The principle of "four modernizations" of cadres refers to the principle of revolutionization, youthfulness, knowledge and specialization of cadres, and is the fundamental guiding principle of cadre work in the new period. Carrying out this policy in an all-round way is of great significance to promoting the construction of leading bodies and cadres and ensuring the smooth progress of reform, opening up and socialist modernization in terms of organization. The premise of the "four modernizations" of cadres is revolutionization. Revolutionary mainly refers to the political direction, political position, political morality and ideological style of cadres. In the period of socialist modernization, there are two basic requirements for the revolutionization of cadres, especially leading cadres: first, loyalty to Marxism and adherence to the party's basic theory and line; Second, we have the spirit of serving the people wholeheartedly and selflessly, honesty, diligence, fairness and integrity. This is the main symbol to measure the revolutionary degree of cadres. Only by persisting in revolutionization can we adhere to the correct political direction and unswervingly advance along the road of building Socialism with Chinese characteristics. Therefore, we must realize youthfulness, knowledge and specialization on the premise of revolutionization. "Younger" means that cadres should be young, energetic, healthy and competent for stressful and hard work. Younger cadres means to form a reasonable age structure and always maintain the fighting capacity and vigorous vitality of cadres. For the whole cadre team, it is necessary to train and bring up millions of successors to the socialist cause and realize the cooperation and alternation between new and old cadres. For leading bodies at all levels, it is necessary to form a trapezoidal age structure with young and middle-aged cadres as the main body to make the leading bodies more energetic and energetic. The revolutionization, youthfulness, knowledge and specialization of the cadre team embodies the unity of the requirements for cadres' morality, talent, knowledge and physique, and all of them are indispensable. Having both ability and political integrity is an all-round requirement for cadres, while morality is mainly a requirement for cadres' ideological politics and work style, mainly for cadres' ability and level. Party constitution's six requirements for leading cadres at all levels are the embodiment of the principle of having both ability and political integrity. The principle of having both ability and political integrity is also a complete unity, which cannot be separated or neglected. But compared with talent, virtue comes first. Only under the guidance of the correct political direction can the intelligence and wisdom of cadres better serve the people's cause. Therefore, when selecting cadres, we must first master politics, and at the same time, we must examine whether there are real talents and practical learning. 0 Respondents: Dragonair rookie-Gao
