Culture is a unique phenomenon in human society, which reflects the wisdom of human beings. It is not only the core of a country's cohesion, but also the spiritual driving force for a country to be prosperous and developed. Cultural confidence is an important theoretical content and component of Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era, and an essential source of strength for the great rejuvenation of the Chinese nation. Under the influence of foreign cultures, college students in the new era have problems such as loss of value and lack of confidence in terms of cultural confidence. Therefore, in the course of expanding foreign exchanges and carrying out reform and opening up, it has become an important mission that cannot be delayed for the ideological and political theory teaching in colleges and universities to strengthen the cultural confidence of college students and reinforce their cultural confidence education.
