In the five years of practice since the Eighteenth National Congress, our Party has formed Xi Jinping's thought of new-era socialism with Chinese characteristics. According to CPC's plan, colleges and universities must integrate Xi Jinping's new-era socialism with Chinese characteristics and the spirit of the Nineteenth National Congress of the Party into their course books and classroom teachings, so as to achieve the goals of instilling the latest major theoretical achievements into students' mind, namely, the so-called "three enters". In this process, teachers of ideological and political theory in colleges and universities must well develop theories into course materials, course materials into classroom teachings and classroom teachings into value systems. Meanwhile, they should have good understanding of the value, principle and practical basis for the "three enters" work, and strive to reveal the ideology behind the theory, the strategy behind the ideology and the wisdom implied in the strategy, thus truly realize the goal of instilling new ideas and theories into students' mind.
