tokyo, and continued its research. On the other hand, Japan has turned to the excitement of North Korea. At that time, Heungnam was a large-scale industrial city such as Pohang and Changwon. Heungnam peaked in the 1940s and had a total site of 6 million pyeong with 45,000 employees. Heungnam also developed the Yalu River water system, allowing 3.2 million kilowatts of electricity to be used. This was more than half of the power usage in mainland Japan. Electricity was also a prerequisite for the development of atomic bombs. The U.S. also paid attention to this point, scouting the Heungnam area several times from February 1945 and targeted it as a major attack target, and later, when Heungnam entered the sphere of influence of North Korea and the Soviet Union, it devastated Heungnam during the Korean War. Director Park Kun-sik said, "Japan is the first and biggest victim of nuclear radiation on earth, but as Prime Minister Sato won the Nobel Peace Prize in 1974, we are now a country that can make nuclear weapons in 90 days."

Circumcision is the world's No. 1... history of circumcision
Circumcision has a very long history. Guess it probably started in the Middle East in the Neolithic Age. Now, of course, the oldest surviving reference to circumcision is that Abraham and his family, slaves, and Gasol are all circumcised in the Genesis of the Bible Genesis. It's only assumed that the meaning of circumcision was a kind of burnt offering, perhaps beyond the era of human sacrifice. In other words, it is only assumed that it may mean a religious meaning of "sacrifice" only a part of the body, not a sacrifice in the past that took away lives. The Abrahamic period of Genesis is only about 4,000 years ago. The evidence that circumcision existed before then is that some of the Egyptian mummies that are about 6,000 years old are preserved under circumcision That's not to say that not all Egyptians were doing a circuit at the time. Some people think that the circuit of the Egyptians was a very humiliating ritual of being prisoners of war or slaves.So some people think that this "humiliating ritual" was embraced by the Jewish people who were enslaved in Egypt The Jews continued this ancient religious ritual, the circuit, to the modern day. Of course, historically, there was a lot of persecution of circumcision by Greeks, Romans, Europeans, Muslims, except for Jews, did circumcision, and it's the circumcision of Muslims that now accounts for most of the world's circulation in the world. While Jewish circumcision is a requirement to be Jewish and a religious ceremony held after eight days of age, Islamic circumcision is just a "recommendation" and there is no specific time limit. As a result, there are various aspects of circulation, and depending on the country and tribe, it is implemented from childhood to just before marriage. Interestingly, the circumcision of our country, which has nothing to do with Islam, has a similar pattern. What's interesting is that other than the Middle East, some African tribal countries that are not Muslim, some Native Australians and some South American Indians seem to have been doing the circuit for a long time, regardless of Islam. This suggests that the source of circumcision could go into the Paleolithic. Circumcision, which was mainly limited to religious rituals and rituals of passage in Muslim and Jewish cultures, became popular in Britain and the United States by the end of the 19th century. At the end of the 19th century, Britain and the United States had a "Victorian" motivation to reduce self-defense, reduce energy, and reduce the number of sex. All kinds of sex were bad and there was a pervasive notion of a kind of "necessary evil" that was only necessary to have children. As a result, circumcision has begun to be recommended as a way to reduce self-defense and reduce energy. Circumcision has also spread to other English-language cultures such as Australia, New Zealand, Canada, Australia, and New Zealand, but these days, it is almost disappearing from England, Canada, Australia, and New Zealand. The United States is also declining, but more than half of the population is still doing circulation when they are newborns. Circumcision in the U.S. spreads to South Korea and the Philippines. Our country was introduced around 1945. Interestingly, the circulation of the Philippines and Korea was influenced by the United States, but it was not mainly performed when it was a newborn, but "regardless of age." This is similar to the Muslim aspect, which in Korea may have been influenced by the American mini-series "Roots," which was shown in the 70s. In world history, an example of many people receiving circulation regardless of age in a short period of time like our country is probably not easy to find even if we go to the Bible era. - Source: NAVER. - For your information, Korea is the world's No. 1 circuit. Korea 80% Israel 70% US 55% China & Japan 3% Europe less than 1%
What happened in the death of Deng Xiaoping in 1997
As we get to the story of the Chinese split... ...I remember what happened at the time. During the Tiananmen Square incident in 1989, Deung So-pyeong slaughtered about 7,000 people and withdrew instead. Cho Ja-yang, who was considered a likely successor, was put under house arrest. Died a few months ago. Kang Taek-min, who was in the Shanghai market, was appointed as his successor in Beijing... ...and Deng Xiaoping's power has not been lost. Mo Taek-dong, who stepped down after the failure of the Great Leap Forward Movement, has the loyalty of generals. He further encourages capitalism in China in 1992 when he looks back at the Southern Special Economic Zone called "South Sunghwa." In other words, democracy is unacceptable, but capitalism is accepted... ...and half the arguments of Tiananmen students. In fact, from this point on, China is closer to a capitalist country than a communist one. After Deng Xiaoping took power in 1978, capitalism was gradually realized, but in the 1990s, it was much closer to that. But there are still orthodox communists in the Communist Party of China... ...who are older people like Yang Sang-gon, who are from the guerrillas, and some of them even had military power that was called warlords only a few years ago. In addition, there were many rivals of Prime Minister Lee Bung and Gyoseok who faithfully carried out the Tiananmen massacre in response to Deng So-pyeong's verbal dispute. Plus they're mostly orthodox communists... ...who run against Kang Taek-min's capitalist policies. For this reason, Kang Taek-min's regime is at stake in its early days... ...and can be pushed back to the Reds at any time... ...or China can be divided into capitalism and communism... ...and this story is misleading to the international community. In fact, at that time, Guangdong Province in southern China was the most prosperous capitalist paradise in the world as a special economic zone, while the interior was a red, backward country... ...and very heterogeneous. Guangdong Province has been a window for Western culture since the arrival of Portuguese people in the 16th century, so it is very open to foreign culture, with Sun Moon's Kuomintang Second Government established there in 1917. But at the end of the century, it was once again a window of foreign culture. However, there were many factors of good fortune in China, one of which was the long-lasting vegetation of Deng Xiaoping. From the end of 1994 to the death of early 1997, it became a return letter without dying for nearly three years, and I think this was a great dance for Kang Taek-min. Deng Xiaoping respected both the old members of the carrot Communist Party and the conservatives... ...Kang Taek-min's technology officer in capitalism. That's how you use the power of the old man in the back room. However, if he dies suddenly, Kang Taek-min is attacked by old people and conservative communists. In the meantime, it lasted a long time as a return letter... ...so Kang Taek-min was able to clean up these "real red" who were getting in the way. You can put forward the title of Deng So-pyeong's successor. At that time, novels about China's division were pouring in from the United States, Japan, and Korea. Good luck to China. In February 1997, Deng So-pyeong was punished by the Tiananmen massacre, and he died a few months before he entered Hong Kong (July). Hong Kongers were terrified when the return was decided in the 1980s, but in the 1990s, they accepted it with nationalistic feelings. The continent is capitalizing. Cantonality right in front of you is the Mecca. After the return of Hong Kong, Kang Taek-min cleans up the opposition at a major party and political leaders' meeting that year. School seats are down, Lee Bung is down, and cold rice. 1997 will be an important year for China too, but first get Hong Kong back and one absolute monarch disappears. The Chinese emperor, such as the Kuomintang government of the Kuomintang, Mao Zedong, etc., maintained his power even when one person left office with absolute power. Unwavering loyalty of the generals, but Kang Taek-min did not have that absolute power. wiped out the oppositionHowever, he is only the head of a collective dictatorship. As a result, Hugeum handed over power to Hugeumdo last year, and I know that Hugeumdo was also nominated by Deng So-pyeong. Also, China has become a complete capitalist country, but the old communist pain has been eliminated. There are still communists inside under the title of the Communist Party of China, but even Kang Taek-min showed the intention of Park Chung-hee's development dictatorship that China should have democracy... ...but it's too early. These events in China at the end of the century may be one of the most amazing milestones in Chinese history. Of course, China should eventually become a well-off country. At the same time in Taiwan, democratization progressed, and the Chinese nation was developing side by side. After President Lee Deung-hwi in 1988, progressive democratization progressed, and the first presidential election system in 1996. Perhaps this is the first time in Chinese history that ordinary people have chosen the supreme ruler. The Kuomintang finally stepped down in the presidential election in 2000 and the Democratic Progressive Party took power. The change of government. At the end of the century, China, Hong Kong, and Taiwan showed remarkable progress in democratization as the economy developed. That's what Chinese young people are all about. The Chinese people are always poor, they're always suffering from corrupt officials, absolute monarchs, they disappear for thousands of years.
The Last Three Daimyos of Japan in the Joseon Invasion Army
Yasuharu Wakizaka: One of Shizukatake 7 was the West Army from Sekigahara (West Army vs East Army) but betrayed to East Army... (Shizukatake 7 is a trash gun except for Kato-Yomasa and Fukushima-sanori, so don't look good at me.) Yoshitsu Otani (Higayoshi...) from Sekigahara.This is the guy who followed Hideaki and attacked Yoshitsugu. (Hideaki = responsible for 20% of the West)
Hideo Ukida: One of the five most powerful forces in the Toyotomi regime that Hideyoshi loved so much that he treated them like a son.So he was also commander-in-chief during the Japanese Invasion of Korea in 1592. He's not very good at commanding combat.In Sekigahara, they fought against the East's Fukushima, and they fought a neck-and-neck battle with three times as many troops -_- Stupidly... Still, despite the defeat of the West, the traitors Hideaki said they would kill him with their own hands, and the retainers finally stopped him. The family was destroyed by the defeat of Sekigahara and lived in exile for the rest of their lives.
Konishi Yukinaga: I was a long-term man who came in and out of the Ukida family as a child and became acquainted with Hideyoshi, who was close to the Ukida family, and was mainly in charge of administrative affairs and distribution. My father was a merchant, so he was more capable than a battle. He was the vanguard during the Japanese Invasion of Korea in 1592.In Sekigahara, they fought with the West.We fought well, but Hideaki betrayed us and ran away.He had to commit suicide as an armed man, but he was arrested and killed because of his desperate Christianity.The Pope mourned after his death.
Merchants of the Han River and Hanyang, Joseon in the 18th century
With the development of sea roads and ports in the 18th century, goods produced in various regions of the country gathered in Hanyang through the Han River and then dispersed through the Han River again. The Han River flowing from Gangwon-do to the West Sea, especially the river flowing around Hanyang from Gwangnaru to Yanghwajin, was called Gyeonggang, and commercial activities in this Gyeonggang area were the most active. In Gyeonggang River, the so-called Han River, Yongsan River, and Seogang River were the core. The southern part of Namsan Mountain to Noryangjin was called Hangang River, the western part of Noryangjin to Maponaru was called Yongsangang River, and the western part of Maponaru to Yanghwaru was called Seogang. Around the Gyeonggang River, the shipbuilding industry was also developed, and at that time, there were shipyards boasting excellent technology on Bamseom Island. Gyeonggang merchants, who connected the nation's commercial districts through sea transportation and water transportation, had excellent navigation skills along with shipbuilding techniques. As a result, the number of ships going to and from the Gyeonggang area naturally increased, and the number exceeded 2,000 ships, including small ones. In addition, the size of the ship has gradually grown, and there are about 120 large ships that can carry 1,000 rice. As maritime traffic developed like this, more and more goods were bought and sold, and many people gathered. As a result, the Gyeonggang area of Hanyang in the 18th century suddenly became larger than before. Hanyang, centered on the Han River, grew into a commercial city, and as its scope gradually expanded, new places to exchange goods began to be created around Hanyang. Songpajang Market, the route to the Samnam (Chungcheong, Gyeongsang, Jeolla) area and Yeongdong area, Nuwon Branch in Yangju to the northeast area, and Songwoo Branch in Pocheon were new exchange places. Among them, Songpa, which was the hub of transportation where two waterways leading up and downstream of the Han River and land routes to the east and southern regions met, was the most notable distribution hub. The merchants of Songpajang held a playground to attract people, which is "Songpa Sandae Nori." Another distribution hub near Hanyang, the Nuwon branch in Yangju, also held a "Yangju Byeolsandae Nori" to attract customers. The development of commerce has brought great changes to the lives of the people of the Joseon Dynasty, who lived without leaving their land for generations. When I went to the market, I watched strange things and heard various news. In the 18th century, the customs of commerce changed enough to go to both heads of the peninsula and bargain. Hanyang's market was designated and created by the state when the Joseon Dynasty moved from Kaesong to Hanyang, and commercial transactions within Hanyang's capital have been centered on market traders since the early Joseon Dynasty. There were special rights and obligations in the city, but in addition to the obligation to dedicate goods to the country, they had the privilege of not being able to conduct commerce unless they were market merchants in Hanyang. In other words, all goods traded in Hanyang were purchased at once at Sijeon and then distributed again through Sijeon as retail or wholesale. In the case of violating this, it was strictly prohibited because it was called a difficult war. This is the "money war zone" that regulates the city war. Hanyang's Gyeonggang area and Songpajang were also subject to regulation because they were called difficulties. However, the demand of Hanyang people cannot be met by the old times alone. As the volume of agricultural products increased, the number of marketplaces increased to about 1,000, and with the implementation of the Daedong Law, the population of Hanyang increased rapidly as even people without land could sell their products in Hanyang. While Seoul's population and trading volume were not up to par with the increased market price, Nanjeon merchants, or free merchants, made huge amounts of money by creating a new distribution system that bought and sold goods directly over Xijeon merchants. As the power of free merchants grew, King Jeongjo abolished the controversial Geumnanjeon Hall for decades since the reign of King Yeongjo. In the end, rowing also recognized the power of newly grown free merchants.
the evils of Indian Islam
Islam's belligerence and barbarity - India's serious Muslim problem, and every time you open your mouth, you say crusade Islam is a religion of peace, and you'll have to see what they're doing. Islam, which has invaded a country of normal people, destroyed religion, slaughtered it, and left its remnants to do all sorts of harm to India... No matter how good an Indian is at heart, I won't put up with it any more... They're going to take out a rock with a rolled-on stone. I think we need to understand why Islam is a catastrophe. Of course, there's a dogma who's brother to a dogma. I hope you know that the religion of Gaeslam is more than this religion because you're telling the truth well, because you're talking about prohibiting rituals in Korea. I hope this trash religion will be eradicated soon. There is a conflict that cannot be easily resolved even in India, which is under the slogan of "unification in diversity," and in fact lives in such harmony. It is a confrontation between Muslims and most Hindus in India. It may be well known that the cause of the most brutal and harrowing war in history is mostly due to religious conflicts. India also suffered the greatest ordeal from religious problems and is still experiencing them. It was the Mughal Empire that Muslims invaded and occupied northern India in the Middle Ages, and the conflict between Muslims and Hindus continues until this moment when the Mughal Empire stepped down. Upon independence from the British colony, Indian independence hero Mahatma Gandhi was assassinated. The reason was the conflict between Islam and Hinduism. Eventually, India was separated by the separation of Muslims from Pakistan. Subsequently, eastern Bangladesh was followed by independence by Muslims. But the conflict is not over here. Sporadic fighting over the territorial rights of Kashmir has continued in recent years, and terrorism has been carried out throughout India. In 1994, a massive shell explosion in 17 Mumbai locations in one minute killed millions of people, killed President Rajio Gandhi in a bombing, and a recent clash in Ayutthaya, India's Hindu holy city, killing thousands. It is noteworthy that the attack on Muslims against Hindus is almost one-sided. Ayutthaya is a traditional Hindu holy place, where King Baba, the first king of the Mughal Empire founded by Muslims, once stayed here for a while. Muslims have called for the construction of a monument to King Baba in Ayutthaya to commemorate this. The problem is that they want to tear down Hindu temples and build Muslim monuments on them. Naturally, there has been a huge conflict and the embers remain unresolved. Hindus in India do not deny or reject Islam. At least in appearance. Originally, Hinduism itself was a polytechnic image, so there is no exclusivity for other religions. Hindus also believe in Buddha and Jesus. Of course, Allah does not deny it. But the Muslim argument is different. They demand a complete Muslimization throughout India. Currently, the Muslim population in India is only 12% of the total population. In fact, this figure has tremendous implications. Of all the religions currently on Earth, Islam has the strongest propagation power. In history, no country has been ruled by Islam for more than 100 years and has not progressed in Islam. However, even after 500 years of rule by the Muslim Mughal Empire, only 12% of India returned to Islam. That is not to say that Hindus in India actively fought against Islam. When Islam ruled, it was recognized as it was. And after the Muslim retreat, it was returned to Hinduism. It is indeed a frightening potential. Then, how is it possible to attack Hindus, which account for only 12% of Muslims? The answer can be found in the mafia and terrorism. There is also a powerful night president mafia in India. And the power is beyond the imagination of the general public. These Indian mafias, mostly Muslims, are active in large cities such as Mumbai, Delhi, and Chennai, and some even say that it is the Muslim mafia force that moves India. They hold most of Mumbai's commercial districts, especially the fact that 80% of Mumbai's core commercial district, Kolaba, is owned by Pakistanis linked to the mafia. Indian mafias are said to be mobilizing huge funds to mobilize politicians and some police, and are sometimes reported to be deeply involved in political terrorism and arms trafficking. It has been a long time since such a conflict, crouched inside India, which seems only peaceful for a moment, has become India's biggest concern. Attention is focusing on what kind of situation India's traditional Hindus will face in the future, with Muslim mafia forces dreaming of becoming Muslim throughout India and Pakistan's challenge. As expected, no religion, political power, or force will conquer Hinduism rather than occupy India. In a way, Hinduism is a part of life because it has no substance. Perhaps right now, India's radical Muslims are working alone to conquer the unidentified Hindu religion. (See "Is India a Kingdom of God")
Korea's First Public Opinion Poll During the Sejong Period of the Joseon Dynasty
-The nation's first opinion poll conducted in the 12th year of King Sejong's reign was conducted in 1430, the 12th year of King Sejong's reign. The king's order was the will of heaven and an unconventional policy was implemented to ask for the opinions of the people in the Joseon Dynasty, when it was like a law. There is no record of the method of polling during the Sejong period, but it is presumed that the official visited the people and asked for opinions and collected them one by one by one. The poll, conducted during the reign of King Sejong, asked the public for and against the implementation of the "public law," a new tax law that requires people to pay the same tax regardless of land quality, good harvests or poor harvests. The poll was conducted on most farming households, which took as long as five months. It was a large-scale poll involving a total of 172,648 people, including the heads of the government and the heads of each province as well as ordinary people. According to the results compiled by Hojo, 98657 people were in favor and 7,4149 people were in favor, which was about 57% of the people surveyed. And nationwide, Jeolla-do and Gyeongsang-do regions had a lot of approval, while areas where the land was dry and not greasy, such as Hamgyeong-do and Pyeongan-do, had high opposition. The opinions of the government were different from those of the people, so the people were generally opposed. The reason was that it was unfair to pay the same tax regardless of the quality of land or the poor harvest of farming, and that the national treasury would be poor with a tax of 10 heads per grain. What is interesting is that even among officials, pros and cons differed depending on their status. While most officials under three items were in favor like the people, senior officials above Panseo, who had the right to decide on national policy, were opposed. Implementing a new tax law meant new measurements of land. Therefore, high-ranking officials, worried that the hidden land would be revealed through this process, opposed the implementation of the public law. According to the records of July 15, 2012, Sejong said, "If the people are not good, they cannot implement it." Sejong was already well aware that landy maintenance and officials would oppose the new tax law, so he wanted to borrow the voice of the people to enforce it. This poll shows the true face of Sejong, who knew what the people's will was and tried to engage in politics with the help of the people. The reason why Sejong was able to implement the construction method despite the opposition of his subjects was that there were more farmers who could pay taxes. Until the Goryeo Dynasty, field farming exceeded 80% of the entire land, and it was common to farm every one or two years. Then, in the Joseon Dynasty, most of the land was changed to the serial farming method, which farms nonstop every year. In addition, from the end of the Goryeo Dynasty to the early Joseon Dynasty, reclamation projects and wilderness reclamation projects were actively carried out, increasing farmland. In addition, Sejong distributed developed farming and serial farming methods in Gyeongsang, Jeolla, and Chungcheong regions to areas with poor soil quality. To this end, in the 12th year of King Sejong's reign, the first Korean agricultural book, Agriculture Directs, was compiled. Agricultural Directs is a book made by collecting only the wise farming methods of experienced farmers in each village across the country. Through this book, Sejong hoped that agricultural technology across the country would reach the same level by helping the people suffering from barren land and spreading developed farming methods in Jeolla and Gyeongsang provinces across the country. However, when conservative farmers did not believe anything else except what they had experienced and harvested, Sejong planted the first grain of land under the auspices of Gyeongbokgung Palace and cultivated it himself according to the direct theory of farming. As a result, King Sejong was convinced of the effectiveness of farming directions as he harvested almost several times more than the amount reported. What was newly confirmed after publishing the farming logic was that the appropriate time was essential to increase agricultural productivity. Accordingly, Sejong ordered the development of various scientific devices that can measure the time and seasons of Korea, making it a sundial in the 19th year of King Sejong. This watch was an instrument that could tell the season as well as the time. In addition, in Korea's climate, where spring drought is severe, farming was determined by how to use rainfall and irrigation water, so in the 23rd year of King Sejong, a rain gauge that can measure the amount of rain was invented. The production of these astronomical scientific instruments had a great influence on the increase in agricultural productivity, resulting in a four-fold increase in productivity compared to the end of the Goryeo Dynasty. Agriculture was the foundation of all industries during the Joseon Dynasty. Therefore, during the farming season, the king's travel was reduced, and the government office banned lawsuits. Moreover, since most of the country's taxes were dependent on farmers, kings and bureaucrats could not help but pay keen attention to farming. Therefore, it was only natural to ask farmers for their opinions on the new tax law through public opinion polls. It was in 1444, 14 years after the poll, that the public law was finally finalized as an official tax law. However, even after the construction law was finalized, it was not implemented nationwide due to many unexpected objections. Despite opposition from his subjects, Sejong pushed ahead with the construction method nationwide, developing farming methods and devices that could increase agricultural productivity. Starting from Jeolla-do in the 30th year of King Sejong's reign, Gyeonggi-do and Chungcheong-do in King Sejo's reign, and Gangwon-do in the 9th year of King Seongjong's reign were implemented And in the 20th year of King Seongjong's reign and 59 years after the public opinion survey, the construction law was finally implemented nationwide after Hamgyeong-do Island. Although it had various problems until it was implemented, the construction method helped farmers improve their livelihoods, and the nation's finances became stronger due to the increase in stockpiles than ever before. It would have been possible to create a brilliant culture of the 15th century Sejong period because of this basis for the people and the country to find stability.
