How should contemporary college students strengthen their own ideological and moral construction? This is a problem. In my opinion, to strengthen ideological and moral construction, we need to start from the following aspects. First, we should pay attention to the study of basic theories and basic viewpoints. Mao Zedong said: "Socialism is like a banner." Scientific theory is like a banner, guiding thousands of troops to charge towards the right goal. To strengthen ideological and moral construction, we must first study the basic theories and viewpoints of ideological and moral construction, master its spiritual essence, truly realize the inevitability of China taking the socialist road from the depths of our thoughts, truly realize that the life values advocated by our society with collectivism as the core are consistent with the ultimate value goal of the unity of truth, goodness and beauty in human society, and truly realize the value of this life values. This is the basis of strengthening ideological and moral construction, which is of great significance for improving college students' theoretical quality and ability to understand, analyze and solve problems, and for establishing a scientific world outlook, outlook on life and values. Second, we should pay attention to integrating theory with practice and learn from comparison and identification. To strengthen ideological and moral construction, young college students should not only master the basic theories and viewpoints of ideological and moral construction, but also pay attention to using these viewpoints, analyze and understand practical problems, integrate theory with practice, and learn through comparison and identification. This is especially important for contemporary college students who are in the period of social transformation and face the dilemma of multiple value system selection. Integrating theory with practice includes two aspects, on the one hand, connecting with the social reality of reform and opening up, on the other hand, connecting with one's own ideological reality. Comparative study mainly means that young students should learn to use the theories they have learned, analyze and understand the complicated political, economic, cultural and moral phenomena in real social life, compare and evaluate various social thoughts and values, and choose and establish Socialism with Chinese characteristics's political direction and scientific world outlook, outlook on life and values through analysis and comparison. Third, we should pay attention to the unity of knowing and doing, and learn while doing. The unity of knowledge and practice and the emphasis on practice are determined by the characteristics of ideological and moral construction. College students know the basic theory of ideological and moral construction through study and discussion, which is called "knowledge". However, acquiring knowledge is not the ultimate goal of strengthening ideological and moral construction. The purpose of acquiring knowledge is "doing" and "practicing". Ancient thinkers in China have long pointed out that "no talent is true knowledge". Therefore, the integration of knowledge and practice and the emphasis on practice have become the focus of strengthening ideological and moral construction. This requires college students to pay attention to the unity of knowing and doing, insist on starting from themselves, start from now on, learn and practice, further deepen their understanding and understanding of "knowledge" in practice, truly achieve the unity of knowing and doing, constantly improve their ideological and moral realm, and realize their goals.
