In March, 20001year, on the eve of the 90th anniversary of Tsinghua University, President Wang Dazhong wrote "Be strict in studying and be sincere in being a man", pointing out that the school motto is "self-improvement, respect for morality and carrying things", the school spirit is "actions speak louder than words" and the style of study is "preciseness, diligence, truth-seeking and innovation", which is the precious spirit left by several generations of Tsinghua people.

At the beginning of the school, Tsinghua was famous for its strict and complete rules and regulations. At one time, there were more than 90 regulations, which made teachers and students form a style of obeying the system and stressing efficiency. 1September, 928, Luo Jialun became the principal. A month later, after investigation, he boldly dismissed a group of unqualified professors. During the period of 1946, Mei Yiqi was in charge of the school, and his little daughter didn't go to Tsinghua, so she wanted to go to another school. Zhu Ziqing, a famous scholar, is very strict with himself. He wrote in his diary that he had dreamed many times that he was unable to find another job because of lack of knowledge. After waking up, he was sweating all over, so he worked harder. Tsinghua attaches great importance to sports. According to Mr. Liang Shiqiu's memory, there must be an hour of forced exercise every afternoon. He also made up the exam because he failed in swimming, and tried his best to barely pass.

Liang Sicheng, a master architect, stressed that architects should be responsible for the project, and each design document should be clear and accurate, and even the font size is strictly regulated. Nobel Prize winners in physics were deeply loved by Ye during their studies. In an exam, although he did well in theory, he only got 83 points because the experiment was not rigorous enough. This test paper has been kept by Ye Lao. After learning this, Li Zhengdao had mixed feelings and lamented that it was the strict requirements of the teacher that made him develop the habit of paying equal attention to theory and experiment.

Since the founding of New China and the reform and opening up, Tsinghua people's rigorous and pragmatic tradition has continued to flourish. After Jiang Nanxiang became the president of Tsinghua, he strongly advocated not only being superior to others, but also books and being practical. He also reminded cadres and teachers to be "warm-blooded animals" and not to change with external influences. Xue Qikun, the discoverer of quantum anomalous Hall effect, has a nickname: "Academician 7- 1 1 (July-11)". He plunges into the laboratory at 7: 00 every morning and works until 1 1. He has been doing this routine for 20 years. Academician Qian Yi of the Institute of Environment holds several posts, but no matter how busy she is, she always puts students first. She has been teaching for 60 years and is known as the "most beautiful teacher".

1992, 60th anniversary of Tsinghua University Electrical Engineering Department. In his congratulatory message, Zhu Rongji deeply recalled the inculcation of Professor Zhang Mingtao, the old dean of the department, to young students: "Be rigorous in your studies, be serious and rigorous, be rigorous and realistic, and be a master from a strict teacher. Upright, aboveboard, honest and upright, upright and upright. "

Being rigorous and realistic is not only a solemn style of study, but also a noble character that Tsinghua people has always adhered to and persisted in for a hundred years. It flows in Tsinghua's blood, handed down from generation to generation, lasting forever.
