In 1927, when the Nationalist Party under Chiang Kai-shek established a republic, they also established a list of urgent duties. One was to reform the government structure from top to bottom so as to show the rest of the world its capability to govern the country in a modern way. While big cities were the showplaces for modernization and state-building, down at the county level, Chiang Kai-shek proclaimed Zhongshan in Guangdong the “model county.” To maintain this honor and its benefits, the local authorities made special efforts to restructure the government; reforming and retraining the police force was one important aspect of this attempt. While it is commonly held today that in the 1930s and 1940s county governments in the Pearl River Delta had disintegrated and were dominated by “local bosses,” this article uses previously inaccessible local records to examine Zhongshan County government and reform to answer one particular question: whether Zhongshan was successful in forming a modern police force. It examines a number of problems related to inefficiency and ineffectiveness in government administration, but at the same time also discusses why many civilians were welcoming, rather than suspicious, of the police. The answers to these issues suggest that the overall structure and management of the Zhongshan government (and even social integration) was to some extent consolidated in this period.
