Nowadays, fewer and fewer young people know the name Li Pei.
The old man and Li Zhengdao helped the first batch of self-funded students in China to go abroad. At that time, there was no TOEFL and GRE test, so she wrote her own questions, and Lee Zhengdao selected students in the United States.
At the age of 81, she founded the Zhongguancun Grand Forum, which ran more than 600 sessions from 1998 to 2011. The keynote speakers she invited were also "famous horns" in various fields, and Huang Zuqia, Yang Le, Zi Zhongjun, Li Yining, Rao Yi, and other famous artists had all appeared on this big forum.
Her only daughter, Guo Qin, died of illness. No one saw her shed tears when she was nearly eighty years old. A few days later, as usual, she took the tape recorder and gave English lessons to the doctoral students of the Graduate School of the Chinese Academy of Sciences.
Entering the 99th year of his life, Li Pei's brain's "memory is getting smaller and smaller", and the memory is not as good as before. She pays the nanny 3 times a month; She said that the current TV show is too ugly, "Where have the people of the Republic of China gone?" ”
In her small living room, the gray cloth sofa with some crooked legs has endured the various sizes of various large figures of different ages in 60 years. Qian Xuesen, Qian Sanqiang, Zhou Peiyuan, Bai Chunli, Zhu Qingshi, Rao Yi, Shi Yigong... They were all guests of that couch.
But sometimes more people come, and no matter how big the officials are, they all have to sit on the pony.
She had traveled half the world, and now her back was hunched like a folding ruler, curled up on the couch in the south-facing study for most of the day, snuggled up on the electric heater when she was sleepy, and even though it was three days, she felt cold. A few years ago, when she saw the young man riding a bicycle and hitting the old scientist in Zhongguancun, she was particularly angry and chased after her. Now, she didn't even have the strength to stand on the balcony and wave to her friends.
Only teeth and stomach, still working tenaciously. Her stomach had been filled with Hu Shi's meat dishes, Lin Jiaqiao's dumplings, and Qian Xuesen's Western food, and at that time, Zhou Peiyuan, who had poor cooking skills, only had to wash dishes. Today, she loves garlic bread like she did when she was young in the United States, grinding it slowly with her teeth.
Her eyebrows were getting lower and lower, and her wrinkled eyes had seen the braids of the late Qing Dynasty and the early Ming Dynasty, the knives of the Japanese, the skyscrapers of the United States, and the ups and downs of China over the past hundred years. Today, nothing can make this centenarian happy and sad.
She has been an enemy of time all her life. He is in his 70s studying computers, and he is still teaching doctoral students at the age of nearly 80. In her later years, she used more than 10 years to open more than 600 "Zhongguancun Grand Forums" that were earlier and higher-standard than CCTV's "Hundred Forums".
No one can count how many of the old scientists of the Chinese Academy of Sciences are her students. Even in academic circles, bringing her something from Hong Kong, she can receive it by mentioning "Mr. Li Pei of Zhongguancun". The number of her "postmen" and the level is amazing.
At Qian Xuesen's memorial service, there was a specially paved academician passage, and Li Pei, who was wrapped in a long white scarf, was "taken for granted" and "sacrificed to me" on this road, and some people commented that this skinny old lady who weighed only a few dozen pounds was "more academician than academician."
She has been called "the most beautiful rose of the Chinese Academy of Sciences", "the bright light of Zhongguancun", and "the young and old".

1. Life is an eternal heavy effort
The centenarian's residence, like her own, was quite old and long.
Buildings 13, 14 and 15 of the Keyuan community in Zhongguancun are known as the "Special Building", where a group of founders of modern science in New China live: including 9 academicians of the Academia Sinica in 1948, 32 of the first batch of 254 members of the Faculty, and 8 of the 23 winners of the "Two Bombs and One Star" Meritorious Service Medal. Qian Xuesen, Qian Sanqiang, He Zehui, Guo Yonghuai, Zhao Jiuzhang, Gu Zhun, Wang Ganchang, Yang Jiaqi, Pei Shizhang and others all lived here.
Today, the dilapidated "Keyuan Community" sign, the word "Ke" is only the word "Bucket", the corridors of the old building are plastered with small advertisements for "dredging sewers", and the courtyard is piled up with debris. It is no longer "a gathering place for China's brightest minds", but is rented by many migrant workers, knocking on a door and sticking out a head: "Wang Ganchang? Pei Shizhang? Guo Yonghuai? Never heard of it. ”
The house prices in Zhongguancun are almost 100,000 yuan a square meter. Not far away, the large LED screen flashes advertisements for the latest high-tech products.
Mr. Li Pei's home, unchanged for 60 years, is like an isolated island in Zhongguancun.
On this island, there was once the famous Mr. Guo Yonghuai.
Guo Yonghuai and Li Pei and his wife returned from Cornell University in the United States with their daughter, which was invited by Qian Xuesen. Qian Xuesen wrote to Guo Yonghuai several times in 1956: "Please come to work at the Institute of Mechanics of the Chinese Academy of Sciences, we have prepared your 'office' for you in the institute, which is a south-facing room on the second floor, with pale green curtains, and a row of pine trees looking out." "Having 'registered' your name with the Management Office of the Academy of Sciences, it is natural to come to the Institute of Mechanics, come quickly, come quickly!"
After returning to China, Guo Yonghuai served as deputy director of the Institute of Mechanics, and Li Pei did foreign affairs work at the Chinese Academy of Sciences. It wasn't until the day after the first atomic bomb on the mainland was successfully exploded, when Guo Yonghuai and his friends were drinking happily, that Li Pei realized something.
On October 3, 1968, Guo Yonghuai came to the Qinghai Test Base again to prepare for the test of China's first missile thermonuclear weapon. On December 4, after discovering an important clue during the test, he hurried to Lanzhou that night to fly back to Beijing. At about 6 a.m. on the 5th, the plane crashed while landing at the western suburbs airport.
There were more than a dozen people on the plane at the time, and only one survived. He recalled that as the plane began to shake violently, he heard a man shouting, "My briefcase!" "I don't remember what happened afterwards.
Two people in the charred corpses hugged each other tightly, and when people laboriously separated them, they found that between the chests of the two corpses, a confidential briefcase was intact. In the end, it was confirmed that the two people were Guo Yonghuai, 59, and his guard Mou Fangdong.
Guo Yonghuai once taught a turbulence course in a university that few people understood, and Li Pei, who had lost her husband at the time, was experiencing the biggest turbulence in her life.
According to colleagues at the Institute of Mechanics, Li Pei, who learned of the bad news, was extremely calm and hardly said a word. Li Pei was completely awake that night. She lay on the bed barely moving, occasionally letting out a soft sigh, restrained to the point of heartache.
At Guo Yonghuai's memorial service, Li Pei, suspected of being a spy and subject to severe political scrutiny, sat alone on a bench. In the environment at that time, daring to sit next to Li Pei and say a word of comfort required great courage.
Twenty-two days after Guo Yonghuai left, China's first thermonuclear missile test was successful.
At those times, people downstairs often heard Li Pei's daughter Guo Qin playing Li Tiemei's singing section in "Red Lantern" on the piano: "My father is like a pine cypress with a strong will, standing up to the sky..."
Later, Li Pei invited Guo Yonghuai's ashes from the strictly graded Babaoshan Martyrs Cemetery and buried them under the sculpture of Guo Yonghuai in the Institute of Mechanics of the Chinese Academy of Sciences. At the same time, Li Pei also placed part of the ashes of the guard Mou Fangdong, who died with him, under the sculpture.
"Xiao Mu is too young, it's a pity, and it was also for the sake of following him, so he sacrificed." Li Pei said.
Two years after Guo Yonghuai left, her teenage daughter went to Inner Mongolia to go to the countryside as a zhiqing, and Li Pei went to Hefei University of Science and Technology to continue to be examined and reformed through labor. The turbulence of politics has swept them into a whirlpool time and time again.
In the decades since, Mr. Li Pei has hardly mentioned "Lao Guo's death", and no one can say what kind of pain she has endured. It's just that she sometimes stands on the balcony in a daze for hours at a time.
The greater turbulence of life occurred in the 1990s, and her only daughter, Guo Qin, also died of illness. No one saw Mr. Li Pei, who was nearly eighty years old at the time, shed tears. The old man silently collected the blinking dolls that his daughter played with when she was a child. A few days later, as usual, she carried the tape recorder to the Doctoral Students of the Graduate School of the Chinese Academy of Sciences to take An English class, but her voice was hoarse.
Guo Yonghuai and Li Pei accompanied their daughter to play the piano
"Life is an eternal heavy effort." Mr. Yan Jiyi, an old friend of Li Pei and a colleague of the University of Chinese Academy of Sciences, used this famous quote by Milan Kundera to describe Mr. Li Pei.
The last time her daughter Guo Qin saw the writer Bian Dongzi who lived downstairs, she said with a pair of sincere eyes: "Write about my father." Bian Dongzi later wrote "The Story of zhongguancun special building", he said: "Even if she has profound skills, how can she write all, write thoroughly, and write accurately about her great father and equally great mother!" ”
Until September 18, 1999, Li Pei sat in the Great Hall of the People, and the state awarded 23 scientists the "Two Bombs and One Star" Meritorious Medal. Mr. Guo Yonghuai is the only martyr among the 23 "two bombs and one star" founding fathers.
After Li Pei returned home, her daughter Guo Qin's friends all shouted to come to her house to see "that big lump of gold." The medallion is 8 centimeters in diameter, cast in 99.8% pure gold, and weighs 515 grams – everyone sighed, "indeed frighteningly heavy".
Four years later, a friend of Li Peituo's who came to Hefei packed the medal in his friend's suitcase and donated it to the University of Science and Technology of China. When Zhu Qingshi, the principal at the time, opened the box, he was very moved.
2. Donation is donation, what ceremony is required
In Li Pei's eyes, there is nothing that cannot be abandoned.
A few years ago, on an ordinary summer afternoon, Li Pei asked Li Weige, who was in her 30s, to accompany her to the bank and donate 600,000 yuan to the Institute of Mechanics and 300,000 yuan each from the University of Science and Technology of China.
There is no ceremony, as usual as dealing with a bill of water and electricity bills.
"To donate is to donate, what a ritual." The old lady said to Li Weige.
To this day, the coffee table in Mr. Li Pei's living room is still the dowry of the family when he returned to China 60 years ago.
In the early years, I brought back a hand-cranked computer, an electric fan, and a Xiaoice box from the United States and donated it. After Guo Yonghuai left, he donated writing desks, books, and music records. Mr. Li Pei's lifelong teaching of English lesson plan, donated. Wenchuan earthquake, saving Kunqu opera, for the mentally handicapped kindergarten, she donated money.
Some juniors said that she treated fame and fortune like Marie Curie bookmarked the largest pound sterling and gave the Nobel Prize medals to children as toys.
Until the year before, on the day of Guo Yonghuai's 104th birthday, Li Pei took out the collection that had accompanied him for decades and donated them to the Institute of Mechanics: the commemorative seal that Guo Yonghuai used during his lifetime, the exquisite slide rule, the Longines pocket watch, and mr. Guo's relics packaged in an envelope by the Civil Aviation Administration of China's Beijing Administration in 1968 - spectacle lenses and watches blackened by flames.
Today, these things are kept in Room 304 of the Institute of Mechanics, and the dark brown door reads "Guo Yonghuai's Deputy Director's Office." Next door is the "Qian Xuesen Director's Office". Qian Xuesen was right, looking out from the office, it was a row of tall and green pine trees. It's just that half a century has passed.
Time has raised the pine tree, and also given Li Pei a lot of gifts of life.
When the Cultural Revolution ended and she returned to work, she was almost 60 years old. She established the English Department of the Graduate School of the Chinese Academy of Sciences (later renamed the "University of the Chinese Academy of Sciences"), and trained the earliest batch of master's and doctoral students in New China.
At that time, there were no English textbooks for graduate students in China, so she wrote it herself, and every time she took a class, she brought a large volume of mimeographed textbooks and distributed it to students. These textbooks are still in use today.
She reformed English teaching and was called "the mother of applied linguistics in China" by Russel Campbell, chair of the Linguistics Department at UCLA. She boldly asked students to read original English books such as "A Tale of Two Cities" and "Pride and Prejudice". For all graduate thesis defenses, she asked students to make statements in english.
Many students recall that Mr. Li Pei never reprimanded students loudly, but there was a kind of "smile severity", she put the most mischievous students in the first row, this invisible pressure makes people dream of speaking English.
Today, in the eyes of Peng Gong, director of the English Department of the University of the Chinese Academy of Sciences, Mr. Li Pei, who always brings small snacks to his colleagues, is decisive in doing things, which is a kind of "humane decisiveness".
3. Money, age, to her, are just a number
This woman, who had experienced the storms, did a lot of things in that era, and some even "lifted her head" to do it.
In 1979, when China and the United States formally established diplomatic relations, Li Pei introduced the method of recruiting graduate students from American universities to students and encouraged everyone to apply for self-funded study abroad.
Just after the end of the Cultural Revolution, there was a shortage of talents. Li Pei found English talents who had been beaten as rightists or even imprisoned, and engaged in teaching. As it turned out, her vision was accurate. The "rightist" Xu Mengxiong she invited out of the mountains was the gatekeeper of English documents when Comrade Deng Xiaoping visited the United States in January 1979.
Together with Lee, she also promoted the Sino-US joint physics graduate program to help the first batch of self-funded students in China to go abroad. By the end of the program in 1988, 76 outstanding universities in the United States had accepted 915 Sino-US joint physics graduate students in China. At that time, there was no TOEFL and GRE test, Mr. Li Pei wrote his own questions, and Li Zhengdao selected students at Columbia University in the United States.
In 1987, Li Pei retired, and she happily said that she could take the bus for free.
But she didn't retire a day, and she went on to give English classes to doctoral students until she was in her 80s.
Ma Shizhuang, deputy secretary of the Party Committee of the University of Chinese Academy of Sciences, is a student in Dr. Li Pei's English class. Today, he speaks and lectures on large and small occasions, and he stands. He said that this was learned from Mr. Li Pei, "Mr. Li was in his 70s giving lectures to doctoral students on the podium for several hours, never sat down, not even standing against the podium."
He said he had met many good teachers in his life, but "the greatest teacher I've ever met was Mr. Lee." Mr. Li imparts not only knowledge, but also "anthropology" and the perfection of personality. If an educator is just imparting knowledge, it is nothing more than "from a small hard disk to a large hard disk."
In the eyes of Ma Shizhuang, Mr. Li is a real "big girl". She studied at Yenching University, and after the fall of Peiping, she took a coal ship from Tianjin to Hong Kong, and then traveled to Vietnam to enter the Southwest United University in Yunnan. She studied under the bombardment of the Japanese.
She served as a representative of China at the First World Federation of Trade Unions congress and the first World Congress of Women in Paris. She and Guo Yonghuai abandoned the small three-story Western-style building in the United States and gave the car to the last person to send them off when they returned to China to board the ship.
"What did their generation come back to china for? Her lifelong concern for education and the fate of the country is not something we can fully understand today. Ma Shizhuang said.
In the years of interaction, he felt that this old lady was extremely calm, and there was never a moment of panic or sloppiness. "A person who has come out of the war, experienced countless political movements, traveled through most of the world, lost her husband in middle age, lost her daughter in old age, and what else makes her 'not calm' and 'not calm'?"
"In the past 100 years, mr. Li Pei has not only seen the big people in the books we have seen, but also lived and worked together, and she has seen too many right and wrong, ebb and flow. Money and age are just a number for her. A man who is not even afraid of loneliness, still afraid of death? ”
Ma Shizhuang said that the old man never mentioned a personal matter to the school.
Only once did the old lady call Ma Shizhuang and say, "There is a private matter to ask for school." Ma Shizhuang's heart clucked, Mr. Li had never opened his mouth.
It turned out that there was a bungalow behind the building where Mr. Li lived, which had been locked for a long time and was not used, and Li Pei hoped that the school would give her the key, and she wanted to clean up a place for the elderly in the community to read and read newspapers and play chess.
Recently, Dai Shiqiang, a doctoral supervisor at Shanghai University, brought dried Tofu from Suzhou, Mr. Gu Shulin brought Buckwheat rice from Daliangshan, Li Pei gave Professor Lu Dinghou a mooncake, and 80 or 90-year-old people shared food like children and exchanged how to use WeChat.
However, Mr. Li Pei is becoming more and more oblivious. In an hour and a half, she reminded Dai Shiqiang seven times to help her buy a bottle of medicine exported from Sweden after returning to Shanghai, and when she left, everyone knew that she was asking for the nanny who took care of her.
"Where has Mr. Li ever had a personal affair in his life?" Ma Shizhuang sighed.
He did not like to use words like "rose" to describe Mr. Li Pei, "too light and too fancy, Mr. Li is always smiling to meet tomorrow.".
An old friend also thought that "roses" were too light, and she said that Mr. Li Pei had a great aura, like a magnet, which could attract everything around him.
After graduation, Ma Shizhuang chose to be a teacher, he said, this choice is influenced by Mr. Li Pei, "from Mr. Li, I saw that teachers are the spiritual genes of this society."
4. Explore "Qian Xuesen's Question"
Li Pei's old age began almost at the age of 80.
At the age of 81, she founded the Zhongguancun Grand Forum, which, from 1998 to 2011, held more than 600 sessions a week, and the general hall of more than 200 people was full.
The keynote speakers she invited were also "famous people" in various fields. Huang Zuqia, Yang Le, Zi Zhongjun, Li Yining, Cheng Yuyu, Shen Tianyou, Gao Dengyi, Gan Zizhao, Rao Yi, and other famous masters have all appeared on this big forum.
The content of the pulpit is also diverse: rural issues, the history of ancient Chinese literature, the evolution of celestial bodies, insects, the past, present and future of the Eskimos, the US presidential election, the Tianjin drum and so on.
"Only Mr. Li Pei can please the top wrists in various fields." Some people sighed.
Opening forums is extremely trivial work. Sometimes communicate with the speaker, from the theme to the time determined, back and forth to make dozens of phone calls. Determined the theme, she took her young friends to put up posters around Zhongguancun, she said, not too early, nor at the outlet of the wind, so as not to be blown away by the wind.
Please come and lecture with these big people, all for free. Once, she invited Academician Gan Zizhao, "Old Gan, I don't have a lecture fee for you, at most give you a bouquet of flowers." Academician Gan said: "Your activities are limited in funds, and flowers are exempted." Later, the flowers were also bought by Mr. Li Pei himself.
When he was 94 years old, Mr. Li Pei was really "busy" and closed the large forum. In an office of the Institute of Mechanics, she and a group of old students with an average age of more than 80 years old hold small seminars every Wednesday, "except for winter and summer vacations, usually rain or shine." Such forums continue to this day.
Some people recalled that when discussing the fundamental way out of the "Qian Xuesen's Question", three white-haired old men sat side by side. Mr. Chen Yaosong, a senior professor at Peking University, first said the four words "to rely on democracy", and then, Academician Zheng Zhemin said: "We must have freedom." Subsequently, Mr. Li Pei said unhurriedly, "We must be able to argue." This scene is really wonderful and wonderful in the eyes of others.
She and her old friend Lee Jung-do also discussed the issue. Li Zhengdao said that it was not appropriate to use only the word "answer", so he used "asking for answers to Qian Xuesen's question". Li Zhengdao said that the most important thing in studying is to ask, "to innovate, to learn, only to learn, not to learn."
Mr. Li Pei, who likes music, choreographed "Snow White" when he was young, and played the dwarf, often talks with Li Zhengdao about the relationship between art and science.
During the Spring Festival, Li Zhengdao used charcoal to draw tigers and dogs, and gave her a New Year card. They agree: "Art and science are two sides of the same coin, both seeking profundity, universality, eternity and meaning. ”
Of course, Mr. Li Pei also has a time of madness, no matter what big person is sitting opposite in his living room.
She opposed university enrollment. She opposes the reduction in English class hours at universities now. She shook her head at a vice president of a university sitting on her couch, opposing Renmin University's school of physics and chemistry and Tsinghua University's medical school. She opposed the pessimistic argument that "Peking University should screen 1/3 of the associate professors, and the reform cannot continue".
She advocated that education should not catch up with the hustle and bustle. "Sit tight, don't rush the hustle and bustle." In the past, this sentence was often spoken from Guo Yonghuai's thick mouth, and when he opened his mouth, the smile always radiated from his mouth to the entire face.
When she was in her 90s, she also organized more than 20 experts to translate the papers published in English by Qian Xuesen in 20 years of research in the United States into Chinese and publish "Qian Xuesen's Collected Works (Chinese Edition)". To outsiders, Mr. Li Pei often talks about Qian Xuesen, but rarely mentions Guo Yonghuai, and others say that Mr. Li is too "generous".
5. I'm not lonely at all, and I have a lot of things going on in my head
She could have received many honors, and for decades, countless associations wanted this super energetic old lady to be president, but she refused. The only thing she got was a medal for a long-lived old man or something.
Because there were too many visitors, there were many small benches in the corner of Mr. Li's living room. A child came to see her and asked gossipily: "What do you love about Mr. Guo Yonghuai?" She replied: "Lao Guo is a very real person and will not tell lies." Old Guo has a good temper, unlike Qian Xuesen, who loves to lose his temper. ”
Someone once arranged the couple's story into a stage play "Love in the Sky", and once, Mr. Li Pei went to see the play, and the audience resounded with warm applause. People couldn't read any expression from her face, which seemed to play someone else's story.
This group of young actors had visited Mr. Li Pei. An actor said that when he saw Mr. Guo's last family letter and saw Mr. Guo's self-painted portrait, Mr. Guo was no longer the distant statue. He began to understand Mr. Li Pei's line: "I am waiting for you, I am not old if you do not come back." ”
But the "not old" Mr. Li Pei is indeed old, her back is more and more curved, at first only a small sharp angle, and then the angle is getting bigger and bigger.
Mr. Li Pei, who used to be "dressed in a week is not repetitive" in the eyes of students, and when he went out in his old age, he had to comb his hair without messing up and pin the card, and he couldn't take care of much.
The balcony where she had been lying by the window to send off her guests was covered with dust, the piano had not sounded for many years, and she had forgotten that the painting on the wall was Cornell University, where she and Guo Yonghuai had fallen in love. Memories are breaking up little by little.
In the early years, she was asked what beauty was. "Beauty is a very abstract concept, and mathematics is beautiful," she says. Now, she said bluntly: "If you can do something, it is beautiful!" ”
Few people mention the word "loneliness" to her face, and the old man said, "I am not lonely at all, and I have a lot of things in my head." ”
"It's not so much that she's busy, it's a kind of forgetting." Ma Shizhuang evaluation.
She also passed the ideal age. "I don't have lofty ideals, I can't do it too high, I can only help my friends around me and make their lives better." She said lightly.
Instead, she lamented that she "couldn't do even the little things." Seeing the traffic in Zhongguancun, the cyclists rampaged, and even knocked down the old academicians and old scientists, she wanted to stop the cyclists, but "they ran too fast, I can't catch up."
Despite her growing strength, she tried to fight against the massive bulldozer.
In Zhongguancun, where land is scarce, buildings 13, 14 and 15 are also facing demolition. Li Pei and Qian Sanqiang's wife, Academician He Zehui, and others have called for the protection of these buildings through various channels. In 2012, the Beijing Municipal Committee of the Chinese People's Political Consultative Conference passed a motion calling for the zhongguancun "special building" to be built into a scientific and cultural protection zone. The residents of Zhongguancun sighed: Thanks to these two old ladies!

Academician Zehui has almost become Mr. Li Pei's only remaining old neighbor. When the old people in the courtyard left, when Qian Xuesen left, Mr. Li Pei could still go to send off, and when the news of qian Xuesen's wife and her close friend Jiang Ying's death came, she had no strength to send the last journey, and could only let Li Weige send a wreath on her behalf, sad that she did not sleep well for 3 consecutive months. In 2015, she sent a eulogy to her old friend, 101-year-old Zhang Jinfu.
He Zehui once said to Wen Jiabao, who had visited the door many times and even sat on a small horse once: "I am used to living here, and I will not go anywhere unless I go up the Eight Treasure Mountain." ”
Mr. Li Pei also said to others: "Now, except for the mechanics institute, I stay at home and don't go anywhere." ”
Nowadays, Mr. Li Pei, who is "strong enough to tolerate any turbulence", seems to be more and more clingy, and there are friends who come to see her, she is like a child, making a fuss to let the nanny make food, and when she leaves, she always watches her friends at the window walking away step by step and turning back, little by little.
Taking off the hearing aids, Mr. Li Pei's world became quieter and quieter. It seems that not too many young people are willing to listen to her nagging, and fewer and fewer young people know the name Li Pei.
But everyone who steps into Mr. Li Pei's house in Building 13 will cherish the time of the visit, will try to remember every detail of the home, and everyone understands that after many years, this home is a museum.
