Secondly, it is possible for students to have accidents during school, but overall, the safety factor of access is absolutely guaranteed! Even if there are security problems, the school will go all out to solve them, and there will never be serious security problems.
Regarding the problem of sleep, you can rest assured that my sleep is not very good either. I have to rest for an hour at noon every day, so I'm easily woken up. However, during my two years in college, I never got mental illness because of sleep. The problem of students making trouble in the dormitory is an accident, which is lower than the probability of winning the lottery. Moreover, I still lived in a noisy dormitory and slept soundly at night.
Finally, since you have come to Tongda, you must have confidence in her! Only in this way can you gain real knowledge and skills from access! Some people say "bad" for a simple reason. In the words of Uncle Gen of Huazhong University of Science and Technology, you can answer: "The so-called' alma mater' is a place where you can scold her eight times a day but no one is allowed to scold her."
Trust your own judgment, and don't be too influenced by other people's ideas (even if it is "senior"). This is my understanding in Tongda for more than two years. I hope I can help you.
