According to the Civil Service Law of People's Republic of China (PRC), civil servants should receive corresponding initial training before taking up their posts. Initial training includes public subjects and professional subjects. Public subjects include civil servants' professional ethics, code of conduct, national security, national defense and army building, and professional subjects include civil servants' professional knowledge and ability.

In addition, according to the Organic Law of Local Government in People's Republic of China (PRC), the people's governments of provinces, autonomous regions and municipalities directly under the Central Government are led by governors, chairmen of autonomous regions, mayors and county heads respectively. Therefore, the mayor, as a member of the local government, needs to receive the corresponding initial training before assuming the post of mayor.

It should be pointed out that the procedures for the appointment and training of mayors may vary according to regions and specific situations.
