From unmanned flight to manned flight, from one person per day to more than one person per day, from in-flight experiments to extravehicular activities, from single ship flight to stable operation of the assembly... For China's manned space program, which has just entered its thirties, a series of remarkable achievements cannot be separated from the hard work of a group of ambitious young people with lofty aspirations, creativity and sense of responsibility. In the past decade, we have overcome many problems that have not been solved for a long time. We have accomplished many important things that matter for a long time. The cause of the Party and the country has made historic achievements and undergone historic changes. Under the guidance of the Party's innovative theory, Chinese youth in the new era bravely shoulder heavy burdens, fight risks and overcome difficulties, so as to make the cause of socialism with Chinese characteristics in the new era full of vitality, stamina and hope. It is a relay race to build a powerful socialist modernization country and realize the great rejuvenation of the Chinese nation. In 1954, China's first youth commando was founded by 18 youth league members in Beijing. Over the past 60 years, under the strong leadership of the Party, the famous name of "youth commandos" has moved from hot construction sites to all walks of life. Groups of young commandos have been active in various battlefields of socialist modernization. With the heroic passion of "there are youth commandos in front of difficulties, and there are no difficulties in front of youth commandos", they have demonstrated the youth's boldness, courage, determination and responsibility in the face of "urgent, difficult, dangerous, heavy, new" and other tasks, It has played a vital role in economic and social reform, development and stability. Facts have proved that Chinese youth in the new era are not afraid of difficulties and hardships. They show their spirit in the midst of danger. They can always stand up and shoulder their responsibilities when the motherland and people need them. They are active in production and operation, engineering construction, scientific and technological innovation, emergency rescue and relief, emergency security, safe production, social services and other fields. They shoulder mountains of responsibility with their tender arms, write a passionate style with their brilliant youth, and show the enthusiasm of young people who are more difficult and forward. On the new journey, in the face of more obvious changes in the world, times and history, it is urgent for Chinese youth in the new era to work hard to create a better China with youth wisdom and sweat. To continue the struggle, we must step out of the "comfort zone" and dare to face difficulties and overcome difficulties. He who wins is strong, and he who is strong wins. Comrade Mao Zedong once said, "What is work, work is struggle. Those places have difficulties and problems, which need us to solve. We work and struggle to solve difficulties. The more difficult the place, the more we want to go, and this is a good comrade." Without the continuous hard work of generations of young people, there will be no today in the new era of socialism with Chinese characteristics, and no tomorrow to achieve the great rejuvenation of the Chinese nation. For young friends struggling on all fronts of the socialist modernization drive, we should grasp and adapt to the new process of deepening reform, respond to the new needs and expectations of the people, inherit the good tradition of Chinese youth's permanent struggle, and dare to face difficulties in the face of conflicts
