Early learning stage
On May 21, 1903, Chen Guangxi was born in Tongcheng County, Anhui Province. His father was a former Qing Dynasty.

In May 1920, Chen Guangxi began a voyage to work and study in France.

Chen Guangxi spent a whole 10 years of hard work in France and Belgium. While working as a fitter, he studied geosciences at the university and obtained five professional degrees and agricultural mechanics, three engineering engineers, civil engineering and mining engineers and geotechnical engineers.

In 1922, he graduated with honors from the University of Lusit University in agricultural machinery with a year of excellence and obtained a degree in agricultural mechanics. In 1929, he graduated from the Engineering School of the University of Leuven, Belgium with a degree in Process Manufacturing, Civil Engineering and Mining Engineering. In 1930 he graduated from the Graduate School of Geology and obtained a degree in geology engineering.

During his studies in France, Chen Guangxi's diligent study spirit and outstanding achievements were praised by teachers and alumni. Someone advised him to stay in France as an engineer, but he refused. He misses the distant motherland day and night, and he must contribute his knowledge to the science and technology cause of the motherland. However, in October 1930, when he returned to the lovely motherland, he was greeted by a smoke-filled, devastated river.

In the 1930s and 1940s, it was the era of rapid social turmoil. After spending more than a year, he finally found a place to teach and began to teach mathematics in a middle school. Although learning is not used, it is very distressing, but in order to survive, in order to support the family, Chen Guangxi can only accept the reality reluctantly and teach with peace of mind. Later, he successively worked as a lecturer at Shanghai University of Labor, a course translation in the Northeast Navy in Qingdao, a physical and chemical teacher in the first teacher of Kaifeng, Henan, and a math teacher in the middle school of Beijing Furen University. In September 1933, he was hired as a lecturer in the Department of Mathematics and Physics at Beijing Furen University. In September 1938, he was promoted to a professor by Fu Jen University.

In 1945, the end of the Second World War, the Chinese people's war of resistance against Japan won a great victory. The Ministry of Education of the National Government added the National Peking Senior Industrial Vocational School and appointed Chen Guangxi as the principal. On October 2, 1946, Chen Guangxi was reported to the Ministry of Education to "take the inauguration and activate the slogan."

On October 1, 1949, the establishment of New China opened a new page in Chinese history. It was a shining road in front of Chen Guangxi. After many years of hard work and expectation, I have finally got a new starting point. Chen Guangxi’s patriotism and his desire to serve the country have finally come true. He went to a design institute in the Ministry of Machinery Industry as the chief engineer. Professor Chen, who is already in his 50s, still feels like a vibrant youth. He looks at the development of science and technology in the world. When a group of electronic computers were first introduced in foreign countries in the early 1950s, Professor Chen Guangxi was sensitive to science and found that this was a new life with infinite vitality.

In 1957, Li Chang, the president of Harbin Institute of Technology, sent a group of old professors to Beijing to start a new major. For the scientific career of the motherland, Professor Chen Guangxi gave up Beijing's superior working conditions and comfortable living environment without hesitation. He left the technical leadership position that was already high for him, and took the family to go to the North China Ice City with his own courage. —Heilongjiang Harbin, in the thousands of miles of ice, thousands of miles of snow outside the North of Xinjiang, rooted in the Harbin Institute of Technology to create a new computer science.

Outstanding achievement
From the birth of the world's first electronic computer, the level of computer science and technology, the scale of production and the degree of application have become a symbol of the level of modernization of a country. It will promote profound changes in science and technology and have a profound impact on social production and social life. Chen Guangxi deeply understands this point and always grasps the direction of research with profound knowledge. The subject he has chosen has always been at the forefront of computer science. Because it is the frontier, it is a new field that others have not tried. Therefore, in front of Chen Guangxi, it is also difficult to focus on.

In 1958, during the National Education Revolution, the computer major students of Harbin Institute of Technology who were educated in traditional research were encouraged by the young people to dare to do so under the encouragement of the National 12-year Scientific Development Plan and the march to science. The spirit of posting a large-character poster "will be the teacher's army." They put forward: "What kind of gift do we offer to the National Day? We also have to do computers!"

Hard work pays off, under the leadership of Chen Guangxi, through the hard work of everyone's concerted efforts, in 1958, the first computer in New China that can speak and play chess was born at Harbin Institute of Technology. This intelligent chess computer can calculate 40,000 times per second, with logical reasoning ability, can complete specific tasks of judgment and thinking.

In 1963, Professor Chen Guangxi presided over the development of ultra-small magnetic cores, laying the foundation for the development of millions of computers. Later, under the guidance of Chen Guangxi, the teaching and research section carried out a magnetic core molding process experiment of “rolling into a belt and rubbering into a core” and achieved success. This core forming technology of “rolling into a belt and punching into a core” is an advanced technology with original innovation, which was quickly promoted in China and supported the high speed of China in 1967-1980 for more than 10 years. The development of large-capacity memory and the production of transistor computers and early small-scale integrated circuit computers is a major contribution made by computer science to the development of computer technology in China.

In 1973, Chen Guangxi, 70 years old, proposed a major research project to solve the problem of computer stability and reliability, and an innovative research direction - computer fault tolerance technology. Due to the significance of this project research, it was quickly approved as a “national project”. At that time, the National Defense Science and Technology Commission attached great importance to the allocation of 1 million research funds, equivalent to one billion now. Although the fault-tolerant computing technology was not used at the time, Chen Guangxi said: "Now it is not useful, but it will be useful in the future."

Under the leadership of Chen Guangxi, after the full discussion and argumentation of all the comrades in the development team, the overall plan was finally determined as “a dual-mode fault-tolerant system with self-test and self-correction”. He and the comrades of the development team fought day and night. In 1979, he successfully developed China's first fault-tolerant computer "RCJ-1", which was praised as the pioneer of fault-tolerant computer research in China, and its reliability increased by more than four times. Chen Guangxi also co-published the first fault-tolerant computing monograph "Diagnosis and Fault Tolerance of Digital Systems" in cooperation with Professor Chen Tingyu of Chongqing University. In 1981, it was published by the National Defense Industry Press and became a national textbook.

Under the leadership of Chen Guangxi, Harbin Institute of Technology's computer fault-tolerant research has achieved many impressive achievements, and has established a high prestige in China's aerospace field, banks and high-reliability computing. The fault-tolerant technology of the Shenzhou series spacecraft return cabin is also provided by Harbin Institute of Technology.

Since then, Chen Guangxi has also guided research projects such as “enforcement hardening” and “database machine”, and have achieved significant scientific and technological achievements, and won many first and second prizes for national scientific and technological progress. The discipline was approved by the first batch of doctors, key disciplines, key laboratories, postdoctoral mobile stations, etc., and gained advanced status in the same discipline in China.

In May 1978, Chen Guangxi was appointed as the vice president of Harbin Institute of Technology. However, he never regards himself as a predecessor or leader, he still regards himself as a "stepping stone." He said that he is a "stepping stone" for computer teachers and a "stepping stone" for students. He often said: "I am serving you."

Later generation evaluation
Chen Guangxi is an old intellectual who came from the old society and personally experienced the establishment of the Manchu government, the Revolution of 1911, the warlords, the Kuomintang rule and the founding of New China. The contrast between the old and new society made him believe that only the Chinese Communist Party can save China. "In the past, in the society, the slogan of 'Science Saving the Country' and 'Educating the Country to Save the Country' was put forward, and many aspiring young people struggled for it. But in the old China, there is no scientific or educational status, so what about saving the country? Now it seems that science depends on science. Education can't save the country. Only revolution and science education can save China. Only socialism can save China!" Looking back, Chen Guangxi has been filled with emotions. He firmly believes that in China, apart from the Communist Party, no one can solve China's problems; only socialism is China's only way out. He is determined to integrate his lifelong pursuits and his entire life into the magnificent communist cause.

Although he has been in the prison of the Communist Party twice in his life, he is still very yearning for the party. He entered the prison during the "three anti-" period in the 1950s, and was labeled as a special agent in prison during the "Cultural Revolution." However, he did not have a bit of resentment. When someone asks him: "How do you think about this?" He said: "The Communist Party is like a mother to a child. Mothers love children, sometimes they fight children, sometimes they are reasonable, sometimes they don't care. Mothers mistyped children. Can children avenge their hatred?” In a few words, Chen Guangxi’s infinite love and affection for the party was also revealed. He also expressed the noble feelings of an old intellectual who “had a heartless selflessness”. He uses a heartless, fearless, unrestrained, dust-free heart, with a more broad mind than the ocean and the sky.

On December 6, 1991, in the conference room of the Harbin Institute of Technology Computing Center, the 88-year-old Professor Chen Guangxi read the application for joining the party with great excitement and expressed his firm confidence in communism. The party branch meeting unanimously agreed to accept him as a probationary member of the Chinese Communist Party.

On June 20, 1992, Professor Chen Guangxi finished the 89 Spring and Autumn Periods of his life and ended his life journey. His body is covered with a party flag and lies peacefully in the flowers. His disciple and Li Mingshu, the post of director of the Software Research Institute of the Chinese Academy of Sciences, made a "Mulberry Seed" at the time, and he screamed at the teacher: "The West Wind throws away the tears of the Qiang, and hurts the teacher. It hurts to be a teacher, but now the life and death of the future. After the inheritance of Qianqiuye, you please rest in peace. Please rest in peace, and he will renew his report."

To commemorate the glorious life of Mr. Chen Guangxi, on June 5, 2005, on the occasion of the 85th anniversary of the founding of Harbin Institute of Technology, the bronze statue of Mr. Chen Guangxi, proposed by Professor Li Sheng and inscribed by the old principal Li Chang, was unveiled at the comprehensive building of the School of Computer Science. Computer science alumni and computer school leaders, teachers, students and family members of Mr. Chen Guangxi have attended the unveiling ceremony. Everyone has a deep and sincere review of Chen Guangxi's outstanding contribution to the development of the computer industry and the development of the computer industry in China for more than 40 years.
