Yang Zhenning is 20 years old? The master of theoretical physics in the next half century has an extremely distinctive and unique research style and taste. Whether it is field theory and particle physics, or statistical mechanics and condensed matter physics, Yang Zhenning's research work embodies his pursuit of the beauty of physical theory. This pursuit runs through his whole research career. From his student days to the present, Yang Zhenning did not follow the fashion, follow the crowd and follow the rules, but made profound discoveries from physical phenomena and his own physical thoughts to show the beauty of physics. The importance of some work was quickly realized because it was supported by experiments. The most famous example is the work on parity non-conservation in weak interaction. The importance of some work was recognized by other physicists after many years and became the cornerstone of related fields. The most famous example is Yang-Mills? Gauge field theory. Because he is obsessed with his own pursuit, he will put aside those ideas that can't be perfected or show their importance for the time being and wait for the time to be ripe [13]. As the saying goes, "the article is eternal, and the gains and losses are known."

1954, and Mills proposed Yang-Mills? Although I knew it was a beautiful theory, I didn't realize its importance at that time, let alone understand the geometric meaning of gauge field. Yang Zhenning is a physicist, not a mathematician. He summed up basic theories from physical phenomena, and the structure of these basic theories needs to be expressed by mathematics. In the process of pursuing the beauty of physical theory, he is rooted in physical reality. But he has superb mathematical ability and can appreciate the beauty of mathematics.

Yang Zhenning focused on the "cause" of "things" and designed the basic theoretical structure of physics. However, he deeply realized that experimental phenomena are the foundation of physics, paid great attention to new experimental discoveries, had fruitful interaction with experimental physicists, and kept interested in various fields of physics, including some small problems that seemed to reflect the spirit of physics, from which he extracted wonderful physics, but he was not interested in some fields that studied "big" problems but were too speculative. /kloc-after the 1970s, new experimental discoveries in condensed matter physics emerged one after another, and the progress of high-energy physics depended on the development of accelerators, so he paid special attention to condensed matter physics and accelerator physics and encouraged young people to enter these fields [2, 6, 7].

Many ingredients of Yang Zhenning's style and taste come from "seeds" buried many years ago [13, 14]. His love for symmetry is not unrelated to his natural temperament and childhood experience, but also closely related to his undergraduate study of molecular spectral symmetry under the guidance of Wu Dayou and his father's study of group theory. The research of statistical mechanics originated from the guidance of Wang Zhuxi when he was a master. The mathematical ability and appreciation of mathematical beauty shown in many jobs are inseparable from his exposure to mathematics under the influence of his father when he was young [7, 12- 14]. By Fermi? Yang Zhenning keeps interested in many fields.

It is often difficult to separate a scientist's style in scientific research from his personality as a person. From Yang Zhenning, we can see the blending of Chinese and Western cultures, positive attitude towards social progress, the combination of genius and ordinary people, the combination of diligence and wisdom, the combination of sincerity and reality, and so on. All these have something in common with his academic style.
