China's Father of Microwave Refuses to Serve the Motherland with High Salaries

- May 08, 2019 -

Henan Microwave Equipment Network News: In the academician building of Chengdu University of Electronic Science and Technology, a spiritual old man quietly leaned on the bookcase, reading newspapers, reading books and writing dense formulas with a magnifying glass. He is Lin Weigan academician, father of China's microwave. Although he is 90 years old, he still works hard and persists in learning until 10 p.m. every day for decades. "To be a graduate student for a lifetime" is Mr. Lin's wish. Lin Weigan was born in Taishan County, Guangdong Province, in 1919. Father Lin is a lawyer who has read four books and five classics. Influenced by his father, the young Lin was diligent and eager to learn, and he was excellent both in character and learning. In 1935, Lin Weigan, who was only 15 years old, was admitted to the Department of Electrical Engineering of Tsinghua University as "the champion of his hometown". Four years later, he graduated from undergraduate course and became a telephone technician. During the Anti-Japanese War, Lin built and repaired telephone lines on the front line of Baoshan, Yunnan Province, to ensure wartime communications. In 1943, Lin Weigan, 24, met Deng Rongfen, a Jiangsu girl who worked as an accountant in Kunming Post and Telecommunications Bureau. They often played basketball and volleyball together, and soon came together. One year after marriage, his son Lin Heyu was born. In 1945, the War of Resistance Against Japan won, and Lin Weigan got the chance to study abroad. In September of that year, with the double joy of victory and studying abroad, Lin Weigan said goodbye to his wife and children and embarked on a journey to the United States. From the smoky battlefield to the beautiful and quiet campus, Lin Weigan cherishes the opportunity to study at Carolina State University. After one semester, all his grades are A. A year later, Lin Weigan successfully entered the University of California, Berkeley. After Lin went abroad, his wife Deng Rongfen left Yunnan with her children and went to Chongqing Post and Telecommunications Institute to work. Then she traveled to Nanjing and Guangzhou. After the founding of New China in 1949, a large number of foreign students, scholars and scientists, such as Hua Luogeng and Li Siguang, broke through the obstacles and returned to their motherland. In 1950, after the defence of his doctoral dissertation was passed, Lin Weigan posted his paper "One-Space Multimode Microwave Filter" to the Journal of Applied Physics of the United States. Later, the paper was published on the front page of the Journal of Applied Physics in August 1951. In March 1951, after receiving his Ph.D. from the University of California, Lin Weigan began to prepare for his return home: first, he sold his own home, sold his car, returned his rented house, and then handed over his job. About 11 overseas students returned home when the time was ripe. The U.S. authorities tried to keep them at a high salary and were flatly rejected.

Seeking help from the motherland at sea

Ergorin is the main motive force for Lin Weigan to decide to return home. "My second brother has the greatest impact on my life." Mr. Lin recalled that in 1943, Lin Weiliang was killed by warlords in Xinjiang along with Chen Tanqiu and Mao Zemin. He remembered the revolutionary martyr who died at the age of 27 all his life. "I promised my second brother that he would come back to build a new China."

In August 1951, Lin started his journey from the United States. First, he left the West Coast of the United States without releasing people. When the ship was about to arrive in Hong Kong, they were informed that they could not land in Hong Kong and would be returned to the original ship. "Already near the door of the motherland, where is the reason to go back?" Lin Weigan immediately called everyone to discuss countermeasures, decided to try to use the ship's radio to send a distress signal to the Education Department of Guangdong Province. After two days'drifting on the high seas, the other party called back and said that they would send boats to meet them on the high seas. Upon receiving the news, 11 overseas students shouted, "Long live the motherland!" A few days later, Lin Weigan and other students landed in Guangzhou. At this time, in a humble residence near Guangzhou Post and Telecommunications Bureau, his wife, Deng Rongfen, was at home, studying for his 7-year-old son in dim light. When the knock came, Lin Heyu jumped down from the stool and, like a telepathic voice, shouted "Dad" and went to open the door. Outside the door, Lin Weigan, dressed in a suit, put down his suitcase and picked up his son. After returning to China, Lin Weigan taught at Lingnan University and South China Institute of Technology. In 1955, Chengdu Telecommunication Engineering College was formally approved by the State Council, and Lin Weigan became the first "senior" professor in the school. In the spring of 1958, Lin Weigan spent a special Spring Festival on the train with his wife and children and later arrived in Chengdu. During the Cultural Revolution, Lin Weigan went to the teaching and research room every day as usual to study electromagnetic wave technology. Later, he was criticized and thrown into the Labor Reform Team to do miscellaneous work and dredge sewers. At that time, he still did not forget scientific research, quietly took out academic works hidden under the quilt every night, and studied with the help of dim light. In the eyes of Zhu Jianhua, the wife of Lin Lao now, Lin Weigan "has no shelf, does not pay attention to it, is busy with work and will live soon". The leather shoes on his feet are worn until they are broken; a belt has been broken into two pieces for more than 40 years, so he can find a shoemaker to take over and continue to use it. Reporters see that Mr. Lin's desk has many newspaper clippings, notes, straw paper, and even the newspaper seams, corners are full of formulas. "To be a graduate student for a lifetime" is Mr. Lin's wish. The students call Mr. Lin Lao a "lifelong scholar".

P>P>_Academician's Family Affairs

Continuing to train nannies to learn English

1985, his wife Deng Rongfen became seriously ill and died suddenly. With 43 years of dependence, the loneliness of the couple in old age has hit Lin Weigan heavily. At this time, Zhu Jianhua, a hard-working woman from rural Sichuan, who works as a housekeeper in the Linjia family, entered the life of Lin Wei. Four years later, Lin Weigan put forward the idea of living together. "How can a rural woman deserve a university professor?" Zhu Jianhua hesitated because of the disparity of status and knowledge level. < P > < P > Lin Weigan consoled Zhu Jianhua. As long as he devoted himself to learning, there would be no gap. Afterwards, Lin Weigan taught Zhu Jianhua, who had only primary school culture, to learn English, supervised and supported her: every morning at 6:30, Zhu Jianhua listened to English radio; her pronunciation was not standard, Lin Weigan asked a student to teach her international phonetic symbols; Lin Weigan also bought a special tape recorder to record her pronunciation, one by one to correct... Until Zhu Jianhua got his junior college diploma.

In March 1991, Lin Weigan and Zhu Jianhua held a simple wedding ceremony. Now, Zhu Jianhua is an archivist at the University of Electronic Science.

If the teacher does not read, he will not recognize him

in the "Cultural Revolution" was involved, and his son Lin Heyu was sent to Dazhu Telecom Bureau at the foot of Daba Mountain to repair the mobile phone. Lin Weigan often wrote letters to his son, warning him that even if he worked hard, "you must read and read carefully". He even threatened to say, "If you don't study hard, I won't recognize your son because I have many students."

In 1980, his son, Lin Heyu, went to Canada to study radio electronic engineering and obtained a doctorate degree from Manitoba University. During this period, Lin Weigan also went to the school to give lectures, and stayed with his children and grandchildren for more than three months. Lin was so devoted to scientific research that the family rarely reunited, which was the longest time their father and son had spent together.
