Yuan Chonghuan
Yuan Chonghuan, courtesy name Yuansu, art name Ziru, was a Chinese politician, military general and writer who served under the Ming dynasty. Remembered as a national hero of Ming China and widely regarded as a culture hero in Chinese culture, he is best known for defending Liaoning from invasions launched by the Jurchen-led Later Jin dynasty. As a general, Yuan Chonghuan excelled as a cannoneer and sought to incorporate European cannon designs into the Ming arsenal.
Liaodong Peninsula
The Liaodong or Liaotung Peninsula is a peninsula in southern Liaoning province in Northeast China, and makes up the southwestern coastal half of the Liaodong region. It is located between the mouths of the Daliao River in the west and the Yalu River in the east, and encompasses the territories of the whole sub-provincial city of Dalian and parts of prefectural cities of Yingkou, Anshan and Dandong.
Manchuria
Manchuria is a historical region in northeast Asia encompassing the entirety of present-day northeast China and parts of the modern-day Russian Far East south of the Uda River and the Tukuringra-Dzhagdy Ranges. The exact geographical extent varies depending on the definition: in the narrow sense, the area constituted by three Chinese provinces of Heilongjiang, Jilin, and Liaoning as well as the eastern Inner Mongolian prefectures of Hulunbuir, Hinggan, Tongliao, and Chifeng; in a broader sense, historical Manchuria includes those regions plus the Amur river basin, parts of which were ceded to the Russian Empire by the Manchu-led Qing dynasty during the Amur Annexation of 1858–1860. The parts of Manchuria ceded to Russia are collectively known as Outer Manchuria or Russian Manchuria, which include present-day Amur Oblast, Primorsky Krai, the Jewish Autonomous Oblast, the southern part of Khabarovsk Krai, and the eastern edge of Zabaykalsky Krai.
