During the Xia and Shang Dynasties, the country of ethnic minorities in Northeast China was called Fuyu, which was located in the present Songnen Plain. Now the ruins of Fuyu ancient city have been discovered in Youyi County, Heilongjiang Province. Sushen State was established in Shang and Zhou Dynasties, and Buji State was established by ethnic minorities in Northeast China in Han Dynasty. One of them is Xianbei, which originated in Inner Mongolia near Heilongjiang. During the Western Jin Dynasty, the Northern Wei Dynasty was established in northern China, which unified northern China. Later, the Northern Wei Dynasty was divided into the Eastern Wei Dynasty and the Western Wei Dynasty, and later unified into the Northern Zhou Dynasty. Emperor Wendi of the Northern Zhou Dynasty rebelled, overthrew the Northern Zhou Dynasty, established the Sui Dynasty, and unified southern China. During the Sui and Tang Dynasties, the dynasty in the northeast of China was the Bohai Kingdom, which was founded by Dalangrong, and was named the king of Bohai County during the reign of Emperor Xuanzong of the Tang Dynasty. At the end of the Tang Dynasty, the Khitans rose and established the Liao State. At the end of the Northern Song Dynasty, Nuzhen rose up and destroyed the Liao country, forcing the Khitans to move westward and establishing the Western Liao in western China. Jurchen founded the State of Jin and perished the Northern Song Dynasty. In the middle and late Southern Song Dynasty, the Mongols flourished, and Temujin, the tribal leader, destroyed the State of Jin and established the Mongolian khanate. Jurchen moved to the birthplace of Changbai Mountain. Jurchen in the Ming Dynasty was divided into four parts, among which, under the leadership of Nurhachi, the leader of the late Ming Dynasty, Jianzhou Jurchen issued the "Ten Hatred" imperial edict against Ming Dynasty and began to fight against Ming Dynasty. After the conquest of Shenyang, the name of the country was established and Shenyang was changed to Shengjing. Later, his fourth son, Huang Taiji, changed his nationality from "Nuzhen" to "Manchuria" and changed his title from "Jin" to "Qing" during his son the emperor shunzhi's period, thus unifying the whole country.
