This article 3436 words read for 7 minutes When I was young, I didn't like to memorize words, and I always didn't have enough homework. During the War of Resistance Against Japanese Aggression, he spent his middle school years, and he went to school on an empty stomach when he saw Japanese planes blow up the crater on the campus. In the second year after the end of the Anti-Japanese War, Yang Shi'e was admitted to the Department of Physics of Tsinghua University. In the poor era, he and his roommates shared the money for books and studied for eight or nine hours a day. Before graduating, just in time for the country to establish the navy, Yang Shi'e joined the army and came to Dalian No. 1 Naval Academy to teach, and he became attached to the sea since then.
In the 1960s, he returned from his studies in the Soviet Union and began to prepare China's first underwater acoustic major, teaching students and cultivating teachers. He became an expert in mechanical and transportation engineering and one of the main pioneers of China's underwater acoustic technology. In 1995, Yang Shi'e was elected as an academician of the Chinese Academy of Engineering.
Today, Yang Shi'e, known as the "post-90s" academician, has retired, but he still insists on teaching graduate students. Talking about his college years, 90-year-old Yang Shi'e said, "I'm just an ordinary seed, but when I met some good teachers and good classmates in college, it was like finding fertile soil."
Talking about studying: Going to school on an empty stomach, the campus was bombed out
Beijing News: When did you start school?
Yang Shi'e: In 1936, I was 5 years old and started primary school. After the outbreak of the Anti-Japanese War in 1937, I followed my parents to and fro I went to Henan and Chongqing. I was admitted to Chongqing Nankai Middle School in the first year of junior high school, and went on to the second year of high school. In my third year of high school, I transferred to the Middle School Affiliated to Nanjing National Central University (now the Middle School Affiliated to Nanjing Normal University).
Beijing News: During the war, Do your parents support your studies?
Yang Shi'e: My father is a student at the Tsinghua Preparatory School for Studying in the United States. He asks the five children in the family to study hard and try their best to provide us with a better school. We were frugal, raised chickens and grew vegetables, but my father never let us go to school. During the summer vacation, our parents hired a Malaysian student to teach us English.
Beijing News: How are your grades? About one-third. I am more playful. Sometimes I don’t read serious books, I just read novels and literary history. Nankai Middle School is a male and female branch, surrounded by little boys, wrestling and fighting all day long. I am not in good health. I was too young to beat others. In my senior year of high school, I still loved to go boating on Xuanwu Lake in Nanjing.
The Beijing News: What was the school environment like at that time? There are three two-story dormitories, each floor is divided into small rooms by half-height walls, and one room lives 4 people.
The food is very poor, and the stomach is always hungry. The daily dishes are boiled broad beans, peas or macaroni in salt water Vegetables, no meat, no oil, and occasionally a bowl of tofu is very good.
When eating, you have to grab it. There is a trick that the first bowl should not be too full, otherwise, if you eat slowly, you will not be able to fill the second bowl. .We didn’t have the money to buy snacks, so we could only wait for the weekend to go home to eat some shredded pork, and then use a jar to bring some “private dishes” back to school. Eight people sat at a table and everyone ate together.
Beijing News: Did the war affect campus life?
Yang Shi'e: When I was studying in Chongqing, our school was bombed, and there was a bomb crater on the campus. When school started after the summer vacation, we discovered this pit. It was one meter deep and two or three meters in radius. I even picked out bomb skins from the pit and played with it.
When I was at home on vacation, I once saw a Japanese plane flying over and throwing bombs overhead. We have an air-raid shelter in our house, and someone will hide in it. Our children do not understand the concept of war, nor do we feel afraid, we just watch from the outside.
Talking about the college entrance examination: College entrance examination is not the only way out
The Beijing News: How did you take the college entrance examination?
Yang Shi'e: I took the university entrance exam in 1947. At the beginning of July, I applied for Shanghai Jiaotong University, and later I went to the then National Central University and Tsinghua University. They are all taken in the summer, and there are ten days between each exam.
Beijing News: What is the exam process like?
Yang Shi'e: At that time, Tsinghua University rented an empty house in Nanjing as an examination room, and took Chinese, mathematics, English, physics and chemistry. We took the test for two days, one person per seat, and we used pencils and pens to answer the questions. The test format was similar to the current college entrance examination.
Finally, I was admitted to the Department of Physics of Tsinghua University, and I expected this result after finishing the test paper. Tsinghua published the admission list in the newspaper and gave the admission notice.
Beijing News: Is it difficult for Tsinghua University to test?
Yang Shi'e: In fact, it's okay, not necessarily difficult to test. Because there are many opportunities for exams, I didn't feel nervous, I studied like normal, and I didn't prepare specially.
Beijing News: What do you think of the college entrance examination?
Yang Shi'e: Studying is always useful, but going to university is not the only way out.It's good to pass the test, but if you don't pass the test, it's not necessarily worthless. You should treat it with a normal heart.
There are three things to learn when going to college, being a person, doing things, and finally learning knowledge. Later, when I was a professor, I always told my students that no matter how famous a professor is, they can’t teach you new technologies and knowledge 10 or 20 years later. It depends on your own will to learn and innovation.

Talking about university: I pooled money to buy books with my roommates. Three of the four people in the dormitory are academicians.
Beijing News: What did you prepare when you went to the university to report?
Yang Shi'e: I took a day boat from Shanghai to Tianjin, and then took the train to Beijing. The luggage is very simple, a bedding roll, a box, some books and a change of clothes in it.
Beijing News: What is a university classroom like?
Yang Shi'e: Our school implements a course selection system, and you can choose any course you want to take. The relationship between students and teachers is relatively natural. We like to go to the teacher's house after class, sometimes to discuss problems, sometimes just to visit. What impressed me most about
is that some teachers not only teach you knowledge, but also teach methods, which has a great influence on me.
Beijing News: Did your university studies go well?
Yang Shi'e: It's just over a month since I took the mid-term exam. The questions are very difficult and they are all topics that I haven't learned before. I got 50 points on the test and failed. There was a saying at the time that if two-thirds of the students in the class failed, the exam would be considered a success, meaning that it would give the students a slap in the face.
The Physics Department of Tsinghua University has a characteristic that it does not admit you as a physics student in the first year. After the first grade is completed, the subjects of general physics and advanced mathematics are allowed to enter the department with a score of 75 or more. When we entered the department, there were more than fifty people in the department, and by the second grade, there were more than thirty left.
Beijing News: What impressive experiences did you have during college?
Yang Shi'e: The dormitory I live in is a dormitory for academic masters. Among the four roommates, Zhou Guangzhao, Gao Bolong and I were elected academicians later.
At that time, some college students were very old, and some had children. At that time, everyone had no money, and they wanted to buy books. My roommate Zhou Guangzhao and I bought them together, and each person paid half of the money. At that time, there was nothing to choose from in food and clothing, and I was willing to spend money only on books.
During college, in addition to studying, I also learned to play the piano, participated in the singing team, and taught children literacy in the countryside around the school in my spare time.
Beijing News: College students at that time were very enthusiastic about learning?
Yang Shi'e: At that time, our class counted everyone's study time. People who love to play like me often read in the library and study for about 60 hours a week. Zhou Guangzhao is such a hard worker that he spends more than 75 hours of study a week, more than ten hours a day.
I am not the most powerful among my classmates. My roommate Gao Bolong always scolds me for being "playful" and grabs me by the back of the neck and takes me to the library. After thinking about it, if I hadn't met these good teachers and good classmates at the university, I would have run away.

Talking about work: At the age of 88, you are still experimenting overseas. You must use your residual heat as much as possible.
Beijing News: Where did you go to work after graduation?
Yang Shi'e: In the early 1950s, the country was catching up with the establishment of a navy. Dalian Overseas School dispatched young teachers and senior students to Beijing as teachers. At that time, I was in my fourth year of college, and before I finished my studies, I joined the army with a few other classmates. Before I left, I even shared with my roommate Zhou Guangzhao the dozens of books we bought together.
In 1952, I went to Harbin Military Engineering (Harbin Military Engineering College, now Harbin Engineering University) as a teacher.
In 1957, he went to the Institute of Acoustics of the Soviet Academy of Sciences for further studies. There are four research laboratories there, two of which are closed to the Chinese, one for ship noise and one for sonar, all of which involve national defense secrets. I knew then that I had to do this on my own.
In 1959, I returned to China, and at the end of the year, I officially participated in the South China Sea inspection as the vice-captain of the Chinese side. In 1960, I was preparing to establish a major in underwater acoustics in Harbin Military Industry, which was the first and is the only relatively complete major in underwater acoustics in China.
Beijing News: Have you ever experienced a tough time?
Yang Shi'e: Actually, everything is fine. In 1994, I was leading a hydroacoustic survey in the South China Sea. It was hot and seasick. I sing to encourage everyone and soothe the emotions of the team members. When I was in the Nansha Islands, there was no drinking water. There was fresh water in the ballast tank at the bottom of the ship, but there was a layer of diesel oil floating on it.
Beijing News: You later became a university teacher, what educational experience do you have?
Yang Shi'e: I later became a teacher at Harbin Engineering University. I liked to ask questions in class, but few students answered them. No students disagreed whether I was right or wrong. Occasionally speaking, I will quickly praise him, no matter what he says, encourage him first.
I like to ask questions, to inspire rather than indoctrinate students. I always say that I am just an ordinary seed, but I met some good teachers and good classmates during my school days. It was like finding fertile soil, so the seedlings grew.
Beijing News: Are you still working after retirement?
Yang Shi'e: I retired at the age of 88 in 2019, but that year I was still experimenting overseas. For me, there is no difference between retiring and not retiring. Some things have to continue.
I was still teaching graduate students last month.As I said before, although people are retired, the work that contributes to the motherland should not be retired. It is necessary to make use of the residual heat as much as possible, so that even after the sunset has fallen on the Cangshan Mountains, the sunset glow is still full of red.
