More than 3,000 years ago, when the Shang Dynasty perished, Ji Zi, a noble of the Shang Dynasty, led 5,000 people who didn't want to be courtiers of the Zhou Dynasty to flee to the east and set up securities on the Datong River. They think this place is in the east of China, and it receives sunlight earlier than China, so it is named North Korea, which means Asahi Shining. The city they built on the edge of the Datong River is called Pyongyang, which means the land is flat. Ji Zi was a great saint. He educated 5,000 people with China culture and turned North Korea into a country of gentlemen in the East. Jizi Korea has existed for 1000 years. Later, it was overthrown by Wei Man of the Han Dynasty. Wei Man became king in Pyongyang and established Wei Man Korea. 100 years later, Seoul marched eastward, destroyed North Korea, and established four counties, with Pingyang as the county and Lelang County around it. Since then, the word Korea has been called an archaic or place name, not a country name.

North Korean locals call themselves "Han", which means "Da" when translated into Chinese.

The Qin dynasty was cruel, and people fled everywhere to escape tyranny. Many people fled to the southeast of the Korean peninsula and gathered in Busan today, which was called "Qin and Han Dynasties" in history.

After the demise of the Han Dynasty, the Jin Dynasty was in turmoil and lost its northern territory. The "Qin and Han" factions in the southeast of the Korean Peninsula fought and annexed each other. In the end, one of them, Silla, wiped out all forces and took control of the southeast of the Korean Peninsula. At that time, a branch of the northern Fuyu Kingdom occupied Koguryo County in China, established the Koguryo Kingdom, and later invaded the Korean Peninsula and occupied Pyongyang, taking it as its capital. Baekje countries have also appeared in the southwest of the Korean peninsula. This is the "Three Kingdoms" period of North Korea.

Silla United with the Tang Dynasty and wiped out two other countries. Baekje belongs to Silla, Koguryo Liping is divided into two parts, Datong belongs to Tang in the north and Silla in the south. Because Pyongyang is in the north of Datong River, it is the border town of the Tang Dynasty.

Silla was followed by North Korea, with Kaesong in the south of Pyongyang as its capital.

North China was originally a country of, but later it was controlled by Mongolia and gradually became a pro-Mongolian security, which made patriotic officials and people very disgusted. After China drove away the Mongols in the Ming Dynasty, Li Chenggui, a patriotic general of North Korea, overthrew the pro-Mongolian securities and established the pro-China securities with the support of the people. And pay tribute to China, and ask the name of the country. At that time, Emperor Zhu Yuanzhang gave it the name of Korea, hoping that they could promote the advanced Korean culture like Jizi Korea, and be called a civilized country. So Li Chenggui established Korea. Historically, it was called "Lee Korea" and Jizi Korea was called "Ancient Korea".

North Korea initially set Kaesong as its capital, but later decided that Hanyang County on the Han River had a good geographical location, so it moved to Hanyang. Therefore, China people call the capital of South Korea "Seoul" to distinguish Hanyang and Hubei in China.

Koreans call the capital "the capital", which is the origin of "Seoul" now.
