The training and study of young and middle-aged cadres at county level after graduation is not only a kind of accomplishment of leading cadres, but also a kind of responsibility. The focus of cadre training is to serve the cause of the party and the state and the healthy growth of cadres. The fundamental point is to be problem-oriented and focus on what is being done, so as to improve the ability of cadres to use the theoretical knowledge they have learned to guide practice, solve problems and promote work.
