Generally speaking, there will be no major adjustment in the changes of the class committees in universities, because most people in a class in universities don't want to serve as class committees, and there are too many miscellaneous things.
Universities have a history of thousands of years. At first, it mainly developed from Germany, Britain and other countries. Modern universities in China originated in the West, which evolved from European medieval universities, British universities, German universities and then American universities. No matter what era the university is, it is a creative inheritance rather than a denial of previous universities.
The word "university" comes from the Latin Universitas Magistorum et scholium, which roughly means "the community of teachers and scholars". The modern university system has always been in the University of Eugen in the Middle Ages, which was established and evolved from the cathedral school in Italy in the Middle Ages.
