Aigun

Aigun (simplified Chinese: 瑷珲; traditional Chinese: 璦琿; pinyin: Àihún; Manchu: ᠠᡳ᠌ᡥᡡᠨ ᡥᠣᡨ᠋ᠣᠨ Aihūn hoton) was a historic town of China in northern Manchuria, situated on the right bank of the Amur River, some 30 km south (downstream) from the central urban area of Heihe (which, in its turn, is across the Amur from the mouth of the Zeya River and Blagoveschensk).

The Chinese name of the town, which literally means "Bright Jade", is a transliteration of the original Manchu (or Ducher) name of the town.

Today the former city of Aigun is called Aihui Town (爱辉镇); it is part of Aihui District, which in its turn is part of the prefecture-level city of Heihe (and also includes downtown Heihe). Heihe is one of the major cities of Heilongjiang Province, People's Republic of China.
