The lecture focused on the five major sections of "guaranteed admission for postgraduate studies, postgraduate entrance examination, civil service examination, employment, and studying abroad". Through forms such as policy interpretation, data analysis, and case analysis, it systematically constructed the students' cognitive system of further study and employment. It not only provided practical suggestions and valuable guidance for students in terms of pre-examination review and mental state adjustment, but also helped students formulate personalized preparation plans through innovative forms such as the visual presentation of the data of further study in the past three years and the evaluation of the matching degree of target universities.

The class of Condensed Matter Physics for postgraduates organized and carried out the activity of the first lesson of the new semester with the theme of "New Semester · New Starting Point · New Journey", which was presided over by the counselor Zhou Renlai. By introducing the examples of Liang Wenfeng, Wang Xingxing, Han Bicheng, Chen Hang and others, he encouraged the students to persevere in the face of difficulties in the following study and life. In a rapidly changing world, improving innovative thinking and adaptability is an important factor in maintaining competitiveness. He encouraged everyone to move forward actively and boldly, providing guidance for the students' study and life in the new semester, making the students clear about the direction of struggle in the new semester, and laying a solid foundation for future study and scientific research. The students will embark on a new journey with more enthusiasm and firm belief in the new semester.
IV. Build a Solid Safety Line and Protect the Pure Land of Growth

Safety is no trivial matter, and the alarm bell should always ring. Wang Yuge, the counselor of the class of 2023, focused on aspects such as dormitory safety, fire safety, traffic safety, anti-fraud and anti-deception, and network security. Using cases as references, she strengthened students' safety awareness and self-protection ability. She mainly reminded students of potential safety hazards such as the storage and use of illegal electrical appliances in dormitories, indoor smoking, and the use of electric bicycles, and required students to strictly abide by safety regulations to jointly build a safe campus. At the same time, safety inspections were carried out on key areas such as student dormitories to eliminate potential safety hazards and create a safe and orderly campus environment.

Chai Quan, the counselor of Class 1 of Special Optical Fiber Devices and Sensing for postgraduates, guided the students to learn network security knowledge, including identifying network traps, protecting personal information, surfing the Internet in a civilized manner, speaking rationally, and maintaining a clean network space. He led the students to focus on learning the safety regulations of the laboratory, and emphasized to the students that they should strictly abide by the laboratory rules and regulations, use experimental equipment correctly, do a good job in personal protection, and always keep safety awareness in mind.

Dang Fanyang, the counselor of Class 2 of Special Optical Fiber Devices and Sensing for postgraduates, focused on new types of criminal means such as AI face-changing fraud and network dating traps, and guided the students to establish the protection awareness of "not believing easily, not revealing information, and verifying more", and build a solid network security line.
V. Optimize the Academic Atmosphere Ecology and Activate Internal Motivation
