The principle of 'rather clumsy than skillful, rather simple than plain' should become the guiding principle for the vast number of scientific researchers in China to pursue their studies and scholarship. Only by adopting a down-to-earth attitude towards solid knowledge and dedicating patriotism and patriotism to scientific research can China's scientific and technological undertakings truly be pushed to a higher level. As one of the greatest physicists of the 20th century, Mr. Yang Zhenning devoted himself wholeheartedly and tirelessly to his work, leaving an indelible mark on modern physics and even the entire history of science. His favorite motto is' Better simplicity than cleverness, better simplicity than elegance ', which is his attitude towards learning and life. This kind of "clumsiness" is academic determination, which means understanding complex things thoroughly and making uncertain things practical. Yang Zhenning's' clumsiness' is the visible 'stupid kung fu' time and time again. At the University of Chicago, he spent 20 months conducting experimental physics, failed countless times, but never gave up easily; Later, he turned to theoretical physics and, together with Li Zhengdao, derived the law of non conservation of parity. They did not rely on "sudden inspiration", but on "sniffed out loopholes" from the subtle contradictions in a large amount of experimental data. They repeatedly deduced and boldly tried in the "no man's land", ultimately completely changing human cognition; The Yang Mills gauge field theory, regarded as one of the most important fundamental physics theories, is not a quick fix, but a result of more than 10 years of hard work. For Yang Zhenning, the value of science lies not only in breaking conventions and pursuing truth, but also in dedicating oneself to research and striving for it. He said, "Speculation and opportunism have no future. To pursue knowledge, one must be honest and down-to-earth." This "simplicity" is a patriotic sentiment and an unwavering commitment to teaching and nurturing students. From his childhood at Tsinghua University, to his time at Southwest Associated University during times of war, and to his international fame after crossing oceans, Yang Zhenning has always been devoted to his country, seeking every possible opportunity to serve it. For decades, Yang Zhenning has been tirelessly traveling around in order to accelerate China's scientific progress. After returning to Tsinghua University, at the age of 82, he still insisted on teaching undergraduate students the course of "General Physics". He also donated $1 million in cash, raised over $15 million in funds, recruited outstanding scholars from home and abroad, and regarded founding the Tsinghua University Institute of Advanced Studies as his "last worthwhile thing to do in his life". On the wall of 'Returning to My Hometown', there hangs a five character poem written by Yang Zhenning: 'The new heaven in China is changing, and the mission of our hometown is heavy. As a student, I will guide the way.' Yang Zhenning has long proven himself, but still chooses to love his country and be simple in life and work. He poured this simple emotion into every detail of teaching and learning. Ge Molin, an academician of the CAS Member and professor of the Chen Shengshen Institute of Mathematics at Nankai University who has been in contact with him for nearly half a century, always remembers Yang Zhenning's words: "We should be simple, not superficial." The universe is not deceitful, and the formula is not clever. Yang Zhenning's life experience and the saying "It's better to be humble than clever, and it's better to be simple than elegant" both tell us an undeniable truth: "Being humble to the extreme is actually the most clever; Only when 'Park' goes deep can one see the true chapter. Great scientific discoveries often stem from excellent scientific qualities. True long termism often hides in those 'clumsy efforts'. General Secretary Xi Jinping emphasized the need to aim at the forefront of world science and technology, seize major trends, play the "first move" well, lay a solid foundation and reserve for the long term, be willing to sit on the cold bench, be brave to be the ones who plant trees and dig wells, achieve significant breakthroughs in forward-looking basic research and leading original achievements, and consolidate the foundation of building a world science and technology power. China's technological development has reached today, and there are more and more "long boards" that are leading the way. The more we enter some basic and cutting-edge fields, the more we need to put in the "stupid effort" of "sitting on the bench for ten years". The principle of 'rather clumsy than skillful, rather simple than magnificent' should be the guiding principle for the vast number of scientific researchers in China to pursue their studies and research. Only by adopting a down-to-earth attitude towards solid knowledge, and investing patriotism and patriotism into scientific research, can China's scientific and technological undertakings be truly pushed to a higher level. For more people, in the current era of rapid technological development and fast-paced production and life, the pursuit of "cleverness" and "elegance" has a strong appeal - they want to be glamorous, become famous overnight, and take the lead... However, such a "short, flat, and fast" foundation is not reliable. Only by getting rid of impetuosity, returning to the original, and being honest, can we take a broader path in life and realize the value of life in the great cause of promoting Chinese path to modernization.
