In an exclusive interview with ReadWrite/Shenzhen Business Daily in September 2020, Yang said he was working to help Shenzhen plan the construction of a medium-energy X-ray free-electron laser. Upon completion, the device will be linked to the planned synchrotron radiation device? intermixed with the planned synchrotron radiation device? that will become the Integrated Particle Facility Research Institute's ? Gemini? and also become an important member of the big science devices in Bright Science City.

Yang Xueming admitted that Shenzhen is still lacking in the construction of major scientific and technological infrastructures, the root cause of which lies in the lack of experience in the research and development of major basic science facilities, and the need for more high-level research institutions and research teams. I hope that with the planning and construction of the Zhongneng X-ray free-electron laser device, we can build a strong research team.

It is worth mentioning that in the same period last year, the team of Zhang Liyuan, a professor in the Department of Physics at SUSTech, was selected as one of the top 10 advances in Chinese science in 2019 for the first time observing the three-dimensional quantum Hall effect.

The Top 10 Advances in Chinese Science? The selection activity is led by the High Technology Research and Development Center (Basic Research Management Center) of the Ministry of Science and Technology of China, and has been successfully held for 16 sessions, aiming to publicize China's major scientific progress in basic research, inspire the scientific enthusiasm and dedication of the majority of scientific and technological workers, carry out the popularization of science in basic research, and promote the public's understanding of, concern for, and support of basic research, so as to build up a good scientific atmosphere in the whole society.

The Top Ten Progresses in Chinese Science? The selection process is divided into three links: recommendation, preliminary selection and final selection.2020, the five editorial boards of China Basic Science, Science and Technology Guide, Proceedings of the Chinese Academy of Sciences, China Science Foundation and Science Bulletin*** recommended 286 scientific research advances, and the recommended scientific advances are all formally published or completed during the period of December 1, 2019 to November 30, 2020 The recommended scientific advances are all officially published or completed between December 1, 2019 and November 30, 2020.

In December 2020, the High Technology Research and Development Center (Basic Research Management Center) of the Ministry of Science and Technology organized a preliminary selection meeting of the Top Ten Advances in Chinese Science in 2020, which was divided into four disciplinary groups according to the disciplinary distribution of the recommended scientific advances, including mathematical and astronomical sciences, chemical and material sciences, earth and environmental sciences, and life and medical sciences, and invited experts to select 31 scientific advances from among the recommended ones. Experts were invited to select 31 advances from the recommended scientific advances for final selection. The final selection was made by online voting, inviting more than 3,200 experts and scholars, including academicians of the Chinese Academy of Sciences, academicians of the Chinese Academy of Engineering, directors of national key laboratories, experts of the overall expert group of some national key research and development programs, and project leaders, etc., to vote on the 31 candidate advances, and advances ranked in the top 10 in terms of number of votes were selected as the top 10 advances in Chinese science in 2020.
