On May 10, 2023, Prof. Fang Yu, academician of the Chinese Academy of Sciences and chairman of the Xi'an Association for Science and Technology, was invited to Xi'an Tieyi Middle School to participate in the "Academicians Enter Campus" science popularization event hosted by Xi'an Science and Technology Association and Xi'an Radio and Television (Group), and gave a report titled "The Importance of Basic Science - Taking Chemistry as an Example".

The event was broadcast live in 6 schools, including Xi'an Tieyi Middle School Binhe High School, Xi'an International Port District Tieyi Zhonglugang High School, Shaanxi Xi'an Middle School, Xi'an Jingkai No. 3 Middle School, Yichang No. 1 Middle School, and Yichang Yiling Middle School. Officials of the provincial and municipal science and technology associations, Xi'an Radio and Television Station (Group), and Beilin District participated.

Fang Yu used vivid language to speak from two aspects of the value of basic science and the role of chemistry, and he talked about the glorious tradition of China's older generation of scientists in scientific research to serve the country; the scientific spirit of pursuing truth and bravely scaling the peak; and innovative, rigorous and realistic academic atmosphere. He used the stories of scientists to inspire students and let them realize the noble spirit and excellent qualities of scientists.

Fang Yu said: "In my opinion, the characteristics of chemistry discipline are to create new substances, discover new functions, and realize new applications, that is, chemistry can and should do research that 'stands firm on the ground and reach to the sky'." Fang Yu said that China missed the first three industrial revolutions and must seize the fourth one with big data and artificial intelligence as the core. In the report, he also introduced the current status and future of sensors and his research results in the field of sensors to teachers and students.

Fang Yu also encouraged the students to inherit, carry forward and practice the spirit of scientists, combine personal ideals with major national needs, bravely become pioneers in emerging fields and interdisciplinary fields, and leaders in key scientific and technological fields, seize the commanding heights of world scientific and technological development, and make greater contributions to national rejuvenation and national prosperity and progress.
