Han Sijun and Koguryo

Koguryo originated in the northeast of China and is a local government in China. Among them, filth, Fuyu and Han nationality are the main groups, and a few Xianbei ethnic groups have been sinicized.

The History of the Three Kingdoms records that in 37 AD, King Wu attacked Le Lang County, south of Yalu River, and once occupied the county. Seven years later, Emperor Guangwu sent troops across the sea to seize the music waves and stopped the expansion of Koguryo. In February, 49, King Mu Ben sent generals to attack the four counties of Houhan, including Peiping, Yuyang, Shanggu and Taiyuan. Cai Tong, the governor of Liaodong, confronted King Muben with kindness and faithfulness, and restored the relationship between the two countries through close ties.

According to the biography of the Three Kingdoms, in the twenty-first year of King Dongchuan (247), "Wang Ducheng was unable to return to Beijing after the chaos, so he set up Yangcheng, immigrants and temples. Pyongyang, the hometown of the immortal Wang Jian, or Wang Xian, the capital of Wang Yun. " However, Volume XIV of the Book of Jin records in Geography: "In October of the second year of Xianning (276), Changli, Liaodong, Xuantu, Daifang and other five counties were located in Pingzhou", and "Lelang County, Han County, Six Counties and 3,700 households" were located in Fangfang County, Gongsun Du County, Seven Counties and 4,900 households. Historical records of the three kingdoms Koguryo Biography records that Koguryo "invaded Lelang County and captured more than 2,000 men and women". So in 247, Pyongyang and Dongchuan Wangsuo City should be the acropolis of domestic cities, not in Datong River. The traditional view is that 3 13 is the beginning of Koguryo Lelang County. According to the biography of the Three Kingdoms Koguryo, Koguryo "invaded Lelang County and captured more than 2,000 men and women." ; 4 1 year, the former king of the old country, "Baekje King led 30,000 troops to attack Pyongyang"; In the seventh year of Little Beast King Lin, "Baekje marched 30,000 troops into Pyongyang"; In four years, King Tukai opened the door, and he "fought Baekje in the water god". All these indicate that Koguryo has captured two counties and controlled the Datong River basin in the early 4th century. Koguryo is a local government in China. Koguryo itself is a multi-ethnic local political power, the main body of which is some ethnic groups in the northeast of China, including filth and Fuyu.

1. Korea was founded by Kiko, and Ji Zi was an aristocrat in Shang Dynasty, who led some people eastward to the northern part of the peninsula.

2. Jizi Korea was destroyed by Wei Man Korea, and Wei Man was a general of Yan State, so Wei Man Korea can be regarded as a "dynasty change" of local government.

3. Wei Man Korea was destroyed by the Han Dynasty, and most areas were annexed by the Han Dynasty, establishing "four counties of the Han Dynasty". This incident can be regarded as a turning point for the central government to directly control the Korean peninsula from the state of imprisonment.

The former Yan Murong family was the last feudal regime to give Goguryeo great creation. In the winter of 342 AD, Murong Mu destroyed Koguryo Capital Pill, but the central government was in chaos, and China could not restore its control over the northern part of the Korean Peninsula after the Han Dynasty, so it had to accept Koguryo's submission. History as a Mirror, volume 97, one year after the former king of the old country, Qian Yan, attacked Koguryo, "sent his brother Yu Yan, a vassal, to the DPRK, with thousands of tributes and treasures." Under the military pressure of Yan Qian, Koguryo moved to Pyongyang.

In 37 1 year, Prince Baekje led 30,000 troops to win Le Lang and killed the former Koguryo king. Baekje won Le Lang in a short time. King Tai Hao and Wang Changshou of Koguryo defeated Baekje many times, and the Baekje army was expelled from Lelang County. Around 427 AD, Baekje continued to fight for control of Le Lang and Fangfang counties.
