Where did Manchu people of Qing Dynasty in China come from now?

Manzhouli in a narrow sense refers to three northeastern provinces, namely Liaoning, Jilin and Heilongjiang, or four northeastern provinces (including Chifeng City, Xing 'an League, Tongliao City, Xilin Gol League and Hulunbeier City in eastern Inner Mongolia).

Manchuria, Liaodong, Guandong, Guanwai and Northeast successively inherited the relationship, but the specific geographical scope was very different. During the Spring and Autumn Period, Yan established Liaodong County and Liaoxi County in the northeast. After Qin Shihuang unified China, Liaodong County was established in Yan State. The general scope is a part of Liaoning Province today, and the eastern starting point of Qin Changcheng is Liaodong.

In the 14th year of Hongwu in Ming Dynasty (A.D. 138 1), General Xu Da built Shanhaiguan, and from then on, the territory of Northeast China was called Kanto and Guanwai. On October 13th, the 9th year of Tiancong (1635), Huang Taiji issued a letter to change his surname to Manchuria, which is both a surname and a geographical concept. Since then, the territory of Northeast China has been called Manchuria.

Historically, Manchuria (Northeast China) has a broad sense and a narrow sense. Manchuria in a broad sense refers to all the territory of the Qing Dynasty in the northeast before the Sino-Russian Nebuchadnezzar Chu Treaty. Generally speaking, it reaches Lake Baikal, Yenisei River and Lena River in the west, Shanhaiguan in the south, the Pacific Ocean in the east and the Arctic Ocean in the north, covering the entire coastline of Northeast Asia, including Chukchi Peninsula, kamchatka peninsula, Sakhalin Island and Thousand Islands.

Liaodong is a geographical concept of southern Manchuria, which was once used to refer to the vast Manchuria region. In history, Liaodong once included Hansi County (most of the area north of the Hanjiang River Basin on the Korean Peninsula).

Extended data

Banners in Qing Dynasty were divided into "Buddha Manchuria" and "Che Yi Manchuria". (Both of them are Northeast natives) "Buddha" means "old" in Manchu; "Che Yi" means "new" and refers to the Mongolian flag and Han flag newly incorporated into the Eight Banners.

There are many differences between Fo Manchuria and Fo Manchuria: Fo Manchuria set up an army together with Nurhachi and Huang Taiji, made up flags earlier, and had more fighters with the Qing army before entering the customs; Manchu Banner in Che Yi was compiled late, and most of them entered the flag with the development of the fighting society in western Liaoning. Most of them were Han and Mongolian, living in Horqin Banner and Chahar Banner. Che Yi Manchuria continued to intermarry with Buddha Manchuria and gradually merged into one. Customs are different from those in Buddha Manchuria, and they are more nomadic.
