Bei'an (Chinese: 北安; pinyin: Běi'ān; lit.

'northern peace') is a county-level city in west-central Heilongjiang province in the People's Republic of China.

Bei'an received the unofficial moniker of "Gun City" because it was the location of Factory #626; Factory #626 mainly manufactured Chinese clones of WW2 firearms and Type 56 rifles.

Six years later, a museum detailing the history of Factory #626 opened.
