Human society has entered 2 1 century, which is the century of the rejuvenation of our Chinese nation. We are college students who grew up in this great era. Fortunately, we are an infinitely happy and enviable generation, and we are also a generation with great responsibilities and arduous tasks. The 16th National Congress of the Communist Party of China pointed out: "In the first two decades of this century, we should concentrate on building a well-off society at a higher level in an all-round way, benefiting more than one billion people, so as to make the economy more developed, democracy more sound, science and education more advanced, culture more prosperous, society more harmonious and people's lives more affluent." The Fourth Plenary Session of the 16th CPC Central Committee put forward a new proposition of building a "socialist harmonious society", and put building a harmonious society in a prominent position alongside economic construction, political construction and cultural construction as one of the main tasks of our party's ruling ability construction. Therefore, the goal of building a well-off society in an all-round way and building a harmonious socialist society is the center and theme of Socialism with Chinese characteristics's overall construction strategy in the 2 1 century, and it is also the unshirkable historical responsibility entrusted to contemporary college students by the times. In today's world, peace and development are the themes of the times, world diversification and economic globalization are two historical trends, and the new scientific and technological revolution represented by information technology is developing rapidly. The external environment with peace as the mainstream, the fierce competition in the process of world multipolarization and economic globalization, and the wave of new scientific and technological revolution make China face enormous opportunities and unprecedented challenges. Only by firmly grasping opportunities and calmly responding to challenges can China achieve economic development, catch up with advanced countries and stand on its own feet among the nations of the world in the new century. 1, understand the basic national conditions of China. China's basic national condition is that it has been in the primary stage of socialism for a long time. Since the Third Middle School of the Eleventh Central Committee, China's socialist modernization has made great achievements. 2.3.2 1 severe challenges facing China in the 21st century. Therefore, we contemporary college students must have a deep understanding of China's basic national conditions, historical opportunities and severe challenges, as well as its own shortcomings and backwardness, so as to catch up and realistically exercise our historical mission. As contemporary college students in the new century, if they want to do something, they must take the historical mission of the times as their own responsibility, grasp the pulse of the times, keep up with the source of development, meet the challenge of change, and thus establish their lofty aspirations to contribute to the development of the times and human progress. 1, the sacred mission is to realize the great rejuvenation of the Chinese nation. The Chinese nation has a long history and has long been at the forefront of human civilization. However, in the tide of modern civilization, China gradually fell behind the times and even became a backward thug. Countless women in China, including China * * * Production Party, have made unremitting efforts to save the nation from peril. 2. It is a historical task to promote a well-off society in an all-round way and build a harmonious socialist society. Building a well-off society in an all-round way and building a harmonious society are two concrete manifestations of China's socialist modernization. This is also an unshirkable historical responsibility entrusted to contemporary college students by the times. 3. The basic requirement is to improve the comprehensive quality of college students. Only by improving their comprehensive quality can we adapt to the requirements of the rapid development and changes of the times and shoulder the historical mission and social responsibility entrusted by the times.

In the journey of life struggle in the future, we should adhere to the unity of studying science and culture and strengthening ideological cultivation, studying book knowledge and joining social practice, realizing the unity of our own values and serving the people of the motherland, establishing the unity of lofty ideals and hard struggle, earnestly studying skills in a down-to-earth manner, practicing basic skills and mastering new knowledge, and making ourselves a person with lofty ideals, loving the motherland, pursuing truth, being brave in innovation, having both ability and political integrity, developing in an all-round way, with a broad vision and a broad mind.
