Treaty of NerchinskThe Treaty of Nerchinsk () of 1689 was the first treaty between the Tsardom of Russia and the Qing dynasty of China. The Russians gave up the area north of the Amur River as far as the Stanovoy Range and kept the area between the Argun River and Lake Baikal. This border along the Argun River and Stanovoy Range lasted until the Amur Annexation via the Treaty of Aigun in 1858 and the Convention of Peking in 1860. It opened markets for Russian goods in China, and gave Russians access to Chinese supplies and luxuries.
Tungusic peoplesTungusic peoples are an ethno-linguistic group formed by the speakers of Tungusic languages (or Manchu–Tungus languages). They are native to Siberia and Northeast Asia. The Tungusic phylum is divided into two main branches, northern (Evenic or Tungus) and southern (Jurchen–Nanai). An intermediate group (Oroch–Udege) is sometimes recognized. The name Tungusic is artificial, and properly refers just to the postulated linguistic phylum (Tungusic languages). It is derived from Russian Tungus (Тунгус), a Russian exonym for the Evenks (Ewenki).

Kangxi EmperorThe Kangxi Emperor (4 May 1654 – 20 December 1722), also known by his temple name Emperor Shengzu of Qing, personal name Xuanye, was the third emperor of the Qing dynasty, and the second Qing emperor to rule over China proper, reigning from 1661 to 1722. The Kangxi Emperor's reign of 61 years makes him the longest-reigning emperor in Chinese history (although his grandson, the Qianlong Emperor, had the longest period of de facto power, ascending as an adult and maintaining effective power until his death) and one of the longest-reigning rulers in history.
Manchu languageManchu (Manchu:, Romanization: manju gisun) is a critically endangered East Asian Tungusic language native to the historical region of Manchuria in Northeast China. As the traditional native language of the Manchus, it was one of the official languages of the Qing dynasty (1636–1912) of China, although today the vast majority of Manchus speak only Mandarin Chinese. Several thousand can speak Manchu as a second language through governmental primary education or free classes for adults in classrooms or online.
