In 1913 Aigun became the county seat of the newly created Aigun County (瑷珲县, Aihun xian), which was in December 1956 renamed Aihui County (爱辉县). On November 15, 1980, Heihe City was created, and on June 6, 1983, Aihui County was abolished, being merged into the Heihe City.
To further complicate the situation, in 1993 the former Heihe City (a county-level administrative unit) was reorganized into Aihui District (also a county-level unit), while the former Heihe Prefecture (黑河地区) became Heihe Prefecture-level City (which consists of Aihui District and a number of counties). This administrative division has been in effect ever since.
