Since the outbreak of the epidemic, many students have experienced a continuous period of study at home and isolation. The three-year epidemic has a profound impact on students, which can be divided into the following points:

Affect learning efficiency: During the epidemic, many students' learning efficiency was affected. Due to the lack of direct communication between teachers and students, it is difficult for many students to get timely guidance and help when studying at home, which leads to the decline of learning efficiency.

Affect learning mood: Many students feel lonely and anxious during the epidemic, which will affect their learning mood. Due to the lack of interpersonal communication, it is difficult for many students to get support and encouragement from people around them, which leads to a decline in their enthusiasm for learning.

Affect learning style: During the epidemic, students had to learn through the Internet, which changed the original learning style. Because online learning is relatively simple, it is difficult for many students to get a variety of learning experiences, which leads to a decline in learning interest.

Affect academic performance: During the epidemic period, due to the decline of learning efficiency and mood, many students' academic performance declined. Many students found that their scores were significantly lower than usual in the exams during the epidemic. This is also due to the lack of direct communication and interpersonal support between teachers and students during the epidemic, which makes it difficult for them to exert their potential in their studies.

Affect physical and mental health: During the epidemic period, many students have been studying and isolated at home for a long time, which will affect their physical and mental health. Due to the long-term lack of physical exercise, the physique of many students has also dropped significantly. In addition, many students still have psychological problems, such as anxiety and depression, due to the long-term prevalence of anxiety and stress.

Generally speaking, the impact of the epidemic for three years on students is far-reaching. Many students are affected by the lack of direct communication and interpersonal support between teachers and students, such as learning efficiency, mood, learning style, academic performance, physical and mental health and so on. Therefore, after the epidemic period, students should be provided with sufficient help and support to help them resume their normal study and life.
