A report on Hebei, Inner Mongolia and Manchu people

Liaoning is also known in Chinese as "the Golden Triangle" from its shape and strategic location, with the Yellow Sea (Korea Bay and Bohai Sea) in the south, North Korea's North Pyongan and Chagang provinces in the southeast, Jilin to the northeast, Hebei to the southwest, and Inner Mongolia to the northwest.

Between 1467 and 1468, the wall was expanded to protect the region from the northeast as well, against attacks from Jianzhou Jurchens (who were later to become known as the Manchu people).

(most often) Northeast China, specifically the three provinces of Heilongjiang, Jilin, and Liaoning, but broadly also including the eastern Inner Mongolian prefectures of Hulunbuir, Hinggan, Tongliao, and Chifeng, and sometimes Xilin Gol;

Greater Manchuria, the region of Northeast Asia that served as the historical homeland of the Jurchens and later their descendants Manchus, which was controlled in whole by China before the Amur Annexation in 1860. The region was since then divided between China (Northeast China, also known as "Inner Manchuria") and Russia (the Amur drainage basin that is located south of the Uda River and Stanovoy Range, which is now comprised the southern part of the Russian Far East. Also known as "Russian Manchuria", "Outer Northeast" or "Outer Manchuria");

Manchukuo (1932–1945), a puppet state of Imperial Japan. Its occupied territories included the entire Northeast China, the northern fringes of present-day Hebei Province, and the eastern part of Inner Mongolia.

Nevertheless, its built-up area, the third largest in China after Guangzhou and Shanghai, is slightly bigger, including three districts in Hebei (Sanhe, Dachang Hui and Zhuozhou) being conurbated but with Miyun and Pinggu Districts in Beijing not agglomerated yet.

In 938, after the fall of the Tang, the Later Jin ceded the frontier territory including what is now Beijing to the Khitan Liao dynasty, which treated the city as Nanjing, or the "Southern Capital", one of four secondary capitals to complement its "Supreme Capital" Shangjing (modern Baarin Left Banner in Inner Mongolia).

The capture of Beijing by Li Zicheng's peasant army in 1644 ended the dynasty, but he and his Shun court abandoned the city without a fight when the Manchu army of Prince Dorgon arrived 40 days later.

Shanxi borders Hebei to the east, Henan to the south, Shaanxi to the west and Inner Mongolia to the north.

The population is mostly Han Chinese with minorities of Mongol, Manchu, and the Hui.
