Is it useful to buy comprehensive liability insurance for school treasures, peace of mind and education and training?

Personally, I think buying insurance means buying peace of mind, because sometimes some things are inevitable. If there is a problem with buying insurance, the insurance company will protect it, which can reduce the loss of the institution itself. The comprehensive liability insurance for education and training is mainly aimed at the safety of students in education and training schools. Unlike some insurances, the comprehensive liability insurance for school treasure's peace of mind education and training can guarantee the safety of students inside and outside the school. A colleague of mine had a medical dispute because of a student's accident before, and the parents made trouble every day, so the school could not go. If I had bought comprehensive liability insurance for the school treasure, I estimate that such disputes would be much less.
