There are no classes in universities on weekends, and teachers can conduct academic research, writing, reading, attending academic conferences and other activities on or off campus. In addition, teachers can also use this time to declare and manage scientific research projects, such as writing scientific research plans and applying for scientific research funds. At the same time, teachers can also use this time for self-improvement and professional training in education and teaching, such as attending education training classes and listening to lectures by other experts. In a word, teachers who have no classes at university weekends can make full use of this time to improve their professional quality and ability and make contributions to better serving students and society.
