Korea is a big immigrant country.

The ancestor of the Korean generation (Koreans) is the Sanhan tribe in the southern part of the peninsula. Three Han tribes, Baekje and Silla, developed, occupying only the southern part of the peninsula. Koguryo, contemporary with Baekje and Silla, is a country founded by Koguryo people in mainland China. Koguryo's name comes from Koguryo County under the jurisdiction of the Han Dynasty. At that time, the northern part of the peninsula was the territory of the Han Dynasty, and Koguryo was a vassal state of the Han Dynasty. Koguryo's territory was only accepted after the Western Jin Dynasty and became the master of the northern peninsula. At this time, Koguryo has entered the late dynasty. In the end, Koguryo was destroyed by the Tang Dynasty, and the northern border of the peninsula was taken over by the Tang Dynasty. Of course, the Sui Dynasty levied Goguryeo three times without success. The northern part of the peninsula has always been the territory of the mainland nationalities. Shang Dynasty, Yan State, Qin Dynasty, Han Dynasty, Western Jin Dynasty, Koguryo, Tang Dynasty, Bohai Sea, Qidan and other nationalities are all mainland nationalities, and they all owned the northern territory of the peninsula for more than 2,000 years. Koreans (Koreans) really owned the northern territory of the peninsula after Qidan, that is, after Wang Jian established the Korean kingdom.

However, modern Koreans (Koreans) only regard Koguryo as their ancestors. Why don't other businessmen, Yan people, Qin people, Han people, Western Jin people, Tang people, Bohai people and Qidan people who own the northern border of the peninsula recognize their ancestors? Because Koguryo people have disappeared from other ethnic groups, they say that Koguryo people are their ancestors and are more likely to break the contract! ! In addition, Wang Jian, the ancestor of Silla Koreans, established the Korean dynasty to replace Silla more than 200 years after Goguryeo's death. The extinct Koguryo was called Koryo in the Tang Dynasty. But Wang Jian himself is not a descendant of Goguryeo. Korean history books say that he built his kingdom into a powerful country like Koguryo in the name of North Korea. It is this Wang Gaoli who makes Koreans (Koreans) think of themselves as Koreans. This is how Sanhan people became Koreans. However, this Korean nation and Koguryo nation are simply two different nations. But Koreans (Koreans) deliberately associate their own Koryo with Koguryo, so they are so stubborn!

The real kingdom of Koguryo is composed of mainland nationalities, and the aristocratic class is Koguryo, and most of Koguryo immigrated to the Central Plains of the Tang Dynasty after the demise of Koguryo in the Tang Dynasty.

China's history books refer to Korea built by Kiko of Shang Dynasty. Later, Wei Man, a native of Yan State, replaced the descendants of Ji Zi and established Wei Man's Korea. Koreans had never established a country called Korea before Lee Korea in the14th century. However, China's history books record the Korean nation established on the mainland before Lee's Korea in the14th century. In A.D. 1392, Wang Dachen abolished the king. 1393 was called the King of Korea in the Ming Dynasty, and Wang was renamed Korea. Scholars generally called Li Dynasty or Li Dynasty. This is how three Koreans became North Korea!

Before the 20th century, the Sanhan people had a long history of advanced continental dynasty culture because of the weakness of the country. Moreover, the elites of Sanhan people are all educated by China culture, so they regard China's history books as their ancestors, thus erasing their ancestry as foreigners. Emperor China was certainly willing to accept such "relatives". This view of history misled the two countries.

After the three Koreans broke away from Japanese rule, nationalism rose. In order to get rid of the connection between history and culture and the China Dynasty, they fabricated a 5,000-year-old civilization and regarded it as their own history and country.
