Students, whether in Tsinghua or other institutions of higher learning, may use their mobile phones and fall asleep in class.

However, in colleges and universities, students' participation enthusiasm is generally high, which stimulates their thirst for knowledge and interest in research. Generally, I don't fall asleep, get bored or play with my mobile phone in class, because these will affect my in-depth understanding of professional knowledge. Students hope to achieve better results in knowledge learning and improve their academic level.

In addition, Tsinghua University has formulated relevant classroom management regulations and discipline systems to ensure the seriousness and discipline of students in the classroom, so as to better promote the development of scientific research and academics.

Of course, we need to maintain respect and actively participate in class discussions at all times. I hope that students can consciously abide by the classroom rules and jointly promote academic research and education.
