Dang'an (simplified Chinese: 档案; traditional Chinese: 檔案; pinyin: dàng'àn) is a Chinese word meaning "record". Used in the political and administrative context, it means an archival system that records the "performance and attitudes" of citizens of mainland China. Together with the hukou, it has been an important part of the government's efforts to maintain control of its people. Majority of the records are kept by the local archive bureaus, some by the State Archives Administration of China at the national level.
The Dang'an includes personal information such as physical characteristics, employment record, photograph, etc. However, it also contains many other documents that would be considered private in some other cultures. According to Wang Fei-ling and other sources, this includes appraisals by supervisors and peers, academic reports from primary school to university, professional credentials, any criminal convictions or administrative penalties, club/society memberships, employment records and political history (such as Youth League and CPC membership and assessments). Some of the material is composed by the subject. Even the death certificate and eulogy may be placed in the file.
There are two copies for adults: one held on behalf of their work unit by its supervisory organization, and the other at the local Public Security Bureau (PSB). Access to dang'an is strictly controlled. Citizens do not usually see their dang'an, although they may ask a Communist Party member to check it for them. Alterations may only be carried out by special cadres, and when combined with the custom of guanxi the result is that "Personal revenge, false entries and special favors are thus part of the game."
