People are like a seed, to be a good seed. Artemisinin is a gift of traditional Chinese medicine to the world. Foreigners can do it, but Chinese people cannot do it. A group of posters with scientists as the theme are filled with heartfelt words, which is a powerful demonstration of scientists' determination and career, and a vivid epitome of China's scientific development. Today, on the occasion of National Science and Technology Workers' Day, we extend our greatest respect to the national science and technology workers. The time pointer was moved back to May 30th, 2016. The National Conference on Science and Technology Innovation, the Conference of Academicians of the Chinese Academy of Sciences and the Ninth National Congress of the Chinese Association for Science and Technology were grandly held, sounding the horn of building a world science and technology powerhouse. With the approval of the State Council, May 30th of each year will be established as the "National Day of Science and Technology Workers". This year is the seventh National Day of Science and Technology Workers, with the theme of "Lighting the Torch of Spirit". The aim is to vigorously promote the spirit of scientists, unite and guide the majority of science and technology workers to cultivate a strong sense of patriotism, be brave in innovation, and strive to be the vanguard of high-level scientific and technological self-reliance and self-improvement, gathering the inexhaustible driving force for development and rejuvenation. A person without spirit cannot stand, and a country without spirit cannot be strong. Scientific achievements cannot be separated from spiritual support, and the spirit of scientists is a valuable spiritual wealth accumulated by scientific and technological workers in long-term scientific practice. Throughout history, from self-reliance to independent innovation, and then to self-reliance and self-improvement, countless scientific and technological workers have climbed and made breakthroughs under the deployment and planning of the Party Central Committee at each critical historical period, achieving breakthroughs in the field of science and technology and writing a magnificent spiritual chapter. To pay tribute to every technology worker in all walks of life is to salute and light up every beam of light in our hearts. This beam of "patriotic" light illuminates the foundation of scientific and technological workers. Science knows no borders, scientists have their homeland. In 1955, Qian Xuesen abandoned the status, reputation and life of the United States, broke through many difficulties and returned to the motherland. He said that "the purpose of living is to serve the people"; In 2009, Huang Danian, the "Son of the Earth", upheld the ideal of serving the country through science and technology, gave up the advantageous conditions abroad, returned to the motherland, forged sharp tools for the country, opened the "Earth Gate", and firmly believed that "my country needs me more"... Time has passed, and what remains unchanged is the patriotism and ambition of scientists to serve the country. Regardless of the past, present, or future, the development of China's science and technology industry always requires generations of scientists who are dedicated to serving the country to continue their efforts and continue to strive. This beam of "innovation" light illuminates the foundation of scientific and technological workers' career. Scientific exploration never ends, and innovation is always a near death. This is an inherent requirement of scientific research work and a spiritual trait of scientific and technological workers. "Two bombs and one satellite", "China's heavenly eye", manned spaceflight, quantum computer... all these remarkable scientific and technological achievements have emerged from scratch, reflecting China's strong innovation strength and the innovative heritage of the vast number of scientific and technological workers. In the past, our scientists dared to lead the world and gained confidence and confidence in innovation; Today, we must bravely venture into the "unmanned zone", fundamentally change the situation where key core technologies in our country are subject to human control, and cultivate the belief and courage of self-reliance and self-improvement. This beam of "dedication" illuminates the moral character of scientific and technological workers. Science is a persistent cause, and scientific and technological workers also need to remain indifferent and have clear aspirations
