According to China Local Records Network, local records are compiled every 20 years. Because local chronicles are informative documents that comprehensively and systematically describe the history and present situation of nature, politics, economy, culture and society in this administrative region, they have certain timeliness. With the passage of time, social, economic, cultural and other aspects will change and need to be revised regularly to ensure the accuracy and integrity of local chronicles.

After the completion of each round of compilation and revision of local chronicles, local chronicles working institutions will start a new round of compilation and revision of local chronicles while compiling local comprehensive yearbooks, collecting data and providing local information consulting services to the society.
