Le Lang Competition in Le Lang County

According to the biography of the Three Kingdoms of Dongchuan, 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, the geographical records in the Book of Jin (Volume 14) record that "in October of the second year of Xianning (276), Changli, Liaodong, Xuantu, Daifang and other five counties were located in Pingzhou", "Lelang County, Han County, six counties, 3,700 households", and Yifang County and Gongsun Du County, four thousand households in seven counties. So in 247, Pyongyang and Dongchuan Wangsuo City should be the acropolis of domestic cities, not in Datong River. After the rebellion of the Eight Kings in the Western Jin Dynasty, the Central Plains was in chaos, and Koguryo began to oppress Lelang County in the south. In the twelfth year of Koguryo's spread to the king (AD 3 1 1), he seized Anping County (located on the north bank of the Yalu River estuary) and cut it off, and transferred Fanger County to Liaodong. Historical records of the three kingdoms Koguryo Biography records that 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. The former Yan Murong family was the last regime to create great things for Koguryo. In the winter of 342 AD, Murong Mu destroyed Goguryeo Capital Pill, but he could not restore China's previous control over Le Lang's homeland in the northern part of the Korean Peninsula, so he had to accept Goguryeo'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 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.

At the beginning of 3 13, according to Le Lang's records, Zhang Tong, who took Fangfang County, moved more than 1,000 households to Murong Hui in western Liaoning because he could not bear to fight alone with Goguryeo and Baekje for a long time, and Murong Hui later established Le Lang Overseas Chinese County in western Liaoning (Zi Jian, volume 88, the first year of Jianxing). However, the epitaphs and brick carvings of Han people with titles and titles in the Eastern Jin Dynasty found in Le Lang's hometown in the 4th century and the early 5th century show that from 3 13 to the early 5th century, Han people still lived in Le Lang's hometown and continued to work for the Eastern Jin Dynasty.
