Chinese mathematicians Wang Hong and Deng Yu were awarded the Fields Medal, known as the “Nobel Prize of Mathematics,” in July, sparking widespread discussion in China and around the world about the rise of Chinese mathematics in the 20th century. Wang Hong solved the famous three-dimensional Kakeya conjecture, while Deng Yu tackled the sixth of Hilbert’s 23 problems, proposed at the International Congress of Mathematicians in 1900, and achieved significant results.
I studied mathematics at university, as well as the history of mathematical development, and have also worked in mathematics education and training. Naturally, I am pleased to see Chinese mathematicians receiving international recognition. Through this feature, I hope to look back with readers at the arduous path taken by Chinese mathematical research over the past century. I believe this was not a smooth, linear path of upward development, but rather one marked by ruptures, the passing of the baton overseas, and subsequent new beginnings.
Many early mathematicians received their training outside China before returning to China to work hard to establish the foundations of mathematical research, only to suffer devastating setbacks during the Cultural Revolution. We then saw Chinese mathematicians who had settled overseas demonstrate the mathematical talent of the Chinese diaspora and advance mathematical research around the world. In the contemporary era, China has gradually developed a selection culture centred on mathematics competitions, against which a new generation of mathematicians has emerged.
The following section traces this generational journey through several representative figures. I offer this as a tribute to Wang Hong and Deng Yu, and to the Chinese people who have worked hard in mathematical research around the world for more than a century.
I. Pioneering and Interruption: From Xiong Qinglai, Hua Luogeng and Chen Shengshen to Chen Jingrun
The true beginning of modern mathematics in China cannot be separated from a group of early pioneers. They established departments, identified talent, developed academic traditions, and struggled to keep the flame of research alive during difficult times.
Xiong Qinglai (1893–1969) was known as the “Bole of the Chinese mathematical community.” He founded the Department of Mathematics and a research division at Tsinghua University and personally compiled Chinese-language textbooks. More importantly, he had a keen eye for talent. In 1930, after seeing a paper written through self-study by Hua Luogeng in the journal Science, he overcame opposition and brought Hua Luogeng, who had only a junior middle school education, to Tsinghua University as an assistant. This gave him the opportunity to sit in on mathematics classes and develop rapidly. Xiong later recommended him to study at Cambridge. Without this exceptional support, Hua Luogeng’s life trajectory might have been completely different.
Hua Luogeng (1910–1985) embarked on his mathematical career under Xiong Qinglai’s support. Born into a poor family in Jintan, he became a self-taught mathematician. In 1936, on the recommendation of Norbert Wiener during his study visit, Hua Luogeng went to Cambridge to study number theory under the mathematician Hardy, publishing 15 world-class papers within a year. Hua Luogeng later became a professor at the University of Illinois. In 1950, he gave up the favourable conditions he enjoyed in the United States and returned to China, becoming director of the Institute of Mathematics at the Chinese Academy of Sciences. He worked hard to establish China’s own mathematical research capacity and trained young talents, including Chen Jingrun.
During the Cultural Revolution, Hua Luogeng, like many other scientists, came under attack. Afterwards, he shifted significantly towards applied mathematics, actively promoting the “Optimization Method” and “Overall Planning Method.” He led small teams across more than 20 provinces and cities throughout the country, going deep into factories, rural areas and construction sites, applying mathematical methods directly to production practices and serving national economic development. This experience led him from pure theoretical research towards more practical applications and promotion, and became one of the best-known aspects of his later work.
At the same time, Hua Luogeng placed great importance on mathematics competitions from an early stage. After studying the Soviet mathematics Olympiad in the 1950s, he actively advocated for the organisation of mathematics competitions for secondary school students in China. In 1956, pilot competitions began in Beijing, Shanghai and other places. After the end of the Cultural Revolution, in 1978, he personally presided over the national secondary school mathematics competition involving eight provinces and cities, and wrote several popular mathematics booklets for young people. He hoped to stimulate interest and discover talent through competitions. These early efforts planted the seeds for the later Chinese tradition of selecting mathematical talent through competitions, although the highly competitive culture of competitions beginning in primary and secondary schools today only gradually took shape and became extreme after his death.
Chen Shengshen (1911–2004) completed his undergraduate education and early research training entirely in China. He studied at Nankai University (1926–1930) and Tsinghua University, completing his master’s degree at Tsinghua and beginning preliminary research in differential geometry. It was not until 1934 that he went to the University of Hamburg in Germany to pursue his doctorate. It was precisely this foundation established in China that enabled him to quickly emerge on the international stage. After completing his doctorate in Germany, he was invited to the Institute for Advanced Study in Princeton in 1943, where he completed important work. He later taught for many years at the University of Chicago and the University of California, Berkeley, and founded the Mathematical Sciences Research Institute in the United States in 1981. Although he became an American citizen, he remained deeply concerned about mathematics in China. After his first visit to China in 1972, he travelled back and forth frequently. In 1984, he was invited to establish the Institute of Mathematics at Nankai University, helping China reconnect with the international mathematical community. He often said, “Mathematics has no borders, but mathematicians have a motherland.” Chen Shengshen and Hua Luogeng were both leading figures in Chinese mathematics in the 1930s and 1940s. They met at Tsinghua, worked together at Southwest Associated University, and maintained a lifelong friendship.
Chen Jingrun (1933–1996) was a direct continuation of this line of inheritance during difficult times. After being recognised by Hua Luogeng, he was transferred to the Institute of Mathematics of the Chinese Academy of Sciences. Under extremely basic conditions, he made important progress on the Goldbach conjecture and became a symbolic figure of Chinese mathematics during that era.
However, precisely because of his excessive devotion to mathematics, he suffered greatly during political movements. During the Cultural Revolution, Chen Jingrun was criticised as a typical example of someone who “took the path of focusing on expertise while neglecting political ideology,” and was subjected to struggle sessions and isolation. He lived in a room of only about six square metres at the Chinese Academy of Sciences. Without a desk, he would lie on the bed and perform calculations. Despite being physically weak and suffering from multiple illnesses, he endured criticism during the day and secretly conducted research at night. On one occasion, he was so absorbed in a mathematical problem that he forgot the time of a meeting, resulting in harsher criticism.
This experience of being persecuted “because of his love of mathematics” was not an isolated case. During multiple political movements after the founding of the People’s Republic of China, many scientists devoted to academic pursuits were regarded as being “specialised but not politically committed.” Their research was forced to stop and their careers were damaged. The obvious decline and rupture in China’s domestic mathematical development during that period were closely connected to this environment.
This pioneering period suffered a devastating setback during the Cultural Revolution. Many mathematicians, including Hua Luogeng and Chen Jingrun, were attacked and persecuted, while normal research and teaching almost came to a halt. The development of mathematics in mainland China experienced a clear rupture during this period. The first stage of pioneering efforts came to an end.
II. Passing the Baton Overseas: Yau Shing-Tung and Terence Tao
When mathematics in China fell into a low period, Chinese mathematicians who had settled overseas became important successors in carrying the baton.
The trajectory of Yau Shing-Tung (1949–) is almost a complete illustration of “reaching the peak overseas while continuing to give back to China.” He grew up in Hong Kong and later went to the United States for further study, where he studied under Chen Shengshen. He taught at Harvard University for many years and achieved great accomplishments in the international mathematical community. But he never limited himself to the American academic community. Since his first visit to China in 1979, he has spent time in China and Hong Kong almost every year for more than four decades, promoting mathematics education and research, participating in the establishment of multiple mathematics centres, setting up awards and competitions, and helping to cultivate young people. In 2022, he retired from Harvard and returned full-time to Tsinghua University, focusing most of his efforts on cultivating mathematical talent in China. His choice symbolised the completion of a cycle for a generation of overseas Chinese mathematicians: “departure—reaching the peak—return.”
Terence Tao (1975–), meanwhile, represents another form of contribution. Born in Australia and with ancestral roots in Guangdong, he demonstrated extraordinary talent from an early age and became well known in the international mathematical community at a very young age. Unlike Yau Shing-Tung, whose focus was on institutional development, Terence Tao has contributed more through writing, lectures, blogs and public activities, promoting mathematical ways of thinking and research culture around the world. He has allowed many ordinary people to experience the appeal of mathematics and has also become an important role model for the younger generation.
Together, the two demonstrate the role of Chinese-diaspora mathematicians in carrying the baton after the Cultural Revolution: one became deeply involved in rebuilding mathematics within China, while the other enhanced the visibility and appeal of mathematics on a global scale.
III. Contemporary Faces Under Competition-Based Selection: Wei Dongyi, Liu Zhiyu, Wang Hong and Deng Yu
Entering the 21st century, China gradually developed a selection culture centred on mathematics competitions. Gold medals at the International Mathematical Olympiad and results in national competitions became important tickets to entering top universities. Wei Dongyi, Liu Zhiyu, Wang Hong and Deng Yu are all representatives who grew up in this environment, yet they have taken completely different paths.
Wei Dongyi (1991–) won full-score gold medals at the IMO twice. After being admitted to Peking University through direct recommendation, he chose to remain in China and is now a teacher at Peking University. Quiet and focused, he devotes almost all his energy to mathematics. Although prestigious overseas universities once extended offers to him, he chose to stay. His path is one of “putting down roots locally,” participating in the internal development of Chinese mathematics through long-term, stable research and teaching.
Liu Zhiyu (1988–) was also an IMO full-score gold medalist. After graduating from Peking University, he could have gone to MIT for further study, but instead chose to become a monk. More than a decade later, he returned to secular life and turned towards psychological counselling and related work. His story reminds us that mathematical talent does not necessarily have to follow the path of “continuing to conduct research.” The high-pressure elite education system and expectations associated with early achievement may lead people to reflect more deeply on the definition of “success.” His choice is not a failure, but another exploration of the meaning of life.
Wang Hong (1991–) and Deng Yu (1989–), meanwhile, represent the most common high-potential pathway today: completing their undergraduate studies in China (both studied at Peking University), then going overseas for further education, and ultimately achieving important accomplishments on the international stage. In 2026, the two were awarded the Fields Medal simultaneously, becoming the first mathematicians holding Chinese citizenship to receive the honour. Their experiences demonstrate that China’s current competition and undergraduate selection systems are capable of identifying world-class potential talent, but the most important breakthroughs often still need to be achieved in more mature research environments overseas.
The different choices made by these four people form a picture of the contemporary era: some choose to stay and deepen their work locally, some step outside the academic path to question the meaning of life, and some go overseas and achieve breakthroughs within global networks. None of these choices is superior to another.
IV. What These People Tell Us About Changes in Chinese Mathematics
Looking back over the past century, we can broadly identify several distinct generations:
The pioneering generation (Xiong Qinglai 1893–1969, Hua Luogeng 1910–1985, Chen Shengshen 1911–2004, Chen Jingrun 1933–1996): They worked to establish the foundations, but suffered severe disruption during the Cultural Revolution. Hua Luogeng turned towards application and promotion in his later years and planted the early seeds for mathematics competitions; Chen Jingrun, meanwhile, suffered severe persecution because of his devotion to mathematics, becoming a microcosm of the circumstances faced by intellectuals during that era.
The overseas baton-passing generation (Yau Shing-Tung 1949–, Terence Tao 1975–): They achieved accomplishments on the international stage while giving back to China in different ways.
The competition-based selection generation (Liu Zhiyu 1988–, Deng Yu 1989–, Wei Dongyi 1991–, Wang Hong 1991–): They grew up under a selection system centred on mathematics Olympiads. The system has been able to consistently produce young people with high potential, but how to truly transform this potential into original research remains a challenge.
From Xiong Qinglai to Hua Luogeng, then from Hua Luogeng to Chen Jingrun; from Chen Shengshen to Yau Shing-Tung; and then to today’s Wei Dongyi, Wang Hong and Deng Yu, this line of inheritance has experienced ruptures but has never been completely broken.
Today, Chinese mathematics has a huge population base and a rigorous selection system, while an increasing number of young people are choosing to stay or return. However, a research environment that genuinely allows long-term exploration, tolerates failure and does not rush for immediate results is still gradually taking shape.
The Fields Medal is not the end, nor is it a simple scorecard of national strength. What truly matters is whether talented young people can grow in a relatively relaxed and intellectually deep environment, while being allowed to make different choices in life.
From Hua Luogeng to Wang Hong and Deng Yu, this journey has already come a long way. But the road ahead may require even more patience and tolerance than the road already travelled.
