In the twenty-eighth year of Hongwu (1395), in the revised "Emperor Ming Zu Xun", Zhu Yuanzhang established 15 countries that were not to be conquered, namely:
Northeast:
The state of Korea (i.e., Goryeo. His Li Renren, and his son Li Chenggui are now famous, from the sixth year of Hongwu to the twenty-eighth year of Hongwu, the first and last of the four kings of the Wang family, so treated)
North-east:
Japan (although the dynasty is really deceitful, the secret adulterous minister Hu Weiyong, plotting to do wrong, so it is absolutely unlikely)
East-south:
Great Ryukyu Kingdom (from time to time, the sons of princes and courtiers are all enrolled in Taixue to study, and they are very courteous)
Xiaoliuqiu Kingdom (no way to come, no tribute)
Southwest:
Annan Kingdom (triennial tribute)
Chenla country (tributary as usual, its country is on the coast)
暹罗国（朝贡如常，其国滨海）
Champa (Since the countries below the city of Zhancheng came to pay tribute, they brought merchants inside, and many deceitful acts, so they were frustrated. From the eighth year of Hongwu to the twelfth year of Hongwu, Fang Nai stopped. Coastal City)
Sumatra (its country's coastal area)
Western country (its country of the sea)
Jawa (its country resides in the sea)
The Kingdom of Hangheng (whose country resides in the sea)
White Flower Country (its country resides in the sea)
The Kingdom of Sanfuqi (whose country resides in the sea)
Bo Ni Country (its country resides in the sea)
So what are these 15 countries doing now?
1. North Korea
The state of Korea is now North Korea. In the 25th year of Hongmu (1392), Yi Sung-gye overthrew the Goryeo Dynasty and established himself as the king, creating the Joseon Dynasty. In order to win the support of the Ming Dynasty, Li Chenggui referred to the ancient name of Goryeo "Joseon" and the place where Li's father was located "Hening", and sent an envoy to ask Zhu Yuanzhang, Taizu of the Ming Dynasty, to rule on the name of the country. Zhu Yuanzhang believed that "North Korea" was an ancient name, and the origin of "Asahi distinct" was elegant, so he ruled that North Korea was the new national name. Beginning with Yi Sung-gye, the Yi dynasty ruled Korea for more than 500 years until it was annexed by Japan in 1910.
North Korea
After Japan surrendered unconditionally in 1945, Kim Il Sung intended to unify the Korean Peninsula, but the Korean War broke out, and in 1953 the Korean Armistice Agreement was signed, and the Korean Peninsula was divided into two countries, North Korea and South Korea.
Today, the DPRK is one of only five socialist countries in the world, which pursues a foreign policy of "independence, peace, and friendship" and advocates the development of foreign relations in accordance with the principles of complete equality, independence, mutual respect, non-interference in each other's internal affairs, and mutual benefit. Relations with the mainland are also relatively good.
2. Japan
Japan is now Japan, and it has a deep relationship with the mainland in history, and it has also caused the most harm to the mainland. Especially in the last years of the Qing Dynasty, Japan gradually became rich and powerful through the Meiji Restoration. Taking advantage of the corruption of the Qing Dynasty, Japan took the opportunity to invade the mainland, from the First Sino-Japanese War to the September 18 Incident and then to the full-scale invasion of China, causing great harm to the mainland.
After Japan announced its unconditional surrender in 1945, the world soon entered a period of hegemony between the United States and the Soviet Union, and Japan, with the connivance of the United States, quickly changed from the post-war era and became one of the richest countries in the world in just over a decade. Today, Japan is still one of the most powerful countries in the world. However, Japan is still hurting the world, especially last year's discharge of nuclear wastewater into the sea, which caused great harm to the world.
Japan
When Zhu Yuanzhang established Japan as a country not to be conquered, he also attached a sentence, saying that although the dynasty was really deceitful, he secretly committed adultery with Hu Weiyong, and plotted to do wrong, so he was absolutely abandoned. Literally, it means that Japan is implicated in the Hu Weiyong case and has the intention of rebellion, but in fact it is an excuse for Zhu Yuanzhang to take back power. In addition, Japan at that time was a barren land in the eyes of Zhu Yuanzhang, and there would be no loss if it was not obtained, and it was difficult to effectively control it if it was obtained. As he himself said, "All the four sides are confined to mountains and seas, and they are secluded in a corner, and the land is not enough to supply, and the people are not enough to give orders." ”。
3. The Great Ryukyu Kingdom and the Lesser Ryukyu Kingdom
The core of the Great Ryukyu Kingdom was present-day Okinawa, Japan. Historically, Ryukyu had a very close relationship with China, participating in the tribute system of the Ming Dynasty and still maintaining its status as a vassal state during the Qing Dynasty. The Lesser Ryukyu Kingdom refers to Taiwan, which is named after the proximity between Taiwan and the Ryukyu Islands.
Ryukyu Islands
In 1609, the Satsuma clan of Japan invaded the Ryukyus and forced the Ryukyus to pay tribute to Japan. The Ryukyu Kingdom was formed into a state of "two genera", and gradually came under the de facto control of the Satsuma Domain, becoming a vassal of the Satsuma Domain. In 1872, the Japanese government took advantage of the Meiji Emperor's personal administration to cut the name of Ryukyu Kingdom and set it as the "Ryukyu Domain". In July 1875, Japan forced the Ryukyu Kingdom to stop paying tribute to the Qing government and switch to the Japanese era name. In 1879, Japan announced that the Ryukyus would be abolished and the prefectures would be abolished, and the so-called "Ryukyu Disposal" was completed, and the Ryukyus were forcibly incorporated into Japan and "Okinawa" Prefecture was established, and the Ryukyu Kingdom collapsed
4. Annan Country
Annam is now the north of Vietnam, Annam from the 3rd century B.C. China Qin Dynasty began to become Chinese territory, to the five dynasties and ten kingdoms when Wu Quan divided Annam, the Ming Dynasty Hongwu in the last years, Annam rebellion broke out. During the Yongle period, Zhu Di, the ancestor of the Ming Dynasty, sent a large army to conquer Annan, changed Annan to Jiaozhi, set up three divisions, fifteen prefectures, and governed 36 prefectures and 181 counties. During the Xuande period, Ming Xuanzong comprehensively contracted and abandoned Annam, and Annam became completely independent, and Vietnam existed as a vassal state of China for a long time thereafter.
Vietnam
Today's Vietnam is one of the five socialist countries in the world, and in the seventies and eighties of the last century, Vietnam's self-confidence was inflated, and it dared to oppose the mainland. After the war, Vietnam also carried out reform and opening up, and is a member of the Association of Southeast Asian Nations, the Asia-Pacific Economic Cooperation Organization, and the World Trade Organization, and is a founding member of the Asia-Europe Meeting and one of the 11 countries in the future.
5. Zhenla country
In the fifth year of Xuande of the Ming Dynasty (1430), Siam invaded the Khmer Empire, besieged Angkor for seven months, and finally broke through Angkor. Because Angkor was too close to the Siamese border, the Khmer Empire abandoned Angkor and moved its capital to Phnom Penh. Since then, the country has been referred to as Cambodia in Chinese historical documents.
Cambodia
In 1863, Cambodia became a French protectorate. In September 1940, it was occupied by Japan, and on November 9, 1953, independence was declared. Since the 70s of the 20th century, Cambodia has experienced a long war. In 1993, with the establishment of Cambodian state power institutions and the realization of national reconciliation, Cambodia entered a new era of peace and development. But it is still one of the poorer countries in the world.
6. Siam
In 1377, Ming Taizu Zhu Yuanzhang canonized King Ayutthaya as the "King of Siam", and Siam officially became the name of Thailand in the Chinese context. In the middle of the 14th century, the Thai leader Utong King annexed the territory of the Sukhothai Kingdom and established the Ayutthaya Dynasty (Ayutthaya Dynasty), and by the middle of the 18th century, its territory extended to Nakhon Ratchasima and Chanthaburi in the east, Pattani in the south, Tanah Salin and Dawei in the west, and Lannathay in the north was also subject to it. On June 24, 1939, the country was renamed "Thailand", renamed "Siam" in 1945, and renamed "Thailand" again in 1949.
Siam
Today, Thailand is one of the newly industrialized countries and market economies, and has a liberal economic policy and is an export-oriented economy. It is a member and founding member of ASEAN, located in the center of ASEAN, with a relatively stable society, a high degree of policy transparency and trade liberalization, an open and inclusive business environment, and is the second largest economy in ASEAN.
7. Boni country
At the beginning of the founding of the country, it only owned the land near the port of Brunei in the north of Kalimantan Island, and then gradually expanded, and by the beginning of the Ming Dynasty, it had possessed most of Kalimantan Island and the southern islands of the Philippines. At the end of the 16th century, due to the decline of the state due to the strife within the royal family, Western colonists took the opportunity to invade. In 1888 it became a British protectorate.
Brunei
Brunei, which is now Brunei, signed a contract with Britain in 1971 to gain autonomy except for foreign affairs and defence matters. It became fully independent on 1 January 1984 and joined ASEAN on 7 January of the same year. Brunei is a small country with a strong economy, with the 5th highest GDP per capita in Asia in 2014, and the second in Asia outside the Gulf region (after Singapore).
In addition to the above-mentioned countries, the remaining countries are no longer there, the Champa state is now southern Vietnam, in 1693, Nguyen Youjing led a large-scale invasion, captured the king and the royal ministers, and in 1697 was destroyed by the state of Annam. Sumatra is the present-day Sumatra island of Baxi, the Western country is the current Coromandel coast, the Java country is the present-day Java Island, the Huheng country is the present-day Malay Peninsula, the white flower country is the northwestern part of the present-day Sumatra island, and the Safuqi country is the present-day Sumatra island Palembang.
