Manchu language
Manchu (ᠮᠠᠨᠵᡠ ᡤᡳᠰᡠᠨ Manju gisun) is a critically endangered Tungusic language native to the historical region of Manchuria in Northeast China. As the traditional native language of the Manchus, it was the national language of the Qing dynasty (1644–1912) of China, although today the vast majority of Manchus speak only Mandarin Chinese.
