At the beginning of Chen Mai's rule, he worked hard to build a city and set up a department, and at the same time handled military affairs seriously. At that time, the security situation of Fuqing Suanling, Yingxian Post (now Shishi Village, Jiangkou Town), Wudiandian (now Songdong Village, Wutang Town) and Baidu Village (now Baidu Natural Village, Baixi Village, Xiwei Town) was not good, and business travelers were often robbed by hundreds of people. Chen Mairen dealt with it severely and took decisive measures to improve the public security situation and smooth the road. He attaches great importance to agriculture, building water conservancy and developing production, so the crops are harvested every year. He also attaches importance to the development of transportation and promotes the exchange of materials between urban and rural areas; With the establishment of the school and the development of education, Lang Lang's books spread all over the country, laying the foundation for "a famous literary country", "Zou Lu by the sea" and "Hulan Xiong Yi". Chen Mai also attached importance to cultural relics and built the Yuewangtai ... So the society was stable, the population increased, the productivity continued to develop, and the tax paid increased year by year, making Putian a top 100 county.
